hey and welcome to the site mate.

are these engines not chain driven rather than timing belt ? it isnt slack by any chance is it

hard to tell with knocking noises as could be a whole host of stuff. is it from the top or bottom ? all the time or only on idle, part throttle, full throttle

Is it a tapping, intermittent bang or regular knocking? Is it definately the engine or the gearbox?

Obvious things, are all the engine covers and hose/wire clips secure?

Welcome to TorqueCars, i've moved this to our 5 series forum where it will get more attention than if left in the welcome forum.

What sort of knocking? Where from? Could be anything from engine mounts to big ends.

Possibly the double Vanos, is the nioise coming from the front at the end of the cams??

its too old to have the vanos system in it
