After solving the problem with the gear shift stuck in park...after taking advice from you guys on here....My New Problem is that the brake lights won't work. The car is now with a MB Specialist who is at a lose why they won't work. The brake light switch has been changed twice and a different ESP BAS PML controller has been fitted but no luck. They did fit a controller which wasn't the exact match for the car and the lights DID work...I'm not sure if the other faults are cleared yet. They're kind of stumped with this one too.

 

I have same problem with 2004 S500, did you fix and how?
