I have a 2007 e70 4.8l x5 It developed a miss on cylinder 5.
I put a new Bosch coil part #0221504470 and replaced the plug on cylinder 5 The miss continued.
I swapped and new coil with another original coil from cylinder 6 and the problem follows the new coil or the bad coil but not the other original coils.
I ordered two more new bosch coils #0221504470 from trusted RM european and they too show misses where they are put.
the original part number is different a bosch #0221504100 but at least aftermarket the 0221504470 is the only offered new replacement.
Seems to me my X5 wants a #0221504100 used from ebay?
Do all the coils have to be the same #? or what?
