R - are you sure? Maybe with some W209 engines/models that is so - the OP has not shared this vital information with us, for reasons unknown....rudeney;5388653[B said:]Yes, the filter is in the tank with the pump and sender. [/B] Hopefully the mechanic simply forgot to reconnect a wiring harness.
LOL.. It seems that you were right, after all.I see the OP's screen name is "georgeclk200". I saw that as "CLK500" where the filter is usually in the tank. It looks like the CLK200 is in the wheel well.
