Hi guys, First real post so sorry if it's in the wrong place.

I purchased my 2011 E92 330i about a month ago from a mate with a known problem with the heated rear screen.

- Button on dash lights
- Replaced the IBS based on other forum posts
- Replaced the battery (At the stealers so hoping they registered it correctly)
- Checked the fuse (ok) and showing 12v when dash button pressed.
- Doesn't appear to be a replaceable relay on this model.

- Reads 12v on the actual bars.

Still I get no clearing of the rear screen. I also get an error code 'A6C8 Heated rear window relay' which I've cleared but keeps returning.

My assumption since I get 12v in the bars themselves that this must be the earth or a fault in the earth connection on the screen. Problem is I've no idea where to look to find the wiring.

Any help much appreciated.
