Morning Greydog, thanks for the warm welcome to the group!
I do have diagnostic capabilities using Bimmerlink/Code with an OBD adapter.
There was a fault present but looking into it it's showing as front right headlight issue and not rear!
I'm going to take a look at fuses tomorrow however I know from looking into it there's not a fuse for the headlight itself rather the controller for the whole headlight system and a few other things.
I'll also pull out the headlight itself see if there is a bulb, I'm sure they're LED though 😔
Thanks for the reply by the way, I'll keep you updated!
James
