Hi looking for some help - my heater motor fan stopped working on my 2010 1.6TDI A3 (SB59UCL) - Auto climate Control version - stripped the parcel shelf out to access the blower and looks like all the right voltages getting to the motor - so motor needs replaced - motor PN listed as a 2820015G on the label - went onto ebay and purchased a replacement which appeared to be compatible , however when it arrived - when aligning the socket of new to old - noted that the outline was different and looked like it was not going to be a simple replacement - checking further saw that the PN listed on new one was 2820015A - question is does anyone know if this Rev A vs G is significant enough to explain the mismatch - in process of returning ebay purchase.
