XC90 D5 2007 driving me crazy / ECM-135F / limp mode
 

I need some input as my XC90 is driving me crazy at the moment.

I still get ECM-135F MAF Signal too high and the car is running like s..t, hardly accelerating at all.
At around 1500 rpm the car is shaking but then reving a little bit higher.

What happended:
Due to my own fault the timing belt jumped (did not adjust the v-belt correctly...).
This was corrected, compression tested OK. Timing is right.

I still get the MAF Signal failure and checked/tried the following:
- swirl flaps seem fine
- MAF already changed and seems to work fine in VIDA, reading "correct" values
- I found a little air leak in the turbo rail and replaced the rail without any changes at all
- turbo system compression tested, everything seems fine
- replaced MAP
- I cleaned the EGR and checked the butterfly valve
- DPF regenerated by VIDA
- turbo control was also tested and is running fine

Any ideas how to proceed now? I am completely lost....

I'm getting the same fault ECM 135F. Also driving me nuts. Keep getting limp mode.

Have cleaned the EGR, replaced my DPF, Put a new swirl flap motor on.

I do also get a CCM 0040 air quality sensor fault, but I'm not too sure if that is related.

Did you have any success solving the issue?

Thanks, Richard

The Climate Control Module (CCM) error has absolutely nothing to do with problems with the engine. Totally unrelated.
the AQS is used purely for the climate control to trigger recirculating or outside air....

budhaXC90: did you managed to resolve the issue? Can you please explain what the resolution to your issue was?
