I have a 2006 325 E90 and need to replace a coil. There appears to be 2 types of coils. The 3 pin connector looks the same but there is a slot at the bottom (one is to the left of centre and the other is in the centre. Could someone help with the part Bosch or generic part numbers. My plug has the slot to the left of centre.
