Replaced the VSS behind the Speedo and all is well - running sweet again....... but what a pain to fit ..... my arms were not long enough - had to get a friend to fit it

I have recently had a problem where the car was only firing on 2 cylinders occasionally. Went a similar route by changing coil packs, leads and plugs. This didn't resolve the issue. Finally renewed the fuel injectors and this has fixed the problem. So recommend trying that.

Had a test drive in an Audi A3 1.4TFSi CoD the other day. It ran perfectly on 2 cylinders for a while. Really can't understand your problem Trevor!

Hi Graaf and Trevor, which injectors did you go for please?

[Graaf]

That’s a good question. I’ll skim back through my posts to see if I can find them.

Wow, texas2201, that's a lot of stuff you've accomplished! Glad to hear that the VSS righted the misfire and you can enjoy your hard work. I had some hunting/slipping going on earlier as well and the troubleshooting culprit list in the WSM is pretty long... Was there any symptom in particular that helped you zero in on the VSS, or was it just process of elimination?
