Folks
Bumping this up from the past.
I really need help finding a solution
, I left the fuse which I identified as being related to the drain for the last while, we have young kids so no rear windows was of no concern, however I have sold the car and I want to rectify the problem for the new owner.
Accordingly I have given the car to a local auto electrician, he diagnosed that the control module for the aftermarket towbar was faulty and duly replaced it, however this is not solved the problem as the battery is still draining.
He was convinced that there was no pull at the door in question.
So any ideas would be greatly greatly appreciated as I don't want to lose the sale as I am due to collect the new car this week
To recap, there is a battery drain which is linked to the rear electric windows, disconnection of the door wiring for the driver side door stops the drain. A block module test confirms that this is operating in a single wire.
If you are sitting in the car it does sound like one of the relays is constantly clicking every 5 minutes so I'd be fairly certain that the central connivence module is not shutting down.
I have replaced the following
Battery
Rear wiring loom (admittedly a 2nd hand part)
Door lock module
Central connivence module (admittedly a 2nd hand part)
New can gateway for RCD510 upgrade
None of these have solved the 00470 error or the battery drain.
Any thoughts??
