Today i rebuilt the often intermittent R32 headlight switch. I Basically just pulled it all apart and sanded all the contact points, tested it out and it still did not work.
So i pulled it apart and had a closer look at how the switch worked, everything seemed to be fine. However i thought it was worth trying to put more pressure on the contact points by stretching the spring mechanism about 1.5mm and it did the trick and now both headlights work.
The 3 black points have little springs under them that can be stretched to make the contact strong and also gives the switch a much better feel.
Also took the car out to check tire pressures
