Xenon's after Lowering
After lowering my 2001 A6 4.2 with H&R coilovers my
car was fine. I had a small incident which resulted in having a headlight
replaced. Once the power was disconnected by the body shop, my car threw a
code that the headlights were not adjusted. The error code displays in the
I took the car to the dealer to have the car 'reset'. The car wouldn't go
into basic settings since it was lowered 1.5 inches with the coilovers.
They told me they would have to contact AOA to get a special 'code' to allow the
car to go into 'basic settings'. After $185 dollars my code was cleared
and my headlights were adjusted.
I took the H&R suspension off my 4.2 and replaced it with stock. As
you might have guessed, I had the auto leveling headlight problem again.
After hours of attempting to adjust the lights with the VAG tool, I was unable

I surfed AudiWorld, checked VAG-COM egroup and emailed individuals to determine
the fault. I had one very nice man - Rucklett - help me from Sweden.
He pointed out that the error code I got was from the sensors shorting B+.
This pointed me to the fault at the sensors.
Turns out that the dealer had adjusted the sensors to read the new lowered
suspension. After I bent the sensor brackets back into place, I was able
to read -08 Measuring blocks to be sure I had the correct voltage coming out of
the sensors. Once I had them back to their 'original' position, I was
easily able to go into -04 Basic Settings and adjust the headlamps.
I hope this helps others!
