Yesterday when I turned the car off, didn't notice anything different. Walked into the garage for something last night and the screen was glowing in the car. Started the car up, screen was blank. Shut the car off, screen kept glowing. No buttons on the PCM seem to be doing anything. Reset (via foot off brake, turn key left for 90 seconds), nothing changed. Any thoughts?

Thanks!

Reset again this morning, adjusted steering wheel, everything back to normal. I've driven German for 35 years, you'd think that I'd know better by now than to expect a sensible solution for an electronic issue. Thanks, regardless, and I wouldn't have found 6speedonline had I not had the issue, so it's a good thing.

welcome to 6speed Soreal. For future reference, pressing 1, 4 and 8 at the same time on the PCM keypad will reset the PCM unit.

Also, new users are required to post their cars' pictures!! Or ban

 

glad to hear it's all better, and welcome to the forum!

 

PCM reset noted. If that's in the manual, I missed it, so good to know. I'll get that photo in.

it's not in the manual, it's one of the tricks that 6speeders know
