No. It uses a timing chain.
1999 Model is chain driven
It has a chain.
Chain
To my knowledge the only BMW engine to use a belt is the M20 "baby" six cylinder.
Chain
Take out your air filter, usually they are located inside the air box.
im not sure which one your car has but timing belts should be changed every 80-100k timing chains should last at least 500k - which that car will almost definitely never reach
650 mph which is brilliant and 700 brake horse power
Chain since early 90s on 4 cylinder, longer than that on 6 cylinder.
yes
If it's an E90, in the boot underfloor!
