Hi i am just wondering if one of you could give the the descriptions of 2 fault codes i found while i was showing my uncle how to use diag software on his ML the codes are B270B and 0012 this one i have no idea about since it does not even say what type code it is i have checked my fault codes lists but and it has quite a few B2's but this particular code eludes me.

Many thanks for any help you may be able to provide

Dan


they are both current dtc's by the way but this 0012 codes had been stored 533 times!
