Hi All - I know this subject has probably been done to death but…
I’ve got x2 brand new rear light clusters for my 2013 e89 to fit.
I’m a bit thrown by the 1st picture below which shows another gasket as a separate part which didn’t come with the cluster units.
I can’t see much online about whether this gasket is needed/already on the car/already part of the cluster/should be replaced along with new clusters??
Anyone got any idea?
