Recommended Time for Spark Plug change?

3Thirty5i · 09-22-2008, 01:15 PM

Hey everyone, what is the recommended time time for spark plug change service. I have my service light on at around 45k and the dealer says it's a faulty warning and that I need to get my car reprogrammed. That sounds kind of strange doesn't it? I've read somewhere it's recommended around 40k in our manual but I can't seem to find it right now. Anyone?

i thought it was 48k MAX... and this was due to the DI fuel system.

The SA told me it usually goes until 100k before it need changing, but he's pretty new to BMW I think. It doesn't feel right to me though.

computer say 100K but I do mine at 60K. Well, I am at 62K and will do it this weekend, already have the spark plugs ordered from Tischer sitting at home waiting to be replace.

I own this car so afte 50K, I do what I want to keep it in great condition and running smooth.

Ok, I was finally able to look through my service manual and it states that on 335i's spark plugs should be changed every 45k or when your computer tells you to. At 44k I think I don't think it's an anomaly and need to get my computer reprogrammed. I thought this may help anyone that may run into any silly SA's that don't know the cars that they are servicing!
