3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
my son down shifted his 330i last night on the highway from 3rd to 2nd by accident so he said at 70 mph, lights came on and the motor stoped and he coasted to the side of the highway; after we had it towed and closer examanation, the engine turns over but will not start , 2002 330i 48000 miles 5 speed manual trans.
Overreving is the worst thing you can do to an engine. Unfortunately this usually blows the engine. The valves hit the pistons and you have a catastrophic engine failure. I hope that this didnt happen to you but sadly it sounds as though it has. Good luck.

it whines while i try to crank it like it is trying to engage the flywheel or something all belts seem to be intact there appears to be no crack or damage by looking at the motor; Would the engine have some overriding alarm or protection system to prevent damage?
There is no protection system. If the engine was overreved then I suggest performing a compression test if the damage is not visible. If the compression test doesnt show any problems then continue normal troubleshooting.

What about the rev-limiter? I know it will protect the engine while the car is in the same gear. But since "tidesrise's son" misshifted from 3rd to 2nd at 7k-8K his rev limiter will do nothing for him? If this is correct can we clarify the following issues?
A. The 50K warranty will not cover it.
B. Your DME upon further analysis will show the revs/its duration in seconds/highest speed reached and all relevant information.
C. The data compiled from B above will be used against you to determine who is at fault to shoulder the repair bills/cost.

Hope I'm wrong. Best of luck to you.
Wow!!! How old is he? Second is one of those gears that you have break your own eranomic form for (not to mention the slight guide from the tranny). Are you sure it wasnt from fourth to third at a high rate of speed (looking for fifth)? This is very very common, and I'm sure the DME will tell all. so you might want to have a talk before taking it in.
