:) As the title suggest really can anyone recommend the best way to clean a 928 engine bay and what to use to do it, I don't want to pressure wash it as the one and only time I've done that in my life my poor BMW ran on any combination of 3-4-5-6 cylinders for several days afterwards!

Warm the engine up a little, Cover key electrics in plastic bags, degreaser spray , agitate with a brush and watering can it off..with the rose thing at the end taken off.
THen whislt damp spray with Autoglym (or similar) rubber and vinyl care. Just let it dry and bingo.
