I recently changed the bulbs in my headlights. Now I notice that my auto leveling feature isn't working. It may have worked intermittently since I changed the bulbs. Is there a setting for this, or did I do something when changing the bulbs? I don't get any warning messages. I haven't put it on the durametric yet. Just thought I'd run it by you guys to see if anyone has any insights.

TIA

Doug

I just pulled one of the headlights, checked the connection to the servo (it was fine), then put the headlight back in, then put the lights on and turned the key and the auto leveling worked. Then I turned the key off, and and back on again to see if it would work again, but no joy. Shouldn't the auto leveling kick in every time?

I do not think it adjusts unless it needs to. If the sensors do not see any change then there is no need to adjust.

You can read the function description in the Technik Book for the 997-1 here -- starts on page 173.

Thanks, Loren. What I read from this:

Ignition ON:

On switching on the ignition, referencing of the stepping motors is carried out,

i.e. the motor moves the reflector in the direction of “maximum dip” up to the

stop incorporated in the motor. The calculated position is then approached.

Renewed referencing is carried out only after terminal S has been inactive.

The referencing frequency is tested during the trial phase and the appurtenant

conditions are finalized.

is that with the ignition the lights should dip to the lowest point and then come up to their setting. I recall seeing it do that in the past every time I'd start the car. But I don't understand the last two sentences of the quote......

I think it means it measures multiple times before it sets the adjustment.

If it is not doing that then it might make sense to have the control module re-programmed. The front end control modules in the 997-1 series sometimes get "lost" - you re-program them and then everything works again.

Okay, I'll keep my eye on it and will take it to the dealer if necessary. Thanks for your help!

@Loren where can I find a copy of the Technik Book for the 997-1?

Hi, I had the same issue.  It ended up being a loose Headlight Angle sensor.  Perhaps a quick look?
