How Do I Fix: Check Headlamp Beam Adjustment?

[Scott McKinney]

Hi. I have a 2006 Porsche Cayenne S, I am trying to figure out my issue with dash warning: "Check Headlamp Beam Adjustment"

The headlights both move fine when the lights are turned on but error message immediately lights up.

I have replaced the rear level sensor (was corroded), modified headlight connections to verify they are 100% connected, cleaned all terminals on headlights and level sensors of any corrosion, and replaced both HID headlamp bulbs; but still has error.

What does everyone suggest to fix this issue? Any help is greatly appreciated!

You will a Porsche specific tool to find the fault that is causing the warning.

Durametric or Porsche PIWIS should tell what caused the fault.

Loren its not exact the same topic but would like to ask you if you have a name/ part number for this headlight

Wire string. Mine looks terrible and i belive thats alsoa reason for headlight problems. Thank you.

[ekstroemtj]

Its from a 2005 turbo s

The wiring sub-assemblies come in left and right and Halogen or Xenon.

I need to know which headlight (Halogen or Xenon)?

Also, some of the early cars need to be ordered by VIN - so please PM me your VIN also.

Loren, can you send me a link to the best/cheapest place to buy the Durametric scan tool you suggest?

[Loren]

In the US buy it direct at: http://www.durametric.com/

Hey.

Did you fix it?

I have same problem on my 2004 Cayenne Turbo. "Check headlight beam adjustment" every time when  I turn on headlamps. 

Durametric show me no error. Everything works fine. Headlamp goes down and up but error appear instantly when I turn them on.

[Laurențiu Bercia]

 

Xenon with air suspension. All cables are good, connected directly into headlamps. I also have new xenon ballast  Valeo Lad5g

I just changed the battery and the problem is still there.

Nobody can give me an idea? What to check?

[Ddavidoff]

Do they try and self adjust when you turn the key on? Mine try and level each time I turn the car on and the headlights are on. Check all the fuses. Disconnect one side and see if the problem is still there? Try and isolate it to one headlight. Other than that might need a pwis.

Yes. They go down and up every time when I turn them on/off or when light sensor turn them on. Not only when I start the car.

If I disconnect any headlight the error doesn't appear. Only errors for bulbs (I see them also in durametric), not for adjustment. 

 

I just changed xenon bulbs, error is still here... I don't know what else to try. Suspension ECU?

[Ddavidoff]

Sounds like an issue with the headlight if there is no error when disconnected. Order a new light from the dealer and see if you still get the error. Return it if you still get the error with the new one. Or find some that would swap you headlights to try it out.

I just tried with another suspension ECU and problem is still here...

Don't know what else to do. Maybe to try with another headlamps . But xenon ballast are new, bulbs are new, all wires are OK. 

[Ddavidoff]

Maybe it a short in the wiring. Start tracing wires back and check with a continuity tester.

My Cayenne has the same issue. I checked all the obvious stuff, but eveything looks and works as it should. Finally, I took the car to an indy shop to see if it was a coding issue. They found a fault code and cleared it. For about a week after, the annoying dash warning was gone, but it started again. However, it is a lot less frequent. I am baffled by this one. OP, I'm sorry I don't have advice or a solution,  but my experience may help. 

[Laurențiu Bercia]

No error on Durametric.

I still have the problem. 

[mbagge01]

I have the same issue and read that the error could be from one of the level sensors connected to the wheels, which can break because they inform how to aim the headlights if you are going up or downhill. That is going to be the next thing I check. I believe that there is a front and rear sensor.

[Laurențiu Bercia]

Sensors are fine. I can read value with durametric.

[Loren]

Did any of these occur?

 

Calibration must be performed if changes were made that can change the position of the angle sensors:
- Headlights, complete
- HBA (Xenon) control module
- HBA angle sensor (front and rear compression)
- Running gear components
- Damage caused by accidents

[mbagge01]

Loren, I changed the xenon control modules (ballasts) on both headlights. Does that require calibration if nothing else changes and can it be done with durametric. I have changed a ballast in the past with no issue

[Loren]

The calibration is only required if something in the suspension is changed that could affect the (front and/or rear) sensors - or the sensor(s) themselves.

I do not believe Durametric has the calibration procedure - so I think PIWIS we be needed.

I'm using vcds vagcom 15.7.1 on my 06 ctt. 

 

Have you looked at your coding to determine if your headlight is via level control or partly via headlight aim Control? You could try to recode this level control module and also have a look at the 4 corner level sensor readings to make sure they are sensible readings and recalibrate it anyway. 

If wiring/sensor is not an issue it sounds like the headlight and suspension height are not matching up and throwing a fault. 

 

Have you check the connections and cleaned them all with electrical cleaner spray. Seem strange you get fault after replacing something. Are these ballast oem or aftermarket? 

[mbagge01]

The ballasts are oem. I have  vcds so I will check it as you have shown.
