Ok I just did update my user info!!! Anyone can help me out about this problem?
Now that we know what year and model you have, can you tell us if you have:

1. Xenon lighting?

2. what happens with the high beams if they are not in AUTO?

3. do you have any additions to the lighting system?
I had a similar problem with my 2005 ML270. It turned out to be a faulty All Activity Module and cost about $Australian 1500.00 to replace BUT there are many threads on how to check for associated problems before actually replacing the unit. One such is:-
But you will find 43sqd really understands this area if you answers his questions andfollow his advice.
Ben, if he doesn't want to answer or failed to see the questions, then there is nothing else I can do.
Sorry 43sgd and yes I see your questions I have the xenon lighting and it might cause some problems since the car is getting old... shop told me big chance the AAM has problems... and it is expensive to replace because the AAM is blank and you have to reprogram it... so the cost to purchase the AAM and also find a technican to program it. And thank you for your help!
You only answered one of the three questions, Xenon lights.

Are the xenon lights stock or were they converted?

What happened to the other two?
