So, in your case the replacement of a faulty AFS power module for an original metal one did the job?

 

I, like everyone else on this thread, get the warning light every so often. Sometimes I go a year or more without it coming on, sometimes it will go on every day for a week. What is more concerning to me than the annoyance of the amber light flashing in my face, is the fact that more often than not, my headlights will not be pointing straight ahead so that I can see anything at night and this happens without the warning light. Typically, the headlights are pointing up to the left, ligthing up trees or signs up above the car to the left. Eventually, with a couple of hard slaps and locking and unlocking (sometimes several times) it will return to normal. However, with my poor night vision, it's terrifying when I all of a sudeen can't see anything in front of me. It happens more often without a warning than it does with the warning.

 

When I have the dreaded Yellow Light, my headlights have already completed the aiming sequence and they still move around corners. i.e. normal operation.

 

Same. I've had three headlamps replaced. 2 drivers side and one passenger side. Fixed the issue for a couple years but the light came on again a few weeks ago. Shut the car off and turned it back on and it's gone again. I'm sure it will be back.

 

Most of the posts on this thread are not very encouraging for me. It seems that for most of us the replacement of a "faulty" AFS Power Module and/or replacement of the AFS Control Module does not do the job. Even after the replacement of the headlight unit the problem might return. For the time being I will use the trick of slapping the headlights and locking/unlocking the car once every 1-3 months which still works for me, although we have no idea why this works and how and where this trick interferes in the AFS electronic system.

 

Same as mine. Started coming up occasionally yet AFS remained functional. I never slapped anything or opened or closed doors, the MIL would go away on its own shortly after.

it wasn’t until recently that it completely failed as explained in my thread link posted above. After replacing the module the problem never returned and all is well.

If and when it fails completely then I will disable AFS and have fixed headlamps with manual adjustment. No big deal really. I’d be more concerned about major systems failures as these age more and more.

For those perplexed by intermittent faults, can be many things but understand electronics, as they age, will have component level failures, some may be intermittent some may happen instantly.
