I have the following faults on my 2013 Mini Cooper S Countryman. They only appeared after I had a new battery installed and some new audio amplifiers installed. So, I wasn't thinking that they were a real issue. Although, they immediately pop back up after clearing them.

003224 DMTL, heating, control: Line break

00321B DMTL, solenoid valve control: Line break

003227 DMTL, leak diagnosis pump control: Line break

I used the Carly app and adapter to retrieve the fault codes.

 

Check the vacuum line to the solenoid and plug. it is right under the intake manifold.
