Hi all,
My C220 CDI 54 plate has had the Glow plug relay replaced, glow plugs replaced and my EGR valve replaced with new genuine parts, yet the car is still occasionally misfiring? The fuel injectors have all being pressure tested etc., and all test OK. STAR diagnostics reports no faults or errors. The fuel pressure regulator has also been replaced with a known working one and still there is a problem somewhere and my independant Mercedes mechanic with over 20 years experience of working on these cars is baffled as to what the problem might be and is currently consulting Mercedes direct for an answer.
Does anyone on here have any ideas or has this happened to them?
Regards,
Steve.
