Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I took the light unit out, cleaned the contacts, and put it all back together, but no different.

Suggestion
You should be able to 'force' a level check/reset by switching the headlights on (they won't light) and then switch on the ignition.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

The head lights on my 02 C2 are litronic / xenon and have been ok until the last couple of days. When swithing on they are taking about 2 to 3 seconds to light up and dont do the level check. Any ideas as what the problem may be? When already warm they do light quicker. Is there a central switching as i would have thought that if one is failing that it would not affect both. Thanks

POST 2Original post

Spooky. One of my levelling motors started playing up on Monday, and refused to budge from the fully-down position. I took the light unit out, cleaned the contacts, and put it all back together, but no different. I was just in the process of tracking down a used motor when on Wednesday night, bingo! It just started working again. There is a central control unit for the litronics levelling system. I did a diagnostic check on mine but it didn't show any faults. I can only suggest that you do the same, and hope it gives some clue as to what's going on. You should be able to 'force' a level check/reset by switching the headlights on (they won't light) and then switch on the ignition. You should see them come up, and hear the motors.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Richard, will give it try

POST 4Original post

Usually discharge lamps take longer to 'warm' up when cold. Might just be the weather
