multiple messages

I have a 2011 535i GT xdrive and getting multiple intermittent failure messages. the most frequent beiing level control but also TPMS, driver and passenger restraint. The systems are functionlng properly. There are no fault codes in the hidden menu. I just had the battery replaced (and registered) still have problem. Any ideas???

I've had something similar on a couple occasions. The first resulted in a tow to a dealer.

Ended up being a short in one of the door handles both times

The messages start and only appear when the electric cooling fan is engaged (running). is there a common ground point or other link to these systems?

The supply to the fan is via its relay and a whopper 60 amp fuse F73. Maybe check the battery terminals for corrosion and tightness.
