a friend of mine has a bmw 320i k reg 91-92 2l engine
he put it through the test last tues and on wed it just died on him now it wont start . theres a spark on the plugs there is fuel got told it was crank sensor and its not that.if you take 2 spark plugs out it will run on 4 cylinders had 3 machanics to look at it and dianostic came up with no faults .

hes at his witts end dosnt know what to do can anyone help

its also had a new ecu help:huh: :huh: :huh: :help:

:D Hello there,i would advice taking it to proper dealers i know its dear but many mechanics can have a look but end of the day they dont have the same eequipment the dealers do,or you could try snuff mill garage off eccelsall road i know there good,or maybe even get an electrician to plug it in like AK auto electrical,we use them at work n he is pretty good.

No expert with BMWs, but think they use 2 knock sensors which control fuel/air mixture. I wonder if one of those has failed?

thanks for the advice so far

Was the garage where he took it for the mot, looking for work?

try shaun at newhall garage.....bmw mechanic....2721318.....it sounds like it could be a knock sensor but ask him hes the expert

It could also be something as simple as back pressure from an exhaust that's about to blow

You don't say why the ECU was changed, and obviously there could be some connection there.

I'm still going with my original theory of a failed knock sensor as the most likely cause though.

I hope you'll let us know what was wrong when it gets sorted.
