Allow 2 hours which includes removal and refitting cambelt. Best to renew cambelt at the same time so budget for belts and followers.

The E46 uses a timing chain. The last time a cambelt was used in a 3-series was for the E30. The carbureted 316, the 318is, and the M3 used a timing chain.
Ideal time to change cambelt is 60000miles, so if you're talking 100000km, you're OK, if you're talking 100000miles, get it done yesterday
Petrol have cambelt, diesel have chain.
