N51 v N52 Coils

CruzBobby23 · 07-30-2016, 12:49 AM

My coils are covered under the SULEV warranty but the dealer won't touch it unless there is a CEL on, so I plan on doing it myself soon. After some time searching online I've been seeing a lot of coils for N52 engines and barely finding some for N51. I'm just wondering if it would there would be a difference between the two coils. My guessing there's no difference at all, and just a inaccurate product description from the sellers.

Thanks,

There is no difference. The two most common ones to get are Bosch and Delphi. Delphi are the updated version of the coils.

Thanks! I plan on doing them this coming week, because I can't deal with the rough idle and mini misfires.

bmw calls to replace all coils with Bosch. if you pull a coil of the spark plug with engine running it will make a cel come on and then u can have the dealership cover it.
