P2563 error code, flashing coil light, flashing EML (engine) light

[MHDxMK5BK]

This came on a few days ago, not used the car much since. I've searched around the other postings with this code in them and may well be the turbo actuator.

I'll keep you posted on how this unfolds and if anyone has anything else to check then please do let me know.

Did about a 50 mile run today there and back.

The EML stays on but when cruising steadily the coil light turns off but on braking for the next roundabout the dashboard dings and the coil light is flashing again.

This leads me to believe I've got a vacuum issue somewhere maybe. Best do some more research and checks as I'll be mighty cross if I get the turbo actuator changed just to find a vacuum pipe on the egr cooler is broken as was the case on this (http://www.vwaudiforum.co.uk/forum/showthread.php?143679-P2563-code&highlight=P2563) chaps car.

More than likely the diaphragm in the turbo actuator is leaking, a very common problem. Unfortunately there is no VAG repair kit for the BMR engine. Test the diaphragm by applying a vacuum to the actuator port and seeing if air can be drawn through.

[MHDxMK5BK]

Found a diagram (http://workshop-manuals.com/volkswagen/golf-mk5/power_unit/4-cylinder_diesel_engine_%282.0_l_engine_4_valve%29/exhaust_turbocharger_g-charger/charge_air_system_with_turbocharger/vacuum_hose_schematic_diagram/engine_codes_bmn_bmr_and_buz/).

Crasher: Tried to get the pipe off the Charge pressure control solenoid valve -N75- and gave up as was in danger of snapping something. I'll dig out a bit of pipe from the garage and have another go tomorrow. As the BMR has no repair kit what is required here and what's the ballpark costs?

[Crasher]

I take the pipe off the actuator (get a pointed hook under it to break its rubber grip) and then apply the vacuum, if air just pulls through you know what is wrong. When we get them in with this we send the turbo off for overhaul and the total tends to be around £900 all done including and oil and filter change but sometimes we do have to replace the oil feed pipe if it twists.

[MHDxMK5BK]

It's at times like this that I miss my Mondeo dearly! A diaphragm perforates and you have to replace a turbo! Outrageous!

Thanks though for the info, it's surprising you cannot just get the actuator separately, maybe I can find one somewhere...

[Crasher]

If the Mondeo used the turbo from the same company it would be the same problem. Even if you get the actuator it has to be precisely set up on a flow bench. On the later engines VAG brought out a repair kit which we fit loads of and so do other people but often people make a right mess of it as it has to be very accurately set up on the car using measuring blocks and a vacuum pump. We find the penis enlargement kit pump comes in handy.

[MHDxMK5BK]

Got the turbo actuator's vacuum pipe off in the end and sure enough I can suck air through it so looks like the diaphragm is goosed.

Just got to shop around a bit to see if I can get the actuator replaced rather than a turbo replacement / overhaul etc.

[Teflon]

The actuator adjustment is supposed to be set up on a turbo flow rig. They claim that if you set it wrong you risk over boosting. I don’t know if this is hogwash, but I wouldn’t want to take the chance on blowing my engine up.

If the turbo is coming off for a set up you might as well get it reconditioned. Prices used to be £350-550 on a 48 hour turn around but I suspect they will have risen a bit now.

[Crasher]

It is a Garrett GTB1749MV turbo, part number 757042-0014 but I can't find a supplier for the actuator or even the part number!

[MHDxMK5BK]

Genuine VW turbo actuator fitted for £220 by a local independent. All sorted.

[Crasher]

Something is amiss here, you say in your signature that the car has a "TDI CR DPF......BMR engine" and you have a new actuator fitted. The BMR isn’t Common Rail, it is a PD and VW don’t list an actuator repair kit for a BMR so your engine code will be CBBB which is why myself and Teflon didn't give you the correct information about repair kit 03L 198 716 A, which is £130.88 and this can be fitted on the car and set up with VCDS. If I had read your first post a little more carefully I would have realised this as the BMR does not have a fuel rail pressure sensor.

[MHDxMK5BK]

You are correct! There is some conflicting information in the paperwork that came with the car and it didn't occur to me to cross-check.

