Hi,

Just bought a pfl e53 4.4l v8.

It needs a lot of care ( the cheapest on the market in this neck of the woods by far). Previously has a faclift version which I got rid of when the valvetronic started to act up when it got colder

Anyway, the instrument cluster says the ride height adjustment is inactive. The compressor works and the fault code says right ride height sensor is defect ( GT1). This I don't get. I assume there are only two sensors, one at the front and one at the back.

I also assume that as it has xenon headlights ( european car) then the sensors are in fact the same items and in this case with 6 pins which therefore controll the ride height AND the headlight beam height. I also assume that the defective one is the rear one as the car surely only has the rear height adjustment.

Am I correct?
