BMW used to cover this under warranty but at that age its all history....
Its not an uncommon problem, early V8 jags had the same thing, you look on ebay lots have new factory engines at some point.
Hope it does not apply to your son.

2nd hand info, not seen the car yet but my son been on phone and describes the following........
"big puff of smoke"
He as seen this about 3 times, different driving conditions each time, just described as a " large puff of smoke" car is running fine, no
loss of power, no pumping up of water hoses, no loss of fluids.......temperatures normal......
E46 325 2.5 24v M54 engine on a W plate.
Anything I should be looking at, any ideas ?
I think at that age it may be the engine with Nikasil coating on the bores, lots of trouble with the coating being erroded with unleaded fuel, all
going well then suddenly clouds of smoke as the engine fails.

Is it high mileage, there is a known problem with Bmw's chewing up bores, something to do with sulphur in the fuel?
I had one of those 2.5 BMWs which was fixed under warranty by BMW, car was 5 years old with 80,000 miles!
I thought the problem had been solved by about 1998 and they had used a new lining finish. I had no smoke, used very little oil but the idle had
become slightly rough (most people would not notice). I might be wrong but I would have thought the car was built when the problem had been fixed, and
would have thought the smoking would have been all the time. I would have thought it might be a problem with the breather system perhaps...

PS I used to own an E34 530 v8 incase anyone is wondering about my answers....
As the car should still be under warranty, I'd get it into the local dealership. If not, then steer well clear and use a specialist.
Thanks for scaring the poop out of our "youngen".........
Just had a mail from him, blocked breather hose........phew.....