Signature updated the numbers from the service book so hopefully this makes more sense.

Hi there, apologies for resurrecting the old thread, but I am struggling with this same issue. My wife and I are on our year long sabbatical and our VW Crafter motorhome is our home and we've broken down in the North of Italy.


The brief history of the 2010 VW Crafter base vehicle. At round 115,000 miles, new NOx sensor, O2 Lambda sensors changed. Nerings re-build turbo installed, due to the old one having too much movement by SMG Van on Croydon.


Less than 3 thousand miles into my 12 months sabbatical on the continent (EU), the MIL light flashing, glow-plug light flashing and engine dropping in/out of limp mode. Switch off ignition for a bit, switch back on, OK for a bit then back to limp. In between, the turbo making a strange blow-off? noise when de-powering between gear changes (when not-yet-in-limp-mode).


This seemed to happen after driving it hard up a couple of steep mountain passes in the north of Italy, then cooling down quickly in the camp site, high in the mountains.


VCDS came up with two faults in the engine module:

Took it to VW dealer in Italy, which made a provisional repair "comando geometria variabile turbo" (english: "command variable turbo") and then gave me a bill to replace the whole turbo for 2000 EUR, which I not so politely declined (as it took them a week to tell me that, while I was flushing money into temporary accommodation). Not having a job for a year, doesn't help either.


Anyway, after removing the car from the workshop as-is, it seemed to be working fine for a bit. I put some diesel engine cleaner in the tank when I filled it up and gave it an Italian tune-up for about 60 miles. I also sprayed WD-40 up and around the turbo actuator piston.


The glow-plugs/MIL lights still randomly come up and also randomly disappear, all without any noticeable loss of power or strange noises from the turbo.


The only fault that keeps being (re)logged is the Turbocharger Boost Control Position Sensor Circuit. The second Boost Pressure Regulation fault has not come back.


I suspect either vacuum leaks, turbo actuator fault or simply carbo build-up in the turbo/sticking vane because of hard driving/fast cool down/crap tractor diesel. Could be a faulty sensor as well, although the Italian workshop checked all the electrical connections, presumably doing some form of sensor testing with an Ohm meter.


In either case, I don't think a new turbo-compressor is the most economical or environmentally friendly solution in this case.


Does anyone have (a) any specific advice on how I can troubleshoot this further with very limited tools; and/or (b) know of a good independent mechanic in Germany, Switzerland, Italy, France, Spain, etc. who can look at this problem without going straight down the turbo replacement route?


I have VCDS with me and a multimeter, apart from some spanners, but not really enough to start pulling turbos off the engine :)


Any advice welcome.


Cheers!

[Crasher]

What is the engines type code? From the description it sounds like a CE?? series with the electronic turbo actuator, the diaphragms on these split. There is no alternative to taking off the turbo and having a new actuator fitted, IF you can find someone who can/will do this or if they can even get hold of an actuator. Remove the vacuum pipe to the N75 valve and suck on the pipe, i.e. the actuator it is connected to, can you draw air or is there a vacuum resistance?

[RichardSEL]

2.5L TDi CR -- post your full Autoscan so Derv heads in here can see more of what VCDS is reporting? Then clear all faults to see what, if anything now, comes back.

Have you had limp mode since:
>>The glow-plugs/MIL lights still randomly come up and also randomly disappear, all without any noticeable loss of power or strange >>noises from the turbo. The only fault that keeps being (re)logged is the Turbocharger Boost Control Position Sensor Circuit.

[Chainik]

Right, so no limp mode since. Power seems to be OK also, can't notice a drop. Only on fourth gear up a hill I can hear an occasional "whoosh" / "wobble" noise from the engine when de-powering. In third and below, the turbo appears to be "whistling" normally.

Now the same code comes up every-time I start the engine after clearing it.

Note, this code comes up while idling, about a minute of the engine being switched on (not yet moving). This is represented on the dash by MIL and the glow-plugs warning (both flashing). Sometimes the glow-plugs warning disappears and the MIL becomes solid.

