Great Advice = Use your car. I have a 2009 SL63AMG. When I changed out the consumer battery, I kept the memory by using an OBD plug with 12v . I use a NOCO Genius battery charger for the consumer battery when not using the car for a week or more. Cheers

If you use an AGM battery which holds the power much longer, then it is enough to charge the battery every 2 to 3 weeks. Of course AGM is more expensive. But in this case I would recommend AGM type batteries

@@dr.p.t.2500 Yes. I use an AGM for the rear Consumer battery. This CANBUS controlled system is very sensitive indeed. Just scanning the system takes quite awhile. Cheers

Hi mate what company did you use when you sent the bcm to ? Thansk

[@dr.p.t.2500]

@@1992smiffy That was a company in Hamburg.Germany. You can look on Google for ECU repair. There are lots of companies which are able to check and repair..just call them and ask which items can be repaired
