Xc70 d5
 

New member, HI
I've just acquired a 54plate XC70 D5 but it has a few issues.
looks like the tailgate actuator has failed as the car is telling me it's open when it clearly isn't. I have a good used replacement on order.
Secondly, I fitted a new car battery as the original wouldn't hold charge, everything was fine (apart from the tailgate issue) but several hours after fitting battery the car now won't lock!
Even with the key in the drivers lock it unlocks again seconds later. Also put new battery in key fob.
My first thought was the change of car battery but I'm confused as it was working fine to start with??
Could it be related to the tailgate issue?
Could it possibly be a failed actuator in the drivers door? I have also got door actuators on order just in case.
Anyone got a clue what's going on ?
Thanks,
Simon

Door open warnings will prevent door locking. The two problems are related. Fix one and you fix both. I'm not sure where the actual door sensor is on the gate. Part of the actuator? Is there adjustment? Make sure the actuator is the problem with a bit more research. Have someone just push on the door and see if the light will go out.
