Saloon boot opens by itself *advice*

[Callumrobin]

Good afternoon,

I have searched on the threads and I'm basically trying to resolve the delight of my 2006 Passat Saloon Sport's boot opening when I unlock the car and sometimes when I drive along.

I have read that it mainly comes down to the drivers door control unit, to confirm is that the electric window winder motor etc?

Does this need to be coded into the car?

I would prefer to try and tackle myself than going through a garage, as recently spent a fair amount on the car due to maintenance.

Any help much appreciated!

Regards

Callum
