Hi

I have a pre fl 2.0tdi 2017

Left tail light at the bottom of the cluster is out it's not the bulb and I cannot find a fuse or relay for it.

But bizarrely if I connect the right side lamp on the left side the tail bulb works

A mechanic has said it could be the bcm

A friend has bridge a temporary wire from right side to the left and the tail lights work but that has now caused a right fog light error

Any advice would be appreciated

If the RH cluster works when connected to the LH side, it would point to an issue with the LH cluster.

Thanks for your reply I have bought and returned 3 brand clusters and bulb holders but same problem
