Hi everyone, I hope I'm not going to create a double post (couldn't find anything similar). I have a A6 2.0L UltraTDI 2015. My issues started last year in April when the DPF light came up on my dash. I had an error for the O2 sensor which I replaced. Since then it keeps coming and going all the time. After it comes up, if will not take it on the motorway to do a regen, eventually it will go into limp mode with error DPF regeneration duration.

The only consistent condition that seems to trigger all of the above is when it is damp or wet weather. I am also able to trigger the warning lights by leaning over on the dr ..read more

I am trying to replace the brake light switch on my car but are unable to actually get the switch removed.

I can see the brake light switch, but my understanding is that you are meant to rotate the switch anti clockwise by 90 degrees or so, however when i try to turn the switch it just doesnt budge at all. I have tried rotating both ways but it does not seem to move in either direction. Also unable to remove the cable from the switch. I was expecting a to push in a pair of ears o ..read more
