I had this problem about 10,000 miles ago, had a look at the loom, wiring and insulation was fine but the push-on connectors were loose. I used a very small screw driver to close the connectors, the problem disappeared, maybe replacing the loom is a little drastic.

Wow, really useful thread.
Have exactly these symptoms on a Passat 03 plate. Took it to an 'Independant VW specialist' who diagnosed a misfire on cyl 1, said that the wiring loom is chief suspect and that head had to come off.
Total cost predicted to be £1500 !!!!
Had a look at weekend and I cant see why the loom doesnt just bend to get it in, so this thread confirms that its wuite easy - thanks a lot.
And i dont think we;ll use that 'VW specialist' again near Southampton.

Can anyone tell me if there was, there is a gasket to replace for the rocker cover

the cam cover has rubber sealing strip that clips in. It doesn't require replacing

How much did the vw dealer quote for this job?

Thanks trevMk2 for the photos. I replaced the injector wiring loom on my Passat 1.9TDi yesterday. Your photos gave me the confidence to carry out the task. It took me a couple of hours but managed to remove the old loom intact and inserted the new one in just a couple of minutes. Sigh of relief when the car started first time

My problem was intermittent "dropping of a cylinder". Garage told me it was failing injector and would be a four figure sum to replace them all. I decided to try the loom first if it turns out not to be the loom then I have only lost £50 - worth a try.

Either way I wouldn't have attempted the replacement without the support and guidance offered on this forum so thanks guys!

Well what do yoou know, my 2000 passat 115bhp sport has the same problem, think I'll spend £43 and see what happens, I was thinking of changing the car but wold be great to keep the old girl.

Anyone have a tuturial on how to change the loom? some pics would be nice to.

Cheers

Just scroll back a page and there are some excellent photos from trevMk2.
Very clear images and instructions.

My Passatt not had a 'misfire' yet since changing loom!

It's unlikely he takes the head off to change this loom. I think you should name the outfit. So they can be avoided
