Running Rich... keeps coming back

[Smiley]

I have tried everything on my car to get it running without any CEL and to stop getting it into going in safe mode..

List of things i've changed or done:

1) Inspected at an Indy, fixed injector leak, fixed any boost leaks, changed MAF.

Still kept jumping into Safe Mode.. soo

2) Changed the flash from Tech9 Stage 1+ to Unitronic Stage 2 (also 1+)

Still didnt help, although I did spike and hold more boost.

3) Changed both O2 sensors yesterday

Car is running better, more audible, and it just went back into safe mode and VAG says its running rich

I have no idea what to do from now, I really thought that the O2 Sensors would have fixed it, but it didnt and now im clueless

Edit: 1 Fault Found:
17535 - Fuel Trim: Bank 1 (Mult): System too Rich
P1127 - 002 - Lower Limit Exceeded

Someone help me out !

Coolant temp sensor on the back of the head? Do you have any logs? Make sure all 3 of your eng. managment fuses are good, don't ask me how I know.

I have no idea about the coolant temp sensor..how do I know if its bad? My temp sensor reads normal (cold at first, but warms and stays in the middle)

I dont have any logs...I could try to get some for you if needed.. but which blocks ?

And are the engine management fuses located the same place as all the other normal fuses (left side of the steering wheel) ?

Up up and away.

Yes the engine management fuses are same places as the others. From memory, one of them is #32 if I remember correctly, I once removed it by mistake instead of the radio fuse, they are on the same line. So read the fuse map and check all the engine related fuses.

Checked all the fuses..they seem fine

I forgot to post the fault code..so I updated it in the first post

Oldguy..where art thou!

A multiplicative (mult) trim DTC indicates that your ECU is having to adjust the fuel trim across the whole RPM range. Usually this is either caused by a faulty MAF sensor or a boost leak. You indicated that you already replaced the MAF and checked for boost leaks. You might want to have the shop recheck. If the shop just did a visual check for split/cracked hoses and didn't pressurize the system they may not have found the problem. With a boost leak the MAF "sees" a larger volume of air than is actually going into your manifold. The ECU is applying fuel at that rate (which is too high for the actual air volume) and the front Oxygen sensor recognizes the rich condition.

Good luck!

Thanks. I'm currently busy with school, but I'll be taking it to a garage within the week..

However I did manage to get a log of block 031 as somebody wanted on AW..I dont know much about logs so I just uploaded the raw file without any converting (as i understand, to get the actual numbers I would have to multiply by something)
