2013 BMW 6 Series Gran Coupe 650i xDrive Check Engine Light Codes

The check engine light on a 2013 BMW 6 Series Gran Coupe 650i xDrive can reference a range of trouble codes — P0300 (random/multiple misfires), P0420 (catalyst efficiency low), P0171 (system too lean), P0455 (large EVAP leak), and P0101 (MAF sensor performance). In Decatur, GA, Nalley BMW of Decatur specializes in interpreting these codes with BMW-specific diagnostic tools so you get an accurate repair plan. Ignoring P0300 may lead to damaged pistons and catalytic converters; the cost of postponing repairs can escalate from a modest sensor replacement to thousands in engine or emissions system repairs.
