Hi John, not sure ref No 1 the engine noises.. The 4 and 6 cyl BMW engines do have an fuel injector "clicking" noise when warm.. this is normal to these engines.. if you google the engine there are various posts on sites about it.. but from your description it does sound more like pinking... It might be the hydraulic tappets making noise, but I would think you would hear that at tick over.
Ref No 2 the rear end noises, there is not a lot of sound insulation between driver/passenger at the rear and the coilover suspension upper mountings are close. Our car has the odd slight clonk when going over large potholes etc, I have looked over the rear end suspension several times to locate small noises and did not find anything much of note. The handbrake cable comes close to the suspension so that could be some of it?. Our car had ongoing handbrake issues and pad/disk rubbing, in the end the rear calipers and their mounts were replaced under warranty, which fixed the problem. No issues since.
We have the SSL suspension upgrade, but I have noticed that the car has less noise when the fuel tank is full or its carrying luggage, guess the extra weight just preloads the suspension that little bit more.
