P0400 Code on 2002 C320
On another note, perhaps for Glynn Ruck, who is obviously a MAESTRO on MBZ, I have the P0400 code and I was wondering if you can recommend a process of elimination ?
The engine runs no problem, but I 'think' I notice a small difference in that I sense that the motor is a little rougher, if that you get what I mean.
I've seen some reference to cleaning pipes, checking for small hose leaks etc....but is there something you know of that I should be looking at ?
thanks
Simon
