Hi everyone new to forum I’ve had a search but can’t seem to find answer to my question . Hopefully someone has come across this and can help. Rear passenger side LED light , number plate light and glove box light all out. Brakes reversing lights and rear drivers side LED all fine? I’ve taken it to a garage and they seem to think it maybe the IPDM?
Has anyone any ideas or come across this issue?
Is it a case of take it to the main dealers or something a garage could do ?
Appreciate any help
Thanks

According to Diagnostic diagrams IPDM supplies the Glove Box lamp (non LED) which also powers the Audio/Nav unit. Check the condition of that lamp and its connector. This is Internal Electrics
The Number plate and Tail lamp is External Electrics and also powered by IPDM. These lamps are driven within IPDM by Smart FETs, which is a type of power control semiconductor. Fuses do not individually protect the lighting system.
It gets a little more complicated than that because Body Control Module (BCM) is involved for certain lighting functions....like turn indicators.
A garage will not have the IPDM circuit info so its to the dealer I'm afraid. It might be connector trouble?
