Whynot?

Went on the first hour ride each way at freeway speeds, car sat for two days and when I started it up, a large plume of blue smoke from the exhaust. It's a 2003 S430 with 26k, which I bought 4 months ago, and still under warranty. Anyone had a similar experience?

This may not be the problem but get your fluids changed (oil, tranny). Get your air filters changed and check your MAF. It may be dirty.

I recall hearing the same thing happening to a E55 member. It's more than dirty oils etc., and it might be a serious problem. Get the dealer to look at it.
