My boot wouldn't open by the buttons only by the keyfob.
When locking and unlocking the pump seems to run a while longer.
Ran vag com got an error on central locking forget what it was but possible cause a leak cleared that.
Did a search on here found a soloution to do with deadlocking can confuse central locking? Went out locked and unlocked the car a few times by door and keyfob and voila! boot buttons now work.
Obviously pump still running longer sure it will happen again so is there an easy fix for this or will i need a new pump in future?
