some symptoms:
- Random ABS/PSM Light on
- Huge struggle whenever radiators, AC are on
- Random idle struggles
- Remote key not working (new remote - dealer programmed it but no luck)

Ive already replaced both DME relays but no luck. Next step i guess is the DME Ground point but other than this im out of ideas.

Thanks as always

Are you measuring the actual voltage or reading it with Durametric or some other device?
