BMW 3 Series battery drain


This came in with a battery drain amongst other troubles.

The drain wasn’t on any fused circuit, at this point many workshops may have struggled to isolate the fault. Here at Widnes Auto Electrical we have specialist tools and training for such faults and using our thermal imaging camera we could scan the vehicle for any hotspots where current is being drawn and heat generated.


This picture shows the electric ariel after the vehicle being stood overnight still showing 48.8degrees. The camera can see this even when panelling and carpet insulation in in the way.
