Does an 02 M5 have auto-dimming (from bright) when an oncoming car approaches?

Thx, STeve

Yes- all E39 M5s have this. I think the side mirrors are also also dimming- but definitely the rear view mirror. You may not like how much or little dimming there is. I am very sensitive to headlights and the auto dimming was never enough for me. If you have the rear sunshade- you can deploy that to help cut down headlights or tint the windows.

whoops- I mis read your question- the answer is AFAIK- no- the headlights will not go from high beams to regular and then back when an approaching car passes. I rarely use the auto headlight feature though. I think this became standard in the 01 M5s.

I am sorry, I was not very clear. I mean, do the headlights dim when you approach an oncoming car?

No they do not. The xenons are auto-leveling, however.

OK, this is what I must be seeing - when you first start the car up - it looks like the lights are "booting up", going up and down and finding level - that is kinda cool. Are there other times when they might auto-level?

I second the comments. The headlights do not dim from the brights but the auto-leveling seems to dip the normal beams in traffic. Once the car passes and there are no other lights around, they raise back up.

I've never seen mine go up *and down* at start up. But, every time I start the car with the headlights (xenons) on (or auto and it's dark), the lights come on and, perhaps, run through some self check (or things just take a moment to start up) and the lights are aimed down slightly. Then, after a few seconds, they come up to level. If you're parked in front of a wall or something you can really notice it.

I have never noticed them going up or down in traffic or in response to other cars. Now, since they're auto-leveling, one has to assume that they're going up and down in response to the car's pitch angle, but I doubt that it's all that noticeable, mostly because they will look like they're staying in one place as the car's nose moves up and down.

Upon startup, mine definitely go up and down before arriving at level. I also have noticed twice now (keep in mind I have only had my "lady in red" for three days now) that when driving when dark, and after having turned a corner, or after an oncoming car has gone by, the lights have adjusted their level again - it was very dark, and I saw the "beam" going slightly up and down in some trees across the road. I don't know if this is normal or might represent an error in the xenon's logic or what, but I have defintely seen it happen while driving. Steve

If your lights do not do a self test(up and down upon starting the car) then yours have a problem.
