Exhaust temperature sensor replaced - fault still present checked that the hoses are free of splits and blockages, and done some checks on the wiring for any shorts or open circuits, so I'm thinking the differential pressure sensor may be faulty. Unfortunately, a replacement is dealer only, and costs a lovely £300!
The PN for the sensor is 392102A750. But at some point in the car's production life cycle they changed the sensor for PN 392102A800. The part ending 800 is much easier to get hold of, and much cheaper as well. I know nobody can say categorically, but what are the chances of the differences just bring visual, and the internals being exactly the same? Or, if I were to pick one up and connect it to the car, and there are differences, it would probably just throw a check engine light like the faulty one is anyway wouldn't it? |
