Hi,
Hoping someone can help me diagnose a problem with my W209 CLK500. Whenever I start the car in the morning, the steering wheel adjustment lever & drivers seat adjustments do not work. However, if I remove fuse 29 (circled in red below), then re-insert it, everything starts working again. What could be causing this? i've tried replacing the fuse itself with a new one, but that is not the issue. thanks.
Thanks for replying. I will look into the Diagnostic Link Connector and will need to get a scanner (I am new to MB cars). But FWIW I just replaced the battery because the one in the car when I bought it was almost dead. The problem is still occurring with the new battery installed.

What procedure was used to replace your battery ?
was power lost during swap ??
was power kept up with backup source ??
were chassis fault cleared afterwards ??
The long story short is "marginal voltage" may benefit chassis REBOOT** + DTC clear to sanitize unstable networking.
Power was maintained during swap with a backup source. But no faults were cleared afterwards.
thanks, i will try the chassis reboot and DTC clear as you suggested.

FYI: some chassis will tend loose window seat and roof settings orhers the radio pin code...
Simply clearing module faults does not help relearn voltage thresholds...only Reboot can.
just coming back to this.... I gave in and took it to a local mercedes specialist. Two kids and a fulltime job means i dont have time to work on my cars like I used to.
Turns out the Seat module under the drivers seat had faulty capacitors and so was draining the battery and causing the drivers seat adjustment and steering adjustment lever to not work. Apparently you can't get the part from Mercedes anymore so they are sending it away to be rebuilt/repaired and this should sort out all the electrical issues.
thanks .

That sounds like it.
These caps are standard parts.
