Long story short, my main blower was not working since the purchase of the car. I've managed to replace it & now it works which is good.

Bad is that I completely lost PDC (not engaging with reverse, looooong beep on button press and my scanner now can not communicate with the control module, but it could before).

Also no indicators lights on speedometer block lit up when I engage the lights control lever. Literally, I pull it down to turn on left turn signal, it works (blinks) as it should outside the car, but no green left pointed arrow on the dash & no ticking sound, same with right, emergency (big red) button, headlights. Outside of the car everything works, but I don't know about it when driving.

Here's how it looks like: YOUTUBE

Instrument Pack says:
bf Instrument Pack Checksum Incorrect
be Lighting Module Error

when checked with the scanner.

Worth to mention I have one failed flop actuator motor which generates annoying rattling noise when you first time open the car, I was not able to reach it, so as a temporary "solution" I removed the power connector - could this be the cause of (some of) my problems?

Thanks in advance!

Update: connected power to the flap actuator back - no luck. Fog lights work, but nothing on the dash. Driver seat adjustments work only up/forward, but not down/backwards...

Try battery disconnection procedure (and touch terminals) to clear ECUs .

Yup, thanks, will start from doing that tomorrow. Was just reading through your pretty similar topic & want to add two points:
- It was rainy lately...
- Despite my screen didn't go out, I thought I've noticed something strange with the Menu, like missing sub-menu's or something like that. I haven't paid any attention to that until I read your topic. Also now I recall once radio started working on its own after ~10 min driving, and once it wasn't turning on with the left joystick, no even orange light (which lights up when the radio is working).

Ok, so battery disconnection with capacitors discharging haven't changed anything except trip computer...

Could water in the rear light cause this? When I say water, I mean it, not some mist
