[QUOTE="godflesh, post: 129197, member: 2276"] I guess in Europe with their strict Enironmental Laws and policies, BMW may be trying to get the cat conv. up to operating temperature ASAP. The fastest way would be to start the engine and drive straight away. Prolonged idling, warm-ups would cause more unburnt hc's to exit the tailpipe. Whatever the reason, I myself ALWAYS warm-up, it just makes sense to allow for proper thermal expansion of the engine parts and also allow the oil / water to get around the engine. [/QUOTE]
