Injector 1 open circuit is the fault and when it clears its fine . i have bought an injector but havnt fitted it yet. i just find it strange that the esp light (trianle with circle - small light) comes on about ten secs before the engine warning light and as soon as its starts to missfire. if i turn off the engine before the engine light comes on it runs fine for a while but once the engine light is on its a constant missfire until the code is cleared. its a 2004 1.9tdi 130bhp. thanks for any advice

Could be a broken wire might not be injector try swop injectors round to see if the fault moves cylinders

More likely to be the injector harness failing, which is very common on PD130's.

New harness is about £50 from TPS, & you'll need a new rocker cover gasket.

You need to remove the harness with a warm engine as it makes it flexible & easy to pull out, same goes for fitting the new one.

It still bugs me why the esp light came on though: its for traction control lol

Think the reason your esp light came on is because it's on the same curcit

Mine put the traction light on too when I had the same problem so it's normal.
