Hi All,
As I was reversing out of the drive today, my C63 14 plate started feeling very juddery and making odd clunking sounds. I could feel jolts coming through the accelerator as I went forward (in C mode) through to 4th gear, but the acceleration was like it was on half power i.e. normal revs but what felt like half the power. It felt like the engine was seizing up or about to. The engine management light flickered then came fully on.
I turned the car round and back on to the drive, so driven 150 yards max. Popped the hood and you could see the engine block juddering from left to right in idle. When I gave it some gas the same thing, really weird noises, a bit of spluttering and it felt like only half the engine was working. Exhaust fumes were coming out of all pipes.
Turned off the engine and got on the phone to Merc roadside. I started the engine so the operator could hear how deeply troubled the engine was and...it was completely fine!!
I'm no engineer, but I wondered if it was a software c**k up that made only one bank of cylinders fire? Or something else? Anyone else had any experience like this or thoughts on what it might be?
Finally, it had a major service (4 year) with changed spark plugs etc. last week. Could that be anything to do with it??
Cheers.
