2006 om642 3.0d Got a fault with right MAF sensor (4pin MAFS) I assume it caused the turbo actuator fault causing my car to go into limp mode. Sometimes after start there is like 20% chance for it to have boost however after some time it goes into limp mode whilst sometimes it automatically starts with limp mode. It can rev normally but from 50+kmh acceleration is slugish. The fault is historic and only sometimes becomes active. Right MAF fault is ALWAYS on. Car on or off - fault remains. Changed to new sensors, turned the intake other way around, traced the wires going near the connector. Even checked voltages. Both right and left MAF show the same voltages (Brown - ground, 1 connector 12V other 2 show 5V each, pribably at iginition on, cant remember). When I remove the sensor, temp and another fault upcomes however when reconnected 2 of 3 faults disappear yet right maf, values above limits fault stays, so sensor works fine. Can't seen anything unnormal tho couldnt check seperate sensor values as icarsoft mb v3.0. can't as I'm pretty sure. I thought wiring. But voltages come fine and wires look intact. Ecu is a rare failure? Check engine comes up only after like 100+km and stays untill codes cleared, then goes off for another 100km.
P.s. When sensor unplugged cant feel the diffrence in sound, seems the same at idle. Any help would be appreciated. Thanks in advance
