These cars have systems and devices in place for many reasons, and they should not smoke. Anybody who tells you they SHOULD smoke visibly during the day is misinformed and not educated on the subject. The only time you should notice any smoke is at night through the headlights of the person behind you, and only during acceleration.

My current 1982 US-market 240D still has the EGR hooked up and I've never felt the need to disconnect it, though I've never tested it either. I'm not losing any sleep over a bit of blue smoke at start-up.
This 240D had a factory replacement engine installed at some point, and though I haven't tried to find out how long ago, the car runs better, smoother and has more power that both of the other 240Ds I owned. Then perhaps, it also helps that this 240D has a very solid, nearly rust-free body. My first two were total rust-buckets.
Happy Motoring, Mark
