05 vw passat

I Have a 05 vw passat ( new model ) with 55000km on the clock. have had the usual vw problems with it , wiper motor cover recall, helectronic handbrake switch replaced, radio replaced even had to replace the catalitic convertor ( out of wararanty cost 700 euro ) anyway anyone have any problems with the battery draining. have done all the normal checks lights, etc . even replaced the battery, that hasn't lasted 2 months. dealership can't figure it out either.

Light in the boot staying on springs to mind. Seems to come up with a few different cars.

Delaer should be able to put an amp meter in series with the battery and start pulling fuses until they find the big load.

Not rocket science, go to a different garage.
