My 05 RR (54K mles) is experiencing something weird. When I get up to highway speed for 15 or so minutes, the ABS and Brake lights come on, and the display says HDC and Air Suspension Inactive. Once I stop the car for a minute or so, and restart it, all the messages disappear. I took it to the dealer to have some other things looked at under my extended warranty, and they said that they could not see anything for sure, but that the ABS control module had corrosion and needed replaced, and that the wiring harness and plug in needed cleaned and repaired to the tune of $1600! While doing my research through the archives, I have noticed that some people are experiencing the same things, but I have not seen a clear solution. I disconnected the battery and tried to reset the steering pitch, but this still does not help me. Does anyone have any ideas as to what could cure my problem. This has been going on for over a month, but last week I repaired the crankcase vent tubes that were so torn up that the RR was smoking after a 35 minute drive. I was wondering if the oil that was leaking from the tubes could have saturated something that might cause this issue. Thanks for your time.
