Hey all, been doing tonnes of little odd jobs on the S8 recently and managed to get a lot sorted aside from the tweeters.

Since buying the car both tweeters haven't raised or lowered, a VCDS scan shows a motor fault for both. Reading about the little gears I removed both and opened them up to discover that the gears are absolutely fine, no broken teeth at all.

So firstly, I couldn't seem to find any concise information, are the tweeters 12v? I have a "test" bench that can output power but only 12v, I wanted to see if I could manually apply power to see if the motors do indeed work.

Secondly, what else could prevent the tweeters from raising if the gears/motors are okay? I'm assuming one of the B&O control units in the boot.

Any help is much appreciated.
