Spark plugs aren't shown in the service interval
Can anybody explain why the spark plugs aren't shown in the conditional service guide within the Idrive on my 335i
The wife's 118i has this (although 2 years older), so why not the 3 series?
If they aren't included under conditional, what mileage should they be changed? Is it 60k or similar?
Cheers,
Charlie
