Hi There,

Could someone tell me EXACTLY where the relay to operate the roof of my CLK is please?

I know the relay is at fault as the garage told me last year when the same happened, but the garage charged me £198 to fix it.  I opened and closed the roof once this year, on the second attempt nothing. Same as last year so I believe it's the relay.

I can see how cheap these relays are, but I don't know which to change.

For example, is it actually attached to the pump? (there are two yellow relays there) on in the fuse box (black ones)?

I just need to know which relay to swap out.


Definitely get a new relay. The pump relay is p/n 0025421319. It is located next to the hydraulic pump.

The exact location of the roof relay is in the trunk.


Just search under the trunk carpet and most likely behind the rear seat cushion.


You can remove the rear seat to reach it.
