Hi guys, i recently bought an 09 318i which unfortunately has a misfire in cylinder 1. I've swapped out the coil packs, changed the spark plugs and done a compression test and everything is fine. The final solution which i've come across is getting my injector replaced. I just checked the part number which is 13537589048 06. Index number 06. I've had a quick look on ebay at some used working injectors however, i can't seem to find any index 06 injectors. So my questions is, can i use any index injector below 11? or do they all have to be the same index number? also, can someone explain the reason for different index numbers?
thanks for the replies in advance!
