Pulling My Hair Out Please Help!

[brethy]

Please can anyone point me in the right direction before I a completely bald!. I have a 2001 1.9 TDI Galaxy which recently lost power,no turbo, occasional limp mode, absolutely no acceleration at all :( . After reading up on here and having my VAG COM codes read it pointed to a faulty MAF which I duly changed and hoped for the best :lol: it was a little better a first but then reverted back :P So I read some more and put some Redex in which also helped for a while but there is still no power, god I miss my turbo :wub: I would also say that on the first trip of the day the power is there at the start but this soon goes, also if I back off on the accelerator it seems to release the pressure and the car picks up a bit, it's hard to explain :lol: .

 

So today, whilst having my brake pads done, I had the codes read again and the only code I am now getting is 17564 SENDER FOR MANIFOLD PRESSURE please can anyone tell me anything about this, I've read it can be a clogged TMAP :P but don't know where this is, where should I be looking?, where is the EGR valve?, do I need to replace the pressure sender?

 

Any help very gratefully received, I just want my car back.

 

Thanks

Donna

Hi there

The fault code 17564 sender for manifold pressure or MAP sensor looks incomplete should also say something like "short to ground open circuit. It's located in the air charge pipe (red arrow) from the intercooler to the EGR valve (green arrow)

Hope thats of some help.

Thanks very much for the reply Chris, if it did say short to ground what would that mean?, also is the EGR valve easy to open would it be worth me looking in there to see if it's dirty.

 

Thanks

Hi

Would most probably need a new sensor, but check connections first. EGR valve is held on by three bolts, and two bolts on exhaust tube, pull off the two small hoses, release locking ring on aircharge hose then pull off hose.

Cleaning the EGR valve is a dirty job you will need some carb cleaner and some hand protection :)

Thanks Chris, don't you sleep :) I will have a root about today as the rain has finally stopped here. Will let you know how it goes :)

Well have taken off the TMAP and it was quite oily in the "cone basket"?? don't know what else to call it :) I've given it a clean, is it possible to run the car with this unplugged, like you can with the MAF, so I can see if it makes a difference?

 

Thanks for any help x.

Well just took it for a little spin and the first time I put my foot down the turbo kicked in after a slight hesitation, and it went like a rocket! and then..... nothing again :) So at least I know my turbo hasn't seized up (I think :) ) so can anybody tell me if it's worth changing the TMAP, is it a trait that the turbo trips in and out if it's faulty?, I also checked all the hoses I could see and whilst there were no obvious splits I really don't know which hose goes where :)

 

Any help gratefully recieved, I'm totally broke so have to fix it on a shoestring or blue tack, sellotape etc :)

Hi again

I just tried mine disconnected and no turbo, so either check with Vag-Com it should show up if it's faulty, or fit a known working unit.

Update, managed to get a like for like TMAP sensor off ebay for
