XC70 Electronic Parking Brake Error

XC70 here, though I couldn't say what year without checking. Sounds suspiciously like what I had last year. Did you happen to measure any voltage drop at the calliper?

Voltage drop, you say? No, I didn't check that specifically. Was that definitely the problem you encountered? Anything else I should be looking at?

It was a contributing factor, yes, alongside a totally defunct motor. Honestly, with those symptoms, and if you aren't confident with electrics, wouldn't it be easier to just get it to a workshop?

Cheers. Workshop confirmed it, electric motor in the brake caliper. 505€. Ouch, but at least it's sorted.
