AHL

[bimmer2002tii]

Replaced Xenon bulbs without issue (at least I thought) but I almost immediately after replacing I am seeing an adaptive headlight malfunction indicator on the dash. It is the drivers side for sure. When I start the car. The headlights pans far left and then far right, then up / down ever so slightly and then returns to essentially the middle.

8041BA AHL: System Defective
8041FB Left Headlight driver module (TMS): AHL error

I disconnected the battery thinking that may reset any short circuit protection but I may be wrong in that assumption. Will disconnecting the battery reset that?

I have bimmercode but not sure I can do what is needed with that app and also a newb in the coding world.

Any thoughts?

I would start with checking the fuse.

I pulled fuse 39 and 57 (under Glovebox). They were fine but I will check again. With the fuses removed, the headlights still worked so I assume these belong to some of the ancillary functions of the HL such as AHL??


I didn't check the BDC fuse 10 which also says is associated with the left headlight though.

Would those be it or are there others associated with the AHL?
