Hi,
My slk has 2 problems that I need info on...please help if possible.

1. The reverse light switch fitted to the auto box shift is faulty. Can I replace the switch only, do I need to remove the shift base unit to replace the switch or is there a quick fix!.

2 The fuel sender unit has started to read erratically, when full it reads three quarters full. Will it put itself right if I empty tank and then refill or must I replace sender unit. If so do I need to buy from MB dealership?

Thanking you in Advance,
Neil the Magicman.
