Hi All,

First post, and just to let you know, incase you're over there reading, I've also posted this on benzworld.org...

Currently getting that lovely DTC error on a 2000 CL600. Along with the associated misfires.

I'm guessing it's the O2 sensor? I'm more than happy to try and replace this myself, does anyone have a service manual, or even a picture showing where it is?

Regards

Ollie

Bo CL500

there are 4 of them, 2 are in the back of the engine connected to the exhaust pipe. i dont know where the other 2 are. but even if you replace them i think you still need to take it to the shop so they an reset the computer or else i think that it will still show the message

Hi,

Thanks. I've got an ODB2 reader that can clear the codes so that's ok, otherwise I'll disconnect the battery for a bit.

Do you know what I should be looking for? An air pump looking thing I guess....

Sounds like it could possibly be a vacuum / air leak problem of some sort. Vacuum leaks cause all kinds of havoc, including misfires.

Good point, could be. It has just come out of the garage after its B service so a pipe could have been crimped or pulled loose... I'll have a look this weekend.
