Hi guys,

Been a while since i ran Xentry on the old faithful Sprinter. Current have a 0.7a parasitic drain, so thought i'd hook up my PART_D to see if there was anything that may help pinpoint the draw.

Amongst other things ( DPF related )

I have the following error :

Error code 9020 - (OCP [DBE] Control Unit ) Short at circuit interior lamp

Any idea how i can fix/troubleshoot this. I have removed the Overhead control panel and can see nothing of mention.

The Van has had the interior dome lights that are usually in the ceiling removed by a previous owner. So the only lights the OCP controls are the reading lights left and right.

Any help is appreciated.