So, I've sucked on the hose and there appears to be vacuum resistance. I can see the piston move as my face goes red.

In any case, if this is the problem, any ideas where I can find a garage in Europe which will know what to do. I suspect even if I brought in a new actuator and asked a random garage to fit it, I would get a blank stare.

I guess I could always take it to VW and get a whole new turbo, but that is the absolute last resort...

Here are a couple of photos of the hose connecting the actuator and the valve. There are no hose clamps on this, so I am not sure if this could be the issue?

[Crasher]

A CEBB engine then..... You need to check the turbo actuator diaphragm to see if it is leaking.

[Chainik]

OK, thank you. I am trying to find someone capable around where we are in Italy, but this is proving somewhat difficult.

I also forgot to mention that the brake vacuum pump is making a tapping noise on occasion (see related):
Unusual tapping noise (http://www.vwaudiforum.co.uk/forum/showthread.php/34612-Unusual-tapping-noise)

Could this be at all related to my turbo issue?

[Crasher]

Yes, the system is vacuum controlled and totally dependant on a good vacuum throughout the system, one leak anywhere can shut three systems down.

This code probably has nothing to do with vacuum or turbo as such. It is a code that is not used on your vehicle as you do not have a position sensor. I suspect the designers are trying to tell you that the Atmospheric pressure and map sensors do not agree with each other. If this code appears on switch on but no other problems occur, I would ignore it for now. It only needs fixing if it is causing limp mode.

[Chainik]

Oh, very interesting... Would it make a difference I am driving 1-2km high up in the mountains?

[Crasher]

you do not have a position sensor

The CEBB engine uses a Mitsubishi Heavy Industries 49T77-07460 or 49T77-07535 which according to ETKA does not have a position sensor for the charge pressure positioner, a G581, BUT the wiring diagram on ELSA page 17 current tracks 215>217 clearly shows one, the pictures posted of the turbo show it has the composite bodied positioner and in the ELSA instructions for removing the turbo it states “pull off vacuum hose and connector from turbocharger”, a proper picture of the actuator would solve the problem. Chanick, can you PM me your UK reg number?

[Chainik]

Thanks Crasher, PM sent.

FWITW, the actuator on my van looks exactly like the one in the images above.

[Crasher]

Yes it is a CEBB engine as your ECU number indicated BUT it is a 2011, not a 2010 but ETKA FI suggestion infers that it has the non VNT turbo 076 145 702 C which is obviously wrong. The 076 145 702 C is the same as the later D and Q which is the one in the picture. The actuator can be replaced but it has to be set up on the bench, you need a turbo rebuild specialists help. http://www.be-turbo.com list the actuator under their part number 206208

[martin1810]

It seems I was wrong. I believe your vehicle uses an edc17cp20 ECU. If this is the case, it can produce this error code because of a possible Nox error (exhaust gas fault). My best guess is that the lambda regulation check is looking for a turbo actuator position so that it can calculated expected oxygen levels to determine lean or rich mixture. So when you switch on ignition the lambda check is failing because the actuator positioner is either not working or giving an out of range signal. Basically the ecu is trying to predict fuel air/ratio using turbo boost level. If the actuator does not give a position, the ecu cannot do its calculation. As long as this does not cause limp mode, I would ignore it. It should be ok to ignore the fault because when the engine is running the ecu can use other methods to calculate (probably turbo pressure) which do not rely on the actuator position.

[Chainik]

Thank you Martin, that is a very useful insight.

It is worth noting, that both NOx and O2 Lambda sensors were replaced at the same time as the re-conditioned turbo was installed.

Prior to those replacements, the code "09571 - Turbocharger Boost Control Position Sensor Circuit
P2563 - 000 - Implausible Signal - Intermittent" was previously coming on also, on top of the following codes:

009571 - Turbocharger Boost Control Position Sensor Circuit
P2563 - 000 - Implausible Signal - Intermittent

008598 - Oxygen (Lambda) Sensor B1 S1
P2196 - 000 - Signal too High (Rich) - MIL ON (and)
P0130 - 000 - Malfunction in Circuit - Intermittent

008863 - NOx Sensor 2 Bank 1
P229F - 000 - Implausible Signal

008871 - NOx Sensor 2 Bank 1; Heating Circuit
P22A7 - 000 - Implausible Signal


Not sure if this give any more insight into my problem.

