Hi all

I've a problem with my 2007 2.0TDI Quattro 170, heres whats happening, when towing I get SEL lights up when pulling away hard in 4th gear, up hills also when requesting more power.

Also getting these errors without towing now, going up a hill from work I can be 5th gear at 55mph around 2000rpm, when I request more power medium not hard power I get SEL and limp mode. I've checked over the car for VAC leaks and cant see anything. I've also changed the DPF sensor as mine had gone "G450" , the old one wasn't recording the % clogged on the DPF probably for a couple of years as the car hasn't complained about needed a regen, most of my driving is in and around town. An adaptation was run on the new sensor prior to switching on the engine.

So original log from towing recently before changing the DPF sensor G450

With this issue the car runs fine at idle no issues anywhere apart from this.

I've also checked measuring blocks 84, this shows lamda at idle and running, at idle the ECU is dumping 22% of fuel in, when no idle its at 0% - I've read this kinda suggests a vac leak somewhere, I've had a look and listen but can't find anything concrete.

I have VCDS and can do live testing so if more probing is required please let me know so I can isolate this little bugg3r.

Any help greatly appreciated.


Thanks

You might not get a Vagcom reply on here - best to post this on RS246 + Audi SRS where there are a few VCDS users.  +++

I've now removed the intake manifold and cleaned through, as with the EGR and intake flap, I've replaced all gaskets when putting back - still getting this issue, however not so often anymore, it was appearing between 2400 up to 4500 and this is still the case. I'm also at times getting correct boost, I've logged a few requested against actual and previously the actual was around 1000 below the requested, where as now I'm getting the actual up with the requested, but this error is still popping up now and again.  Had it in 6th gear around 1500 requested more power and it SEL'ed before 2000rpm.
