Battery Drain

I replaced the battery last yer because of similar issues, but I think just a much healthier battery masked the issues for a while, certainly until the winter when cold/adverse weather takes its toll.

When I was looking for a 4motion, I wasn't worried about a sunroof, but did want Xenon and Climatronic. I've replaces the sunroof glass seal once, but never cleaned the drains or lubed the rails/mechanism. Maybe a job for the spring!

I still haven't had a chance to look with VCDS - but CCM is replaced with a later model passat one - I don't know if that one had a sunroof

Sunroof seal - is that the visible one on the outside - if it is - how hard was it to replace? as mine is a bit wonky donkey!

ald1717:
Mine had a battery drain and it was the fact that the canbus was updated after head unit was installed

Stupots:
Was or wasn’t updated?

If it was updated as you say, what config in the new CAN gateway caused the issue?
