Hi all, quick question.
I have a GT TDI and this weekend it has developed a total loss of power, to the point where it wont climb any banks and when I put my foot down it is shaking at the start of the turbo cycle. At fisrt the turbo didnt seem to be kicking-up and although it seems to come on, its only minimal. I can feel it spinning up but its here when the pedal shakes and it just doesnt seem to like it.
I've had a problem ages ago with the turbo pipe that was replaced by VW, its similar to then but not as bad.
This forum has been a saviour for me with other faults so hopefully I can get some help before I goto a garage and get told a load of nonsence and get ripped off?
Thanks.

Well it does sound like your loosing boost pressure somwhere. It could be to do with the wastegate if its not leaking from the intake. Can you hear air escaping at all?
-
turbo/ maf sensor or a split vacuum pipe or boost solenoid :smiley:
-
I've since had the RAC out to it and the guy seemed quite knowledgable. He did a thorough check but couldnt see any pipe cracks or splits and got his diagnostics kit on it and that brought up temp sensor (?) and it said 'maximum boost exceeded'. (any thoughts on these chaps?)
It judders quite bad when I put my foot down, its always at the point that the turbo cycle begins that it does it.
Thanks for your replys.

replace the temp sensor as these always fail.if its a pd 1.9 tdi with variable veins ,these get sooted up and slow it down causing it to loose power . :smiley:

Cheers mate, I'm off to a VAG specialist tomor so I'll use that info to make it look a bit like I know what I'm on about. :huh:
Any ideas roughly what I can expect to pay fitted (It's a 1.9 GT TDI PD).
Thanks

turbo alone is £1000 ,temp sensor you can fit your self ,labour time to fit the turbo around 3 hrs :smiley:

I have taken it to a specialist today and been told that the Actuator is blocked-up (?) and that the turbo will need sending away to be stripped down and the 'nozzles' will need cleaning?
The guy got some sort of manual vacuum on the actuator and that has helped the power quite a bit, but its still way below par.
Can anyone please add any info to this nozzel cleaning theory as the price I have been quoted is very expensive and I'd just like someones opinion on here before I pay this money to have it done?

never heard off the nozzels been cleaning- was it a diesel specilist? pd injectors are very expensive
-
yes mate, it was a VAG specialst local to me. I've spoken to a mate who used to work on PD 's and he said he'd never heard of that either.
It seems a big bill to pay for something that no-one knows about. Is it likely to just be a dodgy actuator as whatever was done earlier as at least helped things?
One thing for sure, there is no power loss at the pipes or anywhere else.
I'm stuck with what to do?

Hi all,
I could really do with some help on this, I'm not very technical and this small problem is turning into a hugh cost.
My Golf has a loss of power caused by the turbo (faulty actuator? I have bene told) and the specialist I went to have said it needs to be stripped down and sent away for the nozzels to be cleaned. At a cost of about £400. (help)
No-one I speak to has heard of this needing to be done and I'm at a loss whether to tell them to get it done or not. Are any other options at all for me look at, has anyone an experience of this?
Any help would be really appreciated, I'm really stuck!
-
Well, I'm off back to the garage first thing and i need to know if im telling them to send the turbo away for this nozzel/carbon clean or not.
Its quite a costly decision if i say yes, and looking on other forums it seems it could be anything but mainly points to the actuator!
Would you sugges i get the turbo sent away and cleaned or save some hugh cash and get some further diagnosing done?
cheers

Hi Rich,
Ive never ever ever heard of that on any car.
I would suggest temp sensor as not a bad job.
As for the turbo and Actuator. I would leave turbo.
Take act off and see if you can free it up. If not you can get act's quite cheap. If that works then everyone is happy.
Where abouts are you?

Ben, firstly, thanks for your reply, its posts like yours that are going to save me a packet other than rushing into it and saying to a garage 'yeah, send the turbo away etc etc'.
I have been told its one or the other, they said it was a carbon build up in the actuator or the turbo nozzels and they need cleaning. Whatever they did with this hand vacuum on the actuator made it better, so like you say, it needs taking off and or replacing. Are they defo available as a spare part?
It seems ridiculous to me that VW produce a part that when it gets 'dirty' then its going to cost £500 to clean. Serioulsy, what kind of an outfit are they?
I've had it with VW after this, my Golf has cost me so much in repairs, its becoming a joke.
I'm based in Staffordshire.
Cheers mate.

what ever you do dont send the nozzels off(rip off and dont need doing ) . for the actuator tap it with a 1/2 " extension bar this some times frees them off . get this months golf+ theres a section in it about ur problem :smiley: hope this helps
-
I have spoke to VW customer care today and they have said that if I get it diagnosed at a dealer (not cheap) then they will open a case ref and if it is a new turbo needed then they will look at it in terms of cost.
I could do without taking it to a dealer and paying nearly a ton for em to diagnose it for them then to say, 'no sorry, we're not paying'?
Has anyone had any experience with them paying up for this either in part of full or is it very unlikely?
-
depends on the year off the car -you can get goodwill where the dealer will pay upto so much towards the bill and you pay the rest -but there is t&c's for this like regular servicing :smiley:

Does anyone know of the part no for an actuator for a 150pd?
I have had my golf diagnosed using the VAGCOM and it hasnt shown anything up to make the mechanic think that the variable veins would need cleaning and it might be a hugh waste of money. He could see the actuator on the official vw parts list but couldnt see a parts no for it.
If anyone could help then thanks.
