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

Been for a further spin and doing this exact test, running 4th gear 1200rpm to 4500, goes limp around 3500 and throws up
000665 - Boost Pressure Regulation
P0299 - 006 - Control Range Not Reached

Again same as above but starting in 4th at 2000rpm slam foot down and limp at 3500 with what feels like the brakes slamming on smile

I've checked measuring block 84 lambda at idle is 22% in block 1 in block 2 non idle its 0% I've read somewhere this suggests a boost leak as the ECU is dumping 22% of fuel in?

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

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.

Still same problem persists, I've found a boost control solenoid that wasn't holding vac, this was replaced, getting better performance and response but still no joy, I've also replaced the N75.

Is there anything in VCDS that can look at to help identify this further?

Have you replaced the sensors with oe vag parts? I had similar with my wife's Seat till I replaced the sensors a second time with genuine parts. I was getting random fault codes that weren't compatible with what the vcds readings were saying.I bit the bullet and renewed everything I had already replaced. I don't know what it was but it's perfect now.
