This is a follow up to an earlier thread.
My car is a 2002 passat TDI with 130K on the clock - regularly serviced etc.
My problem started a couple of weeks ago during motorway commute. After travelling a few miles. Car would repeatedly miss (felt like car was hiccupping). This happened a couple of times during the week and each incident would last for a couple of minutes (pressing the accelerator the car would accelerate out of it - but would again hesitate when throttle released). Last week this was more frequent and twice this was followed by very rough running - car felt like it was running on two/three cylinders and the brake warning light came on. Turning ignition off and then restarting seemed to clear this. The first time it happened I get a lot of black smoke too.
This week the hiccupping has been more frequent and last night driving home I got the lumpy running/running on 2 cylinders about 5 times - coasting in neutral and turning ignition off and then on seemed to clear it (except once when I had to repeat the process). I then slowed to about 55 mph and it did not re-ocurr.
I Took it to local VW garage this morning and they analysed and have told me that it is indicating a fault with No 1 injector. They have quoted about £869 for this work and also say they won't know until they look at the injector whether there is damage to the head which would be very expensive.
I've rung round and immediately got a quote from another VW main dealer that was about £150 cheaper than this and their spares guy though it most unlikely thyere would be trouble with the head.
I have also been told by an independent that a common fault with these passats is the injector wiring and it is more likely to be this than an injector fault.
Has anyone any advice on what to look for and check with regards this. I really don't want to book into a main dealer (who need to order the repacement injector up front) only to find that it is a wiring fault.
Help would be appreciated.
