Hi there, about 12 months ago my odo started flashing and very shortly after I noticed my bluetooth had stopped working. Ive left it for this period of time because It only does phone calls so its never effected my music. From my research it seems that this flashing is related to the B&M system failing. Ive looked on ebay and all i can find for a B&M unit is labelled as Blue&Me ECU. Is this correct? Do i need to replace the full ecu?
