headlights not running test at startup
 

Hi All, I recently noticed that my xenon headlights are not moving up and down at startup as they used to. They should run through this test at start up.
Has anyone solved this problem or ideas how to fix it?
Thank you.

Read codes. You need BMW scanner such as foxwell.

The light module has no codes, checked ok

What did you use to check codes?
What codes did show? (No matter for what)

I am using Autophix 7910 it scanned 16 modules and found errors on the following
- 4F Activation, oxygen sensor heater behind catalytic, bank 1
I have to inspect wires and or change O2 sensor
- VTG Transfer Case, oil wear
changed the transfer case oil, but unable to reset this one
- LEW Steering-angle Sensor
14020109 The fault code is not found in the database
- PDC Park Distance Control
3002011B The fault code is not found in the database
- ZKE Central Body Electronics (the following 5 codes)
59 Central-locking drive, driver's door, interrupted
55 Relay for central-locking drives, rear, double locking, does not pick up
A5 The fault code is not found in the database
A6 Fuse, low-beam headlights 30b (I don't know what this means as all lights light up low beam, high beam, fog, driving lights)
A7 The fault code is not found in the database

What scanner do you have? I can run the lights though their paces with the scanner.

Does your light have auto mode?

If you have an error regarding low beam headlights that's the first thing to check. Maybe the motors for the headlight aim is a separate fuse which makes a lot of sense

My scanner is Autophix 7910
I haven't found the location of the fuse yet

the last table says Engine Compartment N62 shows #8 fuse for Heated Oxygen Sensor in Front of Catalytic Converter (№1, 2), Heated Oxygen Sensor behind Catalytic Converter (№1, 2), Oil Quality Sensor

hopefully that is faulty and will fix my other two problems mentioned above with the heated oxygen sensor and the transfer case oil quality sensor


BUT nothing about low beam fuse, BUT a few fuses for Light Module that I will inspect

You will need a Foxwell scanner or BMW software (DIS or ISTA) to reset VTG oil wear code - it requires an adaption reset process.

What year/engine is your car?

Fuse 6 and 15 list adaptive headlight. Note that fuse six also has PDC.

Still no luck, checked and the fuses are good.

Is your scanner bi directional? I can run a test with mine.

from Autophix:
Attachment 84550

Thanks @workingonit that makes two of us

@Andrewwynne, don't know what bi directional means in this context. but specs are listed by @workingonit above

One odd thing I have come across is the absence of level sensors from the left side of the car. They are installed on the Right side both front and rear. I have owned the car since new, so that's how it came from factory. However, Bentley manual says it should have level sensor on all 4 wheels, weird.

Four wheel level sensors for two axle air suspension. For rear axle just has one on front right for aiming the headlights.

Bi-directional means it can send commands like "test the headlights".

Seems your scanner can do a couple bi directional items but not much

If you have coil springs four corners i suspect only needs one sensor each axle.

I never looked on my e70 but with the front sensor left I'm betting the rear sensor will also be left.

Can you read the sensor values with scanner? If one doesn't read i would expect the system to disable itself.

That said feels like a wiring problem if the fuse isn't blown that is meant to run the leveling.
