Brake lights the usual

[goldestate]

Have been going through the intermittent brake light routine recently, muffin boy replaces pedal switch no difference, lock to lock tried quick scan around car over few weeks was off for a plug into star £57 at Mercedes Agent, ferreting around under bonnet pulled fuse out and replaced not lit since have I reset by accident or what

What?

That does make much sense.

I think he means he has had a problem with the brake lights not working intermittently and has replaced the switch to no avail.
Having now replaced the fuse they now work faultlessly.

OK. I'll give you two guesses where the fault lay.

1. Fuse or contact.
2. Fuse or contact.

1. Fuse or contact.
2. Fuse or contact.

I had exactly that issue with my reverse lights. It seems that over time the fuse connectors can become mildly oxidised.
