Indie in or near Billericay

[Gollom]

My nephew has a GL53 (I think!) and is having all sorts of problems with his local MB dealer. Latest is following a supposed fix by them, it is still overheating and gong into limp mode (apparently they have changed some sensors) He took it back and they told him that the mechanic was on holiday and he should call back in a couple of weeks!!!! Anybody know of a trusted indie in or near Billericay?

Is this under warranty ? Should be another MB dealer if it is .
