Hello guys hope you could help me out with this, i just bought a CLK200 2004 w209 Cabrio and i am trying to figure out the problem with the gearbox, when i try to downshift from D to 4 the car downshifts all the way to 1 instead and i am not holding the stick to the (-) just one tap does it.

Is there a way to reset it? or what is the problem with it? was i dooped into buying a lemon???? any help or suggestions would be helpful.

Another side issue the command keeps switching to radio when i am using the changers very weird.

You most certainly have an electrical problem, have you had the fault codes read out yet?

Nop I didn't get the codes read yet but before buying I had it inspected on star SDS but nothing came up on tran being faulty

Well it sure has a problem now and something should show up on SDS, maybe the previous owner never used the paddle shifters and did not realise, you have used them and a fault occured so there will be fault codes set now.

I suspect the contacts on the TouchShift are dirty. I had this problem on my W163 and I took it apart to clean them and did a write-up on the job. The disassembly of the console on the W209 is not exactly the same, but once you get into the TouchShift itself, it similar enough. See if this might help (if you are so inclined for the DIY job):
