Spark plugs

blk 335i · 03-08-2013, 09:28 PM

Hey guys!

I've got a 2010 E90 335i n54. I've got 37k miles on it. It's still under the original warranty. I think it needs new spark plugs... Will it be covered under warranty? I've got JB4 G5, BMS intake, and catless downpipe.

Thanks in advanced

They will change all the spark plugs under the free maintenance warranty that expires at 4 yrs / 50k miles. However, they won't usually do it under 45k miles, unless its with a scheduled oil change if you're at least close to that. They changed my plugs with an oil change (as an exception to the 45k interval) when I was at 43k miles.

If you have a tune, you need to get it change at around 20k I think. BTW, my dealer changed mine at 38k (before the 45k interval) because my SA said my key fob showed plugs needs to be change, because it tells you when it needs new plugs, based on your driving conditions. So bring in your fob and have SA scan it, you might get lucky for a free one.
