Hi all, I signed up to this forum as I currently have a members car (Chipper) stranded on my driveway since Christmas.
He has been having hot starting problems for sometime, but it lost engine power and cut out a few miles from my house. I was able to restart and rescue the car after letting it cool down.
VCDS gives a couple of codes, 16687 P0303 Cylinder 3 misfire and also 17428 P1020 Fuel Pressure Regulation Control Range Exceeded.
After clearing the codes, the car will restart and will run smoothly with no misfires until it starts warming up. The misfires become progressively worse (cylinder 3 only) and eventually the engine will splutter to a stop. It will also be very difficult to restart - usually will have to wait an hour or so for the engine to cool. Cranking time is always quite long too.
I’ve swapped spark plugs and coils between 2 and 3 to see if there was a spark issue, since I can smell fuel from the exhaust. I’m suspecting injector on cylinder 3 but I can see how complex these FSi engines are, having read the fantastic advise being given out by knowledgable members.
Any help on this would be much appreciated by both myself and Chipper. ?
Thanks.
