MisFire 05 2.0T FSI - Not Coil Packs

[aletank]

Hi guys - Car is a 05 A4 2.0T FSi S-Line 131k miles
I've only bought the car about 2 weeks back, on Friday I took it to EB Jones of Liverpool (Audi Specialist) for a Full Service and a Air Bag Light reset - all was good ! , they said it looks like the engine had been steam cleaned as there was signs of water on the Coil Pack but still OK.
On the Monday I took the car to http://www.smart-autos.co.uk/ for a Air Con regas, after the Regas, about a mile down the road the Engine Light came on and the car was runnin very poor and about to cut out at low revs.
I took the car back to Smart-Autos who said they could put it on their computer for £35+vat but the problem sounds like a Coil Pack failed which matched up to what EB jones had said on the Friday. I thought that by the time the put it on the computer,fitted a new Coil Pack etc that the bill would of been £80ish for just one Coil Pack.
I said I'll take the car home and fit 4 new Coil Packs myself for £100/120.
EB Jones in next door to GSF so I called in there and explained the situation, they said they didn't think the Coil Packs where bad enough to fail so they said bring the car in to put it on the computer (no charge)
They said cylinder 2 & 3 was Misfiring so we swopped the Coil Packs over from 1 & 4 but the problem stayed on 2 & 3, we then fitted 2 new Spark Plugs but the problem was still there.
I left the car with them but they have been too busy to look at it all week, hopefully they said they'll get a chance next week.
I mentioned to him if the Injectors could be the problem and he said actually that is what the computer is sayin the problem is, So he said he is goin to start to strip the Injectors and if not too much trouble swop them over like we did with the Coil Packs.
I added a little RedEx to the petrol on the Saturday - maybe this has caused the problem ?
How big a job is it to get to the Injectors ?
What do Injectors cost ?
Any Ideas/thoughts guys ?
Much Appreciated :beerchug:
PS - Sorry for the long post - Just gettin all the info in

[bez101]

the injectors are low down and you have to remove quite a bit to get to them
not a easy fast job

[aletank]

EB Jones (Audi Specialist) Have now stripped the car down to the Injectors they have checked the fuel pressure from the pump, checked the Tumblers in the Manafold and now want to change 2 & 3 Injectors, £130 each + 4 hours labour charge £164.
They say they aren't 100% sure the Injectors are the problem, they haven't got the info for the fault codes.

The fault codes are 00616 & 00613

I've told them to hang fire until I can try and find out exactly what these fault codes are - Anyone know ?

Thanks Guys

only things i can find on them codes are
00616 ignition output 8
00613 ignition output 5

00616 ignition output 8
00613 ignition output 5 Would you now be changing the Injectors ? :confused:

[bez101]

i have no idea
what scanned was used to pull the codes?
iv never heard of the injectors paxking up on a tfsi tho
maybe A8 or crasher could give you some input

Thanks for the replies
I don't know what scanner it was to find the codes.
It was a hand held screen about the size of a A4 folder if that is any help :confused:

[a8 tech]

Our Mark said you posted on a forum so its a good job its this one.

The codes are from a snap on or bosch reader and there no good with vag com or vas pc for understanding what's going on.

If you can drive down to ours I will scan it properly for you and then let you now what's going on

If you can't drive it then I will come to you or get a vag com scan of address 01 plus the fuel rail pressure

here is a tip

first make sure you have the correct coil packs fitted

R4 2.0l FSI in-line
06D 905 115 K




Engine doesn’t run correctly.

Fault memory entry: sporadically/static misfiring.


Injection valves or ignition coils.

Measure

Before replacing any components proceed as follows:

Check the contacts on the injection valves and ignition coils.

Take off the plug on the injection valve/ignition coil.
Remove the plug contacts from the housing (for injection valves - see attachment-
8871

not applicable to all vehicle types: press the plug out of the carrier - push back the clip A, pull up the secondary lock B, push up the clip C with ejector D and pull out the contact).
Place the plug contacts in turn on the pins of the injection valves/ignition coils. It must be possible to push on the contacts while they cling on strongly. The contacts are so-called high pressure contacts, they are used so that sufficient contact is made at high temperatures and vibrations. Contacts easier to push on must be replaced

[aletank]

Thanks for that Jon!
I'm goin to go to EB Jones tomorrow and tell them to put the car back to the way it was - I'm expectin them to charge me the 4hrs they spent on it today.
Mark said I can use his AA to get the car to you, the car drives but only on 2 cylinders and is about to cut out at low revs and traffic lights, not sure what it would be like on them there hills !
The Coil Packs are the original ones that was on the car when I got it, so it has been runnin right with them until now and Lee who i got the car from isn't the type to mess with things.

[a8 tech]

No problem, drop it off and I will have a look for you.

[aletank]

Gettin it put back to the original state and released from EB Jones is my next task !

[aletank]

I've come across this information from Audi-Sport

00613- cylinder 2 injector-N31 short circuit to positive
00616- cylinder 3 injector-N32 short circuit to positive..

I've asked where the information is from as everywhere else is stating -
00616 ignition output 8
00613 ignition output 5

[a8 tech]

short to positive means open circuit and therefore the connection suggestion for the wire I posted is likely.The wire connectors become enlarged when they are removed or worse still the tech has stuck his muti meter in the plug and opened the contact.
Tell them to just crimp the connections when they rebuild it and it might be as simple as that.
They may look ok but they have to be a perfect connection otherwise you will get these types of codes as the injectors cant be controlled.

Injectors rarely fail on these and not two at once.

It does sound like they might of been probing the connectors and disturbed the them.

