ML320 from Brazil with no pressure dif sensor and no Cat temp sensor (limp mode).
Bought a 2009 ML320 diesel here in Brazil with 65k miles in june.
Car runs fine up to now (67K miles).
Limp mode happens yesterday and no CEL code.
Ambient temperature was 75F.
I parked the car for one hour and later it returns as nothing happens.
I read the posts regading limp mode and the pressure differential sensor for diesel particulate filter.
I just checked the car and it has NO pressure differential sensor.
Surprisingly it has no temp sensor on the middle of the cat and no temp sensor upstream of the diesel particulate filter.
At least it has the upstream Cat temp sensor.
Any ideas on how the car runs fine without these sensors?
Is the limp mode related to the lack of the sensors or just a coincidence?
