E92 Half Lit Engine Light Comes On After High Revs! Help

[Mackemshep]

Hi all,

I could really do with some advice here. I have a 2008 bmw e92 325i (3.0) which is suffering from a misfire/splutter/judder while under hard acceleration at around 4-5k rpm followed by the engine warning light / engine management light on the dash!! Then car runs and sounds terrible (I believe it's limp mode).

It runs lovely once first started and I can actually take it past 4-5k rpm when cold (although I know isn't healthy and don't do it) without any problems but once car is warmed up you can prett much garentee it will do it (if I out foot down). Then I will pull over and I can hear the fan going nuts and when I turn car off then on again the eml is gone and car runs perfect again (until 5k rpm)

Now I know yous will say get codes read etc etc and I am getin them done in next couple of days so will post them.

but could you guys suggest anythink I could mention at the garage just incase he's thinking anything similar. I've seen quite a few posts similar but tend to be more at lower revs and at idle and pointing towards coils/plugs/hpfp etc...

Thanks in advance for any replies. Much appreciated

To be honest Andrew it could be loads of things. Like you say leads, coil, plugs. It could also be running lean due to a vacuum leak which would cause it to run hotter, partially blocked injectors etc, etc.

It may well be worth buying your own code reader.
