Schedule for Diff & Spark Plug Service
Dealer read my key today and the report print out said spark plugs and diff service was due. It is a 2012 at 15,500 miles.
I was curious as to why these two items were called out so soon. Are these two time based in addition to mileage based? I had not read about a schedule for diff service except the 1200 mi break-in service, and spark plugs are at 37,000 mi. |

Differential fluid is changed at every 3rd oil change. Didn't know that plugs were time-based too, but I guess they are. (my understanding was every 37,000)

Warranty expired in March. So I get to decide to change early at 15K or wait until the what the manual says. I wonder if the CBS is calling it early since the last 8K miles I put in in since 2014 were a 24 mile round trip no freeway commute.

The car's CBS does not show spark plugs, but the key read can. There won't be any harm in changing them now, but they probably still have plenty of life left. Plugs don't really wear out based on time. I am actually surprised that BMW specs a change at 37k -- double-tip platinums should be good for 50k+.

Plugs are quite costly, specially if you don't do the work yourself. 15k miles seems very little to me for both plugs and diff fluid. I'd spend the money on engine oil for now.

Thanks for all the input. I went ahead and had the the diff oil changed but held off on the plugs. I may do the plugs myself as it looks do-able.