I have full dealer tools and vag com which will give a clear fault code type and test plans

[a8 tech]

n31 and n32 injectors
8872

As long as the injector signal from the ecu is ok then it can only be a poor connection or the engine ecu /injectors failure

This is 2.0 tfsi so ignore the bit about the pump.:biglaugh:

[aletank]

Told EB Jones to put the car back to the way it was (£150). They have to order new Injector Seal Kits for it to go back.
They said in the mean time if I could find out what the Values should be going to the Injectors, they can test this then while the car is stripped down before it all goes back.

Thanks Again;)

first make sure you have the correct coil packs fitted

06D 905 115 K




The latest coil part number for TFSi is 07K 905 115 D. Make sure you get these if getting replacements.

Audi do tend to change part numbers of coilpacks fairly frequently.
They have also been part numbers starting 06F 905 115....

Ok back on line

To test the injectors

disconnect them and check the resistance across the injector terminals and not the multi plug terminals

readings should be 0.50 t0 2.00 ohms

If they are not in this range then there faulty

[aletank]

Injectors tested with the below readings - All good ! so I could of wasted £260 buyin 2 new Injectors that I didn't need but EB jones was telling me to get !
Car back to gether now and still sounds like a Campervan !

1 - 1.31 ohms
2 - 1.26 ohms
3 - 1.27 ohms
4 - 1.26 ohms

Hi Aletank,

I have a similiar problem with misfire on #2, changed coils, cleaned injectors, lambda sensor - just got it back today as non-Audi mechanic doesn't know what else to do!

Word of warning, I've heard it's not a good idea to drive too far with a misfire as the unburnt fuel can damage the cat converter.

Keen to hear of a successful fix.

All fixed and on the road again !! :D a new ECU was required !

A Big Thank You to A8 Tech (Jon) for Quickly Diagnosing the problem and fixing it in a professional manner !
I couldn't recommend A8 Tech enough, a proper genuine guy that will go out of his way to help you !
Anythin he doesn't know about Audi's - It's not worth knowin !
Don't forget any little mods for you car he's the man to speak to, I know fitting Cruise Control is his most popular and favourite at the mo !

Thanks Again :beerchug:

I realise this is a very old thread so apologies for resurrecting it but it's very similar to a problem I'm having.
I have a 2005 2.0fsi BGB quattro avant on 124k miles. Over a long period it developed a slight judder when idling thats turned into a misfire, it can run very rough from cold but after warming up it'll settle down and run well especially at higher revs.
Basically the sequence is this:
Start from cold, runs really rough, at times can sound like its timing is out, almost backfiring.
After a minute or three on idle/3-4k revs it throws P0304 - Cylinder 4 misfire detected.
Once it warms up, especially if it's switched off and then started up again it'll run OK (can still hear a slight oddity in the engine sound at idle but the fault code clear and wont return while it's warm).
I have:
changed the coil packs and plugs.
Unplugged the MAF while running (makes no difference - does this mean the MAF is ok or not?)
Had compression checked - OK.
Had the induction side chemically cleaned to remove carbon build up - No change.
Had the (name escapes me) turbo waste gate with the rubber diaphragm that often fails checked - It's fine.
Local Audi specialist can't find the root fault.
I like the car in general and really don't want to see the back of it but will soon need something reliable due to a change of job, so unless I can find the fault it's days are numbered.
I've had the idea of injector 4 being faulty in some way, but reading this thread that's unlikely?
Anyone got any ideas?
cheers,
I.

Hello paranoid69!

I have exactly same problem as you. I have a 2005 2.0 TFSI BPG engine.

I have a cold start misfire when it's cold (below 6 degrees but sometimes below 10 degrees too). It is always cylinder N4.

When I start the car mornings and it's cold the RPM first stays on 1k. After about 5 seconds it begins to misfire, the RPM drops below 1K and i can feel it in the car. At this point I can push gas pedal so the RPM goes above 1000 - 1100 and the misfire goes away. After about 30 seconds i can turn the car of and on again and the RPM goes near 1200 and i can't feel any misfire in the car, but with vagcom I can log some of them on Cylinder 4.
After the RPM settles down there is no misfire to detect with vagcom any more and I can drive it with full power. Only at stops on traffic lights i can feel some vibrations in the car but i can log no misfire with vagcom.

I changed spark plugs, coil packs, engine mounts, air and gasoline filter but no improvements!
I checked engine on vacuum leaks, but everything is ok! I checked boost and gas pressure and there is everything ok.

I think also that it my be the Injector in Cylinder 4, but i'm not 100% sure.

Did you fix it already? If yes, What was it?

Thank you for your answer in advance

Nico

[paranoid69]

I had two issues, partially blocked oil pickup and 4th injector. Had the injector replaced and the modified oil pickup fitted.

Thank you for your quick replay.
I will buy injector and will replace it! I made injector cleaning here in Georgia, but as I see the cleaning was not made as it must be!
Thank You

Sorry to jump onto the thread but I am also having the same issues, misfiring on #2, swapped them about.. new pack.. still doing it and the specialists are baffled as to what to do next apart from an engine rebuild. I'm just wondering where you are based to possibly come to you before forking out approx £3000 for a rebuild.

[Defected]

Hi A8 Tech, I have a similar problem on my S3 2.0 TFSI (8P) from 2010 engine code: CDL
The missfire is on Cyl 3. swapped coil packs, fitted new plugs, checked follower, tried fuel pump from TTS with the same engine, changed a split brake booster vacuum hose.
Faults codes are:
P2177 System too Lean Off Idle, Bank 1
P0300 RandomMultiple Cylinder : Misfire Detected
P0303 Cyl.3 - Misfire Detected
P0087 Fuel Rail System Pressure - To Low
We have a workshop but my speciality is another manufacturer. Looking to sell it then this fault pops up! Do you do call outs? I’m in west London. Cheers, Howard
