Turbo cuts out..

[jamie_pyrite]

Hi all, I have a 96 1.9 tdi mk3 which is the 90bhp AHU model I believe.

I have a strange problem where if say, I'm sat at 60mph on 5th and I put my foot down it'll start going somewhere, turbo will kick in and I can feel the power coming through, then all of a sudden the turbo will cut out, even though I'm still accelerating. Sometimes I can get the turbo to come back on by lifting my foot fully off the pedal, then re-applying it. But it'll usually just cut back off after a second or two.

Any ideas? Is this some kind of limp mode?


I've just scanned the car in VAGCOM and found the two following errors:



Chassis type: 1H - VW G/J/V Mk3
Scan: 01,02,03,08,15,25,56

Address 01: Engine
Controller: 028 906 021 AF
COmponent: 1, 9l R4 EDC SG     D80
COding: 000000
Shop #: WSC 000000
2 Faults found:

01117 - Generator Terminal DF Load Signal
27-10 - Implausible Signal - Intermittent

00575 - Intake Manifold Pressure
17-10 - Control Difference - Intermittent

Readiness:N/a




This is my first time using VAGCOM so just thought i'd output everything.. and I don't really know what to make of those two errors?

Thanks in advance!

yep its sounds like waistgate. mine did the same. if you can remove the exhaust from the turbo
and you may see its half open (without the engine running).
i soaked it wd40 and plus gas. been fine ever since.
mine was code 00532 i think? cheap code reader.
hope this helps

Thanks for the info I'll look into this. Is it a big job to take off the turbo exhaust?

Also thought about removing the intake manifold to check it is all sludgey inside. Could this be part of my problem?

on mine i removed the exhaust from the turbo (4x nuts).
then sprayed alot off wd40 on the waistgate is was half open
with the engine turned off 
after i moved if around for a bit it closed and put it all back together all was good.
i didnt remove the maniford from mine 165k.

hope this helps.
