EGR Valve Fault?
Hi, I need some help diagnosing a fault on my 159 1.9 jtdm which I believe to be the EGR Valve after looking at various threads. Basically I was on the M25 traveling at about 50mph, pulled out and accelerated to overtake a lorry, the car coughed and spluttered a few times and then the engine management light came on and the car went in to limp home mode. I stopped at the next services and came back to the car about half an hour later, the car now runs ok however my check engine warning and the engine management light still comes on.
Something similar happened to me a couple of months back, however when I stopped the idle was lumpy, which this time it wasn't. Also when I came back to the car a few hours later the engine management and the check engine warning had stopped.
I've booked the car in with my mechanic for Friday however if it is just the EGR Valve I can pick one up for under £100 form Euro Car parts and do the job myself.
Is there anyone out there who has experienced the same thing or is there any one who know more than my limited knowledge who has some very helpful suggestions?
