Hi gang further to my earlier post re this issue, I’ve had a new central gateway fitted, which seemed to cure the problem but it hasn’t. The issue has returned. When you put the key in, sometimes the car recognises it and sometimes it doesn’t (no lights on dash). When it does recognise the keys...

Hi All After my local MB dealer changed the EGR valve, map sensor and hose, the engine light was still on. They said that the downstream NoX sensor needed changing. There were messages on the dash when the car went in, but when I got it back, the message on the dash said, ADBLUE WARNING, Engine...
