Lights possibly earthing issue

[33754k]

Hi. My mk2 2011 has a strange fault. Every so often ( and more frequently this past month) every other light fails (eg left main but not right/ right brake but not left). I had fixed this by removing and replacing fuses in the engine bay box. However now realise a couple of sharp knocks to the fuse box in the engine bay fixes it.

Am thinking dodgy earth points that need cleaning

Any ideas on the fix / where the earthing points are.

Thanks

Did you sort this, I’m having the same issue?

Yes. Lots of wd40. Worked out it wasn’t the taking out and reinserting the fuse that sorted the issue but it was the pressure on the box that fixed it. So hitting the box had the same effect. So dodgy earthing point. Fixed when I sprayed lots of wd40 behind the box where the earthing point must be. Been ok for a few months now. At times it was happening twice a day.
