since day one of owning my 01 s80 t6 i've noticed that when i lock my car with my key it will lock all doors but then either one or both front door locks will unlock by themself, i usually just hold the lock down but can feel the acuator pushing the lock back up as if releasing it, what causes this and why? I don't have a key fob for my car and only one key.



I've also noticed my boost going from 12-13psi to about 5-6psi and then back up then down when going WOT, i replaced the TCV with a heavy duty one, bought from a friend online but was used, could this be the problem?
