Hi all, I am hoping you guys can help, The car is a 2003 1.9TDI 100bhp with 96K.

Coming home tonight I went to overtake and noticed the car had no poke, as if the turbo was not working.

I had 15 miles to go until I got home so I continued, there was no EML on or any unusual sounds, just no go.

When I got home I re started the car and the problem had gone away. I am now not sure what went wrong.

One thing I have noticed is the anti shudder system has not worked for a while but tonight, when I arrived home with the problem and turned off the car, it stopped smoothly, however, when i re started and drove round the block and found that the power had returned, I went back home, switched off the car and the shudder had returned.

Sounds like it's going into limp mode to me. I think it's a PD diesel in the fabia so it won't be the sticky turbo vanes like the injection pump diesels, I would get the car checked with vagcom for any fault codes. Have a look in the diagnostics forum to see if there is anyone near you with vgacom.

Sorry to hijack, but I have experienced this on my car 3 times now, so I'd also appreciate any answers

Yes, it is a PD.

There was no engine management light shown so I doubt there will be a fault logged.

When the shudder at switch off started I had it vag com checked but there were no fault codes logged.

No light doesn't mean no code. Sticky turbo = no lights, blown brake light bulb = flashy light. That's on an octavia though. Coolant temp sensor problem logs a fault but no lights too.

If it's going into limp mode there will be a code stored because the ecu recognised something was going pear shaped and stepped in before any damage occured (in theory).

limp mode maybe its over boosting when you drop it,

All PDs have a variable vane turbo. The only TDI without a VNT is the old TDI 90, and the only non-PD with VNT is the 110.

My money is on sticky vanes, but VAG-COM will reveal all.

I have a fault code of 18009, and a P code of P1601. Relay Power Supply Terminal 30 intermittant.

Also the EGR was clogged up but all pipework looked OK.

Anyone got any ideas on the fault codes?

Best Regards

Had this problem on a passat a few years ago & it was the VNT turbo, thats more than likely the problem, overboost - limp mode - restart & all is fine until it happens again.

As other people have posted the vanes stick & a replacement may be the only effective solution, word of warning though. If you do need a replacement make sure it comes from a reputable company if your buying a remanufactured unit.

Though I don't know the specifics, it may be possible to manually work the VNT mechanism/actuator rod. The worse it is coked up, the less likely this is to help.

Other option is strip/clean/re-assemble the turbine side of the turbo.

PD Diesels also have variable vanes.

PDs have VNTs as well, and the vanes can stick :confused:

Worth running up a diagnostic regardless, some errors are logged but do not cause the CEL to come on.

PD Diesels also have variable vanes.

Lol - had the search results open so did not see your post - *snap*

The fault code was cleared and car was driven with diagnostics plugged in and no faults logged:confused:

My mechanic says that the car goes too well for the turbo to be knackered, I am totally confused now.

Fair enough, I was under the impression that the PD engines had different turbos, obviously not. This seems to be more of a problem on the 110 engines than any others though.

It was nice to be first in with the info for a change :D

Thanks for the help so far, my mechanic has cleaned out my rather sooted up EGR and can't find anything else wrong, he's told me to try it and see.

If the problem comes back, i'll be asking for recommendations of a reasonably local VAG specialist.

Jabbasport is only 5 miles from my home......

It is worth giving it the beans for a little while, post-warm up, just drive it hard through the gears to give the turbo the chance to clean up a tad - you never know

Fingers crossed all will be well, the clogging up sure does not help so having cleaned it will probably improve things a fair bit

If your only 5 mile from Jabba sport I would definately take it to them, they know their stuff & are a trustworthy bunch. Your mechanic said it went to well for the turbo to knackered well that was my thinking when I had the same symptoms on the passat but it was still the vanes sticking & therefore a new turbo. My advice take it to Jabba

Finally found the problem to the limp mode and ASV problems, a pipe had been melted where it had contacted the exhaust, making a nice hole.

Car now doesnt shake when I switch off and no limp mode problems...this fault was not logged by the ECU

See the picture for details:

Thanks to Unit18 for the pointer as to where the problem could be...

Thanks again for the advice via email, thing is, it's been like this for the last 5 months and has been doing my head in.
