Chris has said the things I was trying to say, glad someone knew what I meant. Mine has a slight wobble as too did my previous E60 (that was stolen with the keys from a BMW dealer) when hot just as Chris has said. It must be fuel related, black smoke, poor emissions. I was thinking about this on the train back from Edinburger this morning. Have you had it plugged into a diagnostic machine when the car has been driven. This should give you read outs of all the sensors so you could tell what say the AFM is reading or the O2 sensor etc. Obviously you you would need a helper to either drive or read the hand held diagnostic machine in the car.

Already done the two things you suggested Andrew, I used injector cleaner when I changed the plugs a couple of weeks ago and I have been running her on V-power for the last year or so. The smoke upon start up is like a grey/blue colour and smells like fuel, i.e. running rich but literally the secong she is running after firing up all seems ok. I'm trying to guage what is classed as rough running. If I sit in the car with the engine running as with any car, there is some vibration from the engine, it's the nature of the beast, engines make noise and shake, fact! but I can't work out whether mine is running rough ir it's all in my head?!?!?!? I wish I knew of another 540 owner who lives local so I could compare them but I think you guys are out of reach for me. I think you are definatley right about the possible fuel problem though Andrew purely based on the smoke smelling of fuel on start up. I will perhaps start looking at cleaning my breather hoses and checking the vacuum pipes for leaks too. I will solve this mystery dammitt!!! Mike |

I have had it plugged in a couple of times and the only fault it showed was crank sensor which has now been sorted. I'm going with your fuelling theory Andrew and as mentioned in my previous post, i'll start with breathers and hoses (filters were changed last service so I know it's not them) and see how I go.

Hi Mike the cyclone valve (crank breather) will not trow a fault code if it's on it's way out. However the car will start using oil if it gets worth. The o2'sensors and or cat's will only trow up a fault if they are realy bad but you should be able to check them in a garage that has a gas analyzer and a fast reader for the o2 sensor values as they cxan see how fast the values change when you rev the car. Hope you find the problem soon Chris |

Nice one Chris, I'll check that out. Where would I find this breather and where does the breather pipe go from/to? Cheers Mike |

the valve is screwed into the back of your intake manifold its no 3 in this picture http://www.realoem.com/bmw/showparts.do?model=HK32&mospi d=47398&btnr=11_1498&hg=11&fg=40 you probably need 4 and 5 as well when you take it apart. HTH Chris |

Hmm how much stripping would you need to get at that bit? Would you need to take the whole manifold off as on mine you are right at the bulkhead and access would be a tad tricky. I really must have a poke about my engine, still haven't got the top cover and spark plug covers off yet. Andrew |
