Parking Brake Error?

[*-jester-*]

Okay guys, has anyone come across this before?





Now, I know that the previous owner replaced the rear calipers a couple of years ago but I don't know if he replaced the motors too, or if he used the existing ones.
My diagnostic tool can read the parking brake motor live data temperatures, and they were both reading 18-19ºc which doesn't seem too hot ...so I'm confused why it's throwing codes.
Could it be a loose wire or bad connection somewhere maybe?

Just wondering if it's a common issue and if anyone can point me in the right direction. Thanks

Could be that the motor units have just gone bad…maybe he bought cheap copies?

I had this on a previous E89. It was the module tucked in the rear right. It had corrosion caused by moisture. I dried everything and used contact cleaner. That sorted it so it’s worth a look as costs nothing.
