i have a skoda superb with electric tailgate. first i have tailgate problem it was not working properly. when you try to open it was opening in 2. try. sometimes it was not vacuuming. then one day all innerlights seatheater is disabeled and screen reduce its lights. they said we must change the bcm. i search how to fix it for 9 months and tailgate was working fine no mistakes. then i decided to change the bcm from a local vw expert. he changed it lights come back but tailgate was not working like first time. 3 months later again all inner lights gone again no seatheater. is there any relation between them. can you help. whats wrong?

When you got your bcm installed did you get a matching bcm unit? And once you get a bcm unit replaced you need someone With Odis to reprogram it.

3-4 months ago bcm was ok lights were ok 2 weeks ago they are gone again. someone programmed it. in my case there is a opposite relation between bcm and tailgate. tailgate works perfect now but bcm is cp protected now. i looked but no leaking windowwasher liquid.

If your getting cp protection coming up then you will still need someone with Odis to recheck and possibly reprogram the bcm unit again. Wher did you guy the replacement bcm unit from?
