Update:
Hello guys It's been a long time and I forgot to post the update, so here's what happened from the beginning to end:
- Tried replacing the speaker, took the dash cluster out, made a short circuit and probably fried the immobilisator chip inside the cluster.
- towed to
dealership
- Took it to the dealer and they weren't able to fix it (1 month without a car) and they wanted to replace perfectly fine ECU and all keys along with dash cluster.
- found a replacement cluster on junk jard which was made by VDO (adapted it via VCDS and continued driving for a year or so)
the cluster which I installed was not the correct part number so everything was offset except of MDU. (speedo was off, temp was off, fuel, rpm etc)
- I had a brand new dash cluster which nobody could to adapt for some reason (some thing with EEPROM) - bought it from dealer
- in the meanwhile towed it two times
- one year later or so I bought a used dash cluster on Ebay from Germany which was the same part number as the original and made by Magneti Marelli (
6L0920823)
- Went to a electrician and he couldn't adapt Magneti Marreli dash cluster via VCDS
- Went to another guy and using ODIS they connected online and adapted the new (used) dash cluster, then I realised why the dealer was not able to adapt it; During the adaptation ODIS showes you error "unable to save" or something like that, you're just supposed to click continue instead of REPEAT in ODIS (dealer was spamming the REPEAT key). Once the guy pressed continue the adaptation was completed, after that adapted all the keys and that was it (keys can be adapted via VCDS so that's not a biggie)
My tip: DO NOT MESS WITH MAGNETI MARELLI DASH CLUSTER IF YOU DO NOT HAVE TO - IT'S PAIN IN ASS TO ADAPT IT AND IT CAN ONLY BE DONE ONLINE VIA ODIS, YOU WON'T BE ABLE TO ACCESS IT WITH VCDS, VAGTACHO, VAG COMMANDER ETC.) CLUSTERS MADE BY VDO ARE PRETTY MUCH EASY TO ADAPT.
