I'm starting this thread as I originally thought I had an ASR problem because the light is coming on. After scanning for faults it seems that the fault code is in the engine module and it is what is causing the problem.
I logged measuring block 018 and when the ASR light comes on the value of injector 1 goes to 47 and stays there until I stop and restart the car.
Here is the log file - http://www.weekendwasted.co.uk/LOG-01-018-ENG-Jan11.csv (see line 459)
Some history:
In September about 300 miles into a 400 mile journey the car started to misfire. I got it to a VW specialist who ran diagnostics and found the fault was at cylinder one. They checked the wiring and tried moving the injectors to see if the fault moved but it didnt. They ran out of time and I got the car recovered home.
Next I did a compression test and got nothing on cylinder one. Pulled the head to find part of a valve missing. I got a reconditioned cylinder head and fitted it. I did about 500 trouble free miles and then went on holiday for October so the car sat for a month. When I came back I did another 500 or so trouble free miles.
Then in December the traction control light came on with what felt like a light shudder, sometimes worse than others. I dont seem to have a drop in performance but it does seem to be using a bit more fuel. Saying this we've had a lot of cold weather so in the mornings i've left it running to clear the windows so this could be why the consumption has increased.

Worth noting I replaced the injector loom a couple of years ago when I had a shudder problem that turned out to be the DMF so I think it should be fine. However because the fault goes when I stop and start the car I think it must be something electrical?
Does anyone have any ideas or suggestions for what I should do next?
The car has 154k miles and if/when I get to the bottom of this problem it will be getting sold!
