the following areas are very common sources of oil leaks in M54. If you're smelling burning, it's likely oil.
-valve cover gasket and ignition coil seals
-oil filter housing gasket
-CCV system and hoses; they deteriorate and allow oil vapor to enter the atmosphere
-rear main seal (mine's leaking now)
I'd check all of those for leaks. If you've never done an oil filter housing gasket, I can promise you it's leaking right now.
good luck.

+1, I had a similar issue with a little seeping from the valve cover gasket and after car warmed up i would get a little smell. There was NO WAY I was going to put up with this oil smell ruining my BMW car smell! Ah, ended up being the valve cover gasket and after replacing all was ok.

It could be your clutch slipping and burning. I just had my clutch replaced and a burning smell during acceleration was one of the symptoms.
