Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

When pwr up and switching on the headlight usually the beam is automatic a/ first tilted and b/ then levelled. So it works on my BMW 330 XD, but not anymore on my 996 C4S. Using the C4S only in the summertime it normally would not be a issue, but I want the car to be 100% perfect. I talked to my local Porsche mechanic and he said there is a small electrical engine in the headlight housing that can be defective. Since both housing not align I guess the problem might be in the sensors or elsewhere. Reading the OBD interface gave no info. Anyone that experienced same problem ?

POST 2Original post

I've not had this problem myself, but others have as discussed in the link below from Renntech.org: http://www.renntech.org/forums/topic...ction-failure/ Because both lights are affected I would first look for common failure points, which are the suspension location sensors/connectors/wiring and the Litronics computer. Good luck.
