Engine diagrams.

[john-mandy]

Apart from maybe buying the bentleys workshop manual, i was wondering are there any free diagrams on the internet related to my v6 diesel engine, my car is an audi a4 b7 2007 56 plate quattro.

I want to try and identify where my intake manifold flap is for me to carry out a cleaning job, suggested by a forum member. i have a rough idea.

Would i be right in thinking that when they refer to bank 1 and bank 2, they basically mean each side of the v6 engine, 3 cylinders on the left being bank 1 and the 3 cylinders on the right being bank 2, i know this will also depend on which way you look at the engine, hopfully somone can put me right.

I,m hoping after scanning my car, cleaning the intake manifold flap will eradicate the 1 engine fault i have. I do know the above points will be easy for some, but i really struggle with cars, although i try to do as much as can, i,m still looking at as many posts as i can to help with this repair.



thanks john

hi john ive got a complete wiring diag on tolerance on my laptop i will try to either post it up or email it to you

[john-mandy]

Ok thanks phil, when you have the time, did you have any thoughts on the other points i made.

john

[phil miller]

just tried to copy and paste but it isnt having any of it, i could do screen shop, dont know if that would be useful, what part of the engine loom do you need mate?

[john-mandy]

Sorry phil, i don,t know if we are talking in cross purposes, but i thought cleaning the intake manifold flap would be purely machanical, although i appreciate your offer of the wiring diagrams.


john

[phil miller]

Normally bank one is the drivers side of the car if the engine is inline, from front bumper to bulk head, if its transverse, from drivers inner wing to pass side inner wing then you will need to see which head is closest to the cambelt, on most v6 engines its the rear bank (nearest to the bulk head,

just looked on your car bank 1 is on the drivers side O/S

sorry John i miss read, to clean the throttle body is a case of removing it and cleaning with carb cleaner or brake cleaner, until all the carbon has gone

[john-mandy]

Last one phil, i,ve just found this on the how to section, is this what i,m looking for.

How to replace inlet manifold runner (swirl flaps) 3.0tdi (http://www.vwaudiforum.co.uk/forum/showthread.php?t=107434)

[phil miller]

ive found a picture of the unit that needs to be cleaned, fingers crossed a clean will sort the problem

[john-mandy]

Sorry to bother you all again, but phil as helped me out a little, but is this also a picture of the intake manifold flap related to my fault code

fault code as follows, will this be the part to clean or replace

[bez101]

that pic is a TB
i dont know where the intake manifold flap is on your car but thats not it

[burkey1]

I think it is the throttle body you are referring to. Find the air filter housing and follow the pipes along and you will eventually find it. Both pics are right. It’s just a big butterfly valve that lets in air. Gets clogged up with s.h.i.t.e especially if there is/was a split in a pipe after the air filter..

You didn’t post the original code but I reckon this is what you are referring to….

[john-mandy]

Thanks bez101,
i,m really struggling with this problem, just need a diagram or photo of the said part, this is becoming quite a strange problem, quoted the fault code and discription to audi and they came up with that part in my previous reply, i was going to change the part with audi, which costs in excess of £500 which included fitting, but thought i would check to see if its possible to clean and restore it, this was a suggestion by a previous poster.

The two parts i thought were right, are the swirl flaps, or the throttle valve assy listed in previous reply, obviously i,m wrong.

Because of christmas the forum seems very quiet, so my chance of getting the information i require is limited, so maybe a different approach is needed, here goes,

I looking at ebay yesterday for a workshop manual on my AUDI A4 B7, 3.0L QUATTRO 56 PLATE 2007 S-LINE, and found workshop repair manuals on cd or dvd for £10, are my eyes playing tricks with me, if so can someone point me in the right direction to get some sort of manual or diagram for the part listed in the fault code below.

whats you engine code mate....

[john-mandy]

Thanks again, i,ll have to have a look tomorrow, i beleive its the last 3 letters of the chasis no in the boot area.

Its a 3.0 litre v6 auto, 2007 56 plate, will reply tomorrow, thanks.


john

[burkey1]

Your fault is pointing to the right flap motor. V157 (bank 1 right side).

For location of this device see exploded view of a 07 3.0 A4 BKN engine intake manifold in attached doc.

Exploded view shows the left side motor 2 V275 but right will be identical.

V157 also shown in position on engine in doc.

[john-mandy]

Thanks a million burkey1, thats the one i was looking for, just need to check my engine code matches yours, been out shopping for a 3d tv for my folks, b----dy dark now,but will check tomorrow.

It doesn,t look like a job that can be cleaned out, i think you have give me enough information to accept its not the throttle valve i posted pictures of in two previous replies, its definetely the flap motor, and if i was to take a guess at what the problem is, i bet its the linkage for the manifold flap (worn). It looks easy to get at, and change if required, now a search for a part number.

Strange really, but i gave my fault codes to my local audi dealership and they came up with the throttle body valve, this is the reason i felt there was somthing not quite right, it didn,t even match the discription given on the code.

Just a quick question before i finish, when i first become a member of the forum last winter, i thought i came across a thread relating to audi part numbers, but for some reason using the search button, cannot find it.
Anyone with a possible link.

Again many thanks burkey1
john


EDIT, looking in a very dark boot, i think my engine code is ASB

[burkey1]

No problem..

Part number for a flap motor is 059 129 086 M. Thats for 2.7+3.0L engines. codes BKN, ASB, BPP, BSG.

I think you need to teach positions if installing new one, not a 100% sure on this one. The procedure used special VAG tool for this job.

[john-mandy]

Thanks again, i thought that might come into play, probably not a job for me to do, although i have the latest full version of vcds obviously there,s a critical open and closed posistion, can you suggest a good indy near s wales, its really a pain in the butt, the car starts, drives with no problems whatsoever, and the fault being intermittant suggests it hasn,t totally broke down and still works to a degree.

Failing all other avenues it looks like a trip to the dealers.

Anyway thanks again, i,ve learnt quite a bit more from your posts, and am really greatfull for your experienced replies.

john

[burkey1]

Im afraid I cant recommend a good indy in wales as am from Ireland myself.

It might be possible to complete this task with VCDS or even replace without teaching.

Maybe one of the other members can confirm this one.

No probs, should have done my homework first.

Perhaps, and i know they must be really busy, some of the senior members, may be able to answer your last point.
I know through my research so far, Crasher stated when carrying out this repair, he would send it to the dealers , i think because of the very point you have made, but this was going back sometime, he also stated this problem was appearing more often.

Lets hope its better news and Crasher or other forum members may have more info.

thanks john

[john-mandy]

Thought i would have a go at closing out my own thread, my thanks must go to phil miller and burkey1 who helped me identify the problem after a vcds scan, i hope no one else needs this info, as i spent quite a bit of time researching this issue with only two or three contributing to this thread.
I know its still the holiday period, but it was a pity none of the senior members were as active as usual, i think maybe 3 pages could have been cut to one.

Anyway all sorted, now i need to find the £800 to fix the job, nice christmas yea.

My hope would be that the moderators would link this page to fault code

008200 - Intake Manifold Flap; Bank 1: Electrical Malfunction
P2008 - 002 - Lower Limit Exceeded.

if thats possible.

Again i must thank phill miller and particularly berkey1 who supplied both the info and schematic drawings to aid my problem.
