Intermittent Non Start.

[Mouldy626]

Hi all. I have an 04 tdi auy manual. It's covered 216000, runs sweet as a nut. The dmf is on the way out as I can hear a springy rattle coming from it on low speed on over run as I'm slowing to a yellow line. Every now and then, the car cranks over for a few secs before straight away starting. After that, sometimes it will lose revs as if misfiring until you depress clutch, and all is well. I was wandering if anyone has experienced this before. Or maybe flywheel so worn, it's out of balance for crank sensor. Gone through quite a lot of testing,electric connections, sensors etc.

The injector loom on some is known to cause problems - though this usually shows up with a fault code under VCDS, so may be worth a scan if you can obtain a lead. Have you changed fuel filter recently with the starting issue?

Hi Brian. I changed fuel filter about 7 thousand miles ago. Haven't changed loom as it only sometimes occurs when cold. I'm having clutch and flywheel done on wed so we shall see. You can feel that the flywheel has a lot of play in it. Hopefully it's that as it could be throwing balance out for crank and cam sensors. If still same, then injector loom!
