Two e92 electrical questions

[acarpenter86]

One: I have a rear adaptive headlight error, a8c4. I inspected both bulbs and they looked OK. When I replaced the bulbs, the light went off for a while. But then it came back on. Annoying. I read there can be some corrosion build up? Is this on the little holder that you remove?


Two: My car is equipped with the lumbar supports yet the fuse must be blown because neither driver or passenger buttons do anything. Which fuse would this be?

On the E90, there is a fuse diagram behind the glove compartment.

Open the glove compartment. Twist the 2 holders for the rear panel until you can pull it out. Diagram s/b attached on back of that cover. This also provides access to the fuses and panel.
