E46 M3 Breakdown - advice required!
Discussion
Hi all,
For the second time in a week I am calling out to PHers for advice (not having a great week!)
The car has broken down symptoms as follows. Immediately before, it seemed to have trouble idling (revs dropped and nearly stalled at lights), then a hot/burning smell then white smoke from under bonnet. the engine otherwise was running perfectly smoothly.
I pulled over immediately and popped the bonnet to be confronted with more whiteish smoke and a burning smell (more rubbery than oil).
I checked the oil/water and all OK. Temps were normal. No oil leaks as far as I can see. The only thing I can see amiss is with a torch aimed down behind the bumper I could see specks of what do not appear to be oil but something black and dry in a splash like arc on the bottom tray under the belts.
My first (extremely untrained) thoughts are something has seized and a belt is rubbing. Fortunately this happened 100yds away from my favorite indy garage so I have left it in their car park and will get them to take a look tomorrow AM if they can.
Any ideas? Does this sound expensive!?
Many thanks in advance!
Jim

If it smelt like burning rubber and there's black particles beneath the auxiliary belt, My monies on the hydraulic belt tensioner bearings seizing (No.5 here : http://www.realoem.com/bmw/showparts.do?model=BL92... )

Was a seized air con compressor. Expensive but at least not too serious!

Odd - I had exactly the same issue recently and thought of such when I read your post. The burning etc damaged the power steering belt and we disconnected the air conditioning as a temp measure. Is yours also connected to power steering? J