We have been driving the van since up and down the mountains and apart from the glow-plugs and MIL flashing/solid, we've not had any issues with loss of power or going into limp mode.

But it does sound to me that there could be a few different problems with the system(s).

Cheers!

[Crasher]

Have you checked the vac system at its servo pipe source to see if you can draw air?

[Chainik]

I only checked if I could draw through the actuator (with my mouth), but only suceeded in moving the VNT rod slightly. I unplugged the hose going to the solenoid? and sucked on it.

Will try to get a hand vacuum pump and test the lines properly (or a qualified mechanic), whichever comes first :)

[Crasher]

Yes you need a Mitty Vac type unit to test the actuator. Sucking on the vacuum source pipe using the Mk1 mouth is good enough to check the integrity of the system though.

[martin1810]

The previous faults were part of the same system but I don't think they relate to the current situation. My best guess is that ECU isn't getting a "rest position" or "first movement" signal from the actuator at Ignition on.
The ECU probably wants this signal so it can predict fuel requirement at start before sensors can provide data. This situation may only exist for a fraction of a second because once the engine starts the ECU can read all the sensors. The ECU will set a fault because its calculations have failed. IF the ECU's new "engine running" calculations failed you would get more faults and limp mode. To investigate this further you need an electronics guy and an oscilloscope. It is probably simpler to ignore the fault for now and get it fixed later.

Thank you Martin, that is a very useful insight.

[niall campbell]

I would also point that pipes can collapse inwards , blocking airflow and not showing any sign of a leak

[Chainik]

Thanks again, the vehicle hasn't gone into limp mode since, so I am also inclined to ignore the errors. It's not like I have many other options at the moment.

Cheers!

[Chainik]

The only thing I would add, is that now sometimes we don't even get get warning lights on the dash at all (after clearing). This absence seems to be accompanied by a completely different smell coming from the exhaust (DPF burn-off?).

Also, when the warning lights return and normally when travelling up-hill, I notice the engine will sometimes start idling at 1000 RPM, rather that the normal? ~ 750 RPM. Turning it off and on, seems to go back to circa 750 RPM.

[Crasher]

If it is combusting correctly then the cat and DPF will make the gases smell completely different.

[Chainik]

Just a quick update: had the vehicle in a local friendly workshop, which checked all the vacuum lines, pump, etc. The actuator held vacuum at 700mB, so everything seems OK from a mechanical stand-point.


The "implausible signal" is still coming up on the ECU every time the machine is started, but it doesn't seem to affect it's performance. It hasn't gone into limp mode since the initial incident 2-3 weeks ago.


Perhaps the issue is with one of the sensors...

[Crasher]

I would suspect the actuator is incorrectly set up.

[Chainik]

Is it "field adjustable" or does the turbo need to go on a bench?

[Crasher]

There is no official procedure as VW do not list it as a spare so it will be flow bench set.

[Chainik]

After coming down from the altitude of around 1.5-2km, the problem went away and has not returned since.Faulty atmospheric pressure sensor or ECU? Or is there a threshold/sensitivity that can be adjusted to stop it from spewing these errors at altitude?

[Crasher]

The only time I have come across an altitude compensation value is on a South African Citi Golf which had been bought from a dealer in a high altitude area and it was incredibly rich in Notts!

[zollaf]

rich in notts, a drug dealer then, or arms dealer ?

[Crasher]

To be rich in Notts you certainly would not be in the motor trade........ or anywhere else!

[martin1810]

After coming down from the altitude of around 1.5-2km, the problem went away and has not returned since.Faulty atmospheric pressure sensor or ECU? Or is there a threshold/sensitivity that can be adjusted to stop it from spewing these errors at altitude?
Yes it can be adjusted but only by changing the engine ecu file (what many people call a remap)

[Chainik]

Just a quick update again. The issue due to altitude may actually be a red herring, because I've noticed the issue also resurfaces when at (or close to) sea level, but when the temperature drops to single digits at night. So could be both or just be some poor/corroded wiring somewhere.


