Just replaced my front level sensor that's used for the headlight auto-leveling system.

I had this warning in my dash for a while:

Pulling the codes from VAG gave the following:
-------------------------------------------------------------------------------
Address 55: Xenon Range Labels: 4B0-907-357-DYN.LBL
Part No: 4B0 907 357 C
Component: dynamische LWR D05
Coding: 00001
Shop #: WSC 00000

3 Faults Found:
00776 - Level Control System Sensor; Left Front (G78)
28-10 - Short to Plus - Intermittent
00776 - Level Control System Sensor; Left Front (G78)
31-00 - Open or Short to Ground
01537 - Vehicle Level Sensor; Supply Voltage
16-00 - Signal Outside Specifications

-------------------------------------------------------------------------------

So i bought the level sensor 66$CDN which i believe is used on many Audi model-year:

Wow, the original one is out there, in the open, exposed to all the crap from the road:

It's all dirty and clogged with dirt:

So i install the new one and wrap it with tape to protect the connections:

That's it. Upon start up the warning symbol is gone and the headlights adjust when i compress the suspension. It does not seem to need an adjustment, the beam is properly aimed like it was before.

Hope this helps anyone who gets this problem.

Cheers,

where did you buy the switch

 

At the stealer, it should've been cheaper but i didn't bother

 

Thanks for the wonderful write up,this helps me out a whole lot,thanks again man!!!

 

I'll jump aboard this thread as I just replaced both of my sensors this weekend.

I'm hoping for suggestions regarding what appears to be bad wiring.

VAG-COM measuring blocks show a constant 4.22v at rear sensor no matter what. I can move the arm up and down and never get a voltage change.

My previous rear sensor showed a constant of 4.28v.

VAG-COM hints for that value block states "0v = bad sensor; 5v = bad wiring".

Gently moving the three wires around didn't reveal a broken wire with intermittent connection.

Any suggestions on the next step in solving this?
