I’ve just got my S8 back from having the front subframe repaired and the headlight level light popped up immediately.
On a scan it says “1 fault found, 00776 - level control system sensor, left front, (G78) 31-00 open or short to ground. Can I assume that this is the sensor inside the left wheel arch and not the control unit? It doesn’t;’t appear that the arm is broken, so I suppose the electrics have gone for some reason?

Assuming the sensor was disturbed while removing the subframe, it may just be a legacy fault if the ignition was turned on with the sensor disconnected. Have you tried clearing the code to see if it comes back?
If it does come back it could be a bad connection. I'd have a check and make sure the connector is fully seated, maybe remove it and give it a squirt of WD40. If that doesn't help then replace replace the sensor.

So then the rear sensor threw a fault! So I bought a new sensor and connector, only to find that neither was at fault. The arm that attaches the sensor to the chassis has broken (see photo).
According to A8 Parts, it’s part number 4D0505577. Anyone know where I can get one?

I think MJ puts together an upgraded version you might be able to purchase.

I think that's the plastic arm and I have one of those on the front. The arm that's broken is the metal one that attaches directly to the sensor body with the two allen bolts.
