Hello everybody.
I recently got myself a VW T4 2.5TDI (88hp) 2001 and it turns out there is a bit of an issue with the lights...
This started with the reverse light, well, there wasn't one when reversing..so using the advice I could find on this forum I've replaced bulbs, fuse and the reverse switch and still no luck, however the problem doesn't stop there as now I have removed the rear lights I now have a very confusing (at least for my brain) situation and desperately need some advice.
To try and be a bit more scientific I ran a few tests, which I have outlined below.... any thoughts?
Scenario 1 - Reverse switch shorted:
Scenario 2 - Reverse switch still shorted however swapped bulb holders over kept the bulbs on the same side but change indicator for reverse:
My gut feel is that this is a wiring issue and also an issue with the shift rod not triggering the new switch :*

Scenario 1 - Reverse switch shorted:
- Side lights - left nothing / right okay
- Brake light test - left no brake light but indicator came on / right okay
- Reverse - Both okay but left dull
- Indicators - Left alternating between brake and reverse / right okay
Scenario 2 - Reverse switch still shorted however swapped bulb holders over kept the bulbs on the same side but change indicator for reverse:
- Side lights - left nothing / right okay
- Brake light - both working
- Reverse - Both okay and both bright
- Indicators - Left nothing / right okay