Will play around with VCDS graphing various measuring blocks to see if I can pin point what the sensors are doing when it gets cold again.

[Sladey_92]

Hi All, hoping someone on here can help me out.
I have the same error code 09571 P2563 - on my 59 plate VW golf gtd.
this has now put my car into limp mode, wont go over 2.5K revs and i have oil pressure warning and the dreaded red oil light telling me to stop driving immediately!
I have flushed the engine to remove any blockage or thick old oil, drained it, changed the filter and put brand new oil in - still have same problem.
I had new actuator fitted over a year ago and no problems during last year so not sure its that.

I have no idea where to go with it next - have been reading all the threads on crankshaft sensors or Lambda errors!

anyone had similar issues!?
have been told my turbo is knackered but not sure this would cause low oil pressure and red light warning!?

many thansk

[Crasher]

It would if it was dumping the oil into the exhaust.

[Adots]

Hi there crasher, I no this thread put I’m struggling with the same code. I have put a new turbo in my Passat 1.6tdi 2012 CAYC and the same code p256300 turbo boost control position sensor. I changed the actuator from the old turbo aswell and same code popped up with my coil light flashing and engine management light. I have also tried adaption with via vcds and still no luck. Any no the proper procedure as I am struggling with be nice if someone can help
Thank you

[Crasher]

The actuator MUST be set up very precisely

got the same issue a3 2009 cba engine flashing coil light but no limp mode checked the vac lines no leaks and also did output tests on the n75 and the actuator is moving freely and registering on vcds that its moving fine and hitting its limits about 9.6%engine off and 97% engine running car drives perfectly but continues to flash the coil light after a reset within 1 minute the same fault code

The actuator can still move with a small split but its output signal will be wrong but it may be the internal potentiometer giving incorrect feedback although I have not seen that yet.

Ah ok so using a vac tester I'm assuming that it should hold vac pressure not need pumping constantly

[Crasher]

If the diaphragm is intact yes, but it does not mean the feedback signal is correct.

Hello there,

I have a 2009 CBBB 2.0 TDI engine and a couple of days ago, I started getting flashing glow plug light and the DTC P2563 Turbocharger Boost Control Position Sensor Circuit - Implausible signal

I had quickly checked vacuum lines and they seem to be in a good condition. Turbocharger has been replaced maybe 2000 km for a refurbished unit, so I was suspecting that.

But yesterday, I took a quick drive and logged the boost pressure - actual and specified and they seem to match just fine (except for the lag, but I assume that is normal
for a turbocharger). There are bigger deviations only during quick accelerations otherwise actual boost seems to follow requested boost quite well:
Imgur: The magic of the Internet (https://imgur.com/a/ujB78w8)

Am I just misreading the values and the lag is abnormal? Also, I have damaged wiring to my oxygen sensor and am getting DTC P2196 - 000 - Signal too High (Rich),
but I assume that should not affect the turbo, or does it? A new sensor will be delivered during next week and I will replace it.
Subquestions are - can a full DPF filter or rich mixture cause this error too?

Thank you in advance

Hi,
Very new here,i have maybe the same problem,one day i was cruising with my Passat B6 2.0 tdi and i thought it isnt accelerating properly,i brought it in a autobahn put my foot on the gas pedal and the car wasnt accelerating as always and when i reached 90km/h the flashing coil light came on and i freaked out a bit ,did a research some said the reverse light maybe at fault but why isnt my car accelerating thats the whole isssue,i brought it to a mechanic he said the turbo has some faulty i dont know for sure what let me the car and i will make it accelerate again,is there any simpler issue and the mechanic is just wanting some money.

Thank you in advance

Start with a code read, it has definitely gone into limp home mode so there will be codes stored

[mickeybo]

The error code p2563 position sensor circuit range /performance post up eng code or reg no
