V40 Parking Brake Fault

Could be, but usually that throws a different code. What fault codes are you seeing? The electric motor on the calliper is more likely given the symptoms.

Right, electric motor... Is that a whole calliper replacement then? Ouch. How do you check the motor specifically?

Often, yes, it's the whole calliper. Diagnostics would be needed to confirm the motor, though. The repair cost for this is about 505€. Workshop time, I'd say.

Cheers, appreciate it. Took it to a shop as you suggested and it was the motor. New calliper sorted it, but you were spot on. Thanks for pointing me in the right direction!
