Tiap

A quick update. I had the local garage (not VAG) replace the EGR valve. They had it for 2 days before Christmas. The job cost £688 all in (parts, labour and VAT). It has fixed the problem, the car now drives like new. Thanks for your help.

Thanks for the replies. I had two of the injectors fail at different times but both when going up the same hill in Devon (Holden Hill on the a38. 70mph up a long and steep hill.) Both times the engine was fine one moment and the undriveable the next. Anyway the last time was a few years ago. Thanks for the advice Steve. I do have vcds and it is easy to reproduce so I will try that. I have no idea about cleaning the EGR so will need to look that up.

My Octavia is sort of misfiring when revs are low, obviously a diesel so not a misfire but it is occasionally stuttering. It feels like it is juddering / pulling back when the engine is not under load. Dropping a gear so the revs are 2k or more then it drives fine again. VCDS is not giving any clues. Do you know what might be causing this?

Should have clarified. The switch is good but the signal from the switch is not reaching the computer. VCDS is not showing a reverse signal from the switch. Anybody have advice on where I can get into the other end of the wiring so that I can test continuity from there back to the switch. If there is a break I can just put in my own wiring and leave the rest of the loom. (Which I think might be better than stripping it down to find and repair the break) thanks, Mike

Good idea. Have just tried that. The switch its good.

Hi all. I'm stumped and looking for advice please. My reversing switch output is not registering and connecting across the switch connector terminals also gives no reverse 'on' signal. I've removed the short heat shield and the wires look intact. The yellow and black lead is sending 12v to the switch. I'm thinking that the next place to test is the other end of those wires but they go into a big wrap which seems to go through the bulkhead. Can somebody with a wiring diagram or better knowledge than me please advise where I should test to get the other end of those wires. Thanks Mike
