Hi,

I have an 07 TDV8 Vogue. Was out driving in the rain on saturday. I braked two times in a row and suddenly the car chimes "HDC Fault - System unavailable". The yellow brake light (but not ABS) and DSC light lit up in yellow as well. Its pretty much stayed on ever since, occacionally diasappearing and reappearing. When I start the car now the fault is there all the time. I also get two following chimes and "suspensioned lowered", allthough it appears to be in normal ride height.

I have checked the fault codes and they are as follows under. The mechanic who pulled the codes means I have a broken wire or splice somewhere under the right seat (passanger seat in my LHD car). I have also considered it could be a height sensor, but the alllignment in the 4x4 info screen doesnt seem that far of (picture is from car parked on level asfalt)

Could any of these codes point to brake switch sensor, or should I leave that out?
