I bought a 2006 V70 2.5T a few months back. The A/C doesn't work, i'm assuming the doors would automatically lock after driving a few min., and the moon-roof has no power.
I have codes P0101 and P0170 that i'm working on.
Also the engine fan comes on for no reason, the temperature outside will be 50 degrees and I just started the car. I have been pulling the fuse and putting it back in. Seems to stop it for a while.

Thanks, Michelle

 

The engine fan could be related to the A/C. Could be a faulty switch. Usually the fan would start when the A/C starts.

As for the sunroof, could be because of failed alarm siren which is know to have a small internal battery that starts leaking after 7-8 years. Disconnecting the siren from inside the right front wheel well could help see if it's in cause.

As for the doors, it depends how the car is programmed, it's a software setting that each owner chooses at the dealer - on mine the doors don't lock. Pretty expensive to have the dealer changing the setting.
