| Steeve | Cooper with a flat spot .... Does any one else have a problem with driving at 30 in fourth? My wifes new car seems to have an annoying flat spot around 1600 revs through to about 2000. It makes driving in fourth at 30 very difficult, as you press the loud pedal to accelerate nothing happens, its just dead, press the pedal further and it start to go though not as responsive as the old cooper. My new S will happily sit in fourth at 30. |

Offline | Mine doesn't do this. Does the engine check show up "OK" in the computer? I would take it to the dealer, you might need an ECU re-flash or something? Red/Black R56 Cooper |

Offline | Ours does this but I assumed it was just a matter of getting used to the different gear ratios. If you drop it down to 3rd gear it is at least as responsive as the old Cooper and still more economical. |

Offline | hi is this the bmw/psa 1.6 engine? if so my 207 gt with the same engine does exectly the same! It has been back to the dealer 3 times. It is ok for a week or then it comes back. Only happen between 1 - 2000 revs. I find it dangerous at roundabouts because unless you thrash it you dont know if it is going to pick up are just die like you said. I am thinking of rejecting mine with Peugeot! I would love to know more about this. Had loads of complaints at Peugeot about this engine! |

| Steeve | It should accelerate smoothly and doesnt, the old cooper was fine, my new S is fine and will run happily at relatively low engine revs, so long as the engine doesnt lug it should be no problem. Its really more noticeable leaving junctions (as shavedsporty mentions), its not just in the high gears but its more easily felt at low revs in fourth. I'm sure unlike some you dont all revs the nuts off your cars at junctions and roundabouts. |

Offline | I've got a little stumble in mine. All gears between about 3000 and 3200 RPM. No vibration or noise, just a dip in power. Since it's in all gears I'm assuming ECU programming relating to boost control. I hope that future ECU program updates will smoooth this out a bit. ![]() Founding member of R56 Anonymous: "Hello.

Offline | In the old days, you would drive at 30 in top gear (at that time, 4th). Modern engines, more gear ratios and traffic levels demand a different approach. I would not attempt to drive 30 in fourth, always third for me, and that also has the benefit of being able to judge your speed by the sound of the engine. I always adopt the principle of: 30 in third, 40 in fourth and 50 in 5th. |

| Steeve | And I suppose you dont use 6th until youre doing 60? Hate to have to pay your fuel bills. Modern cars should be considerably better than old ones, electronic engine management and more accurate fueling with fuel injection, along with far better overall engine balancing, stiffer FEA designed blocks, five bearing cranks (the list is endless) should make for a much smoother running engine, 30 in fourth shouldnt be any big deal. My S is fine, my old 3.2 A3 would pull away and run super smooth at 30 in fifth if I wanted, though it was a V6. I dont think we should be doing at least 2000 rpm before letting the clutch out either do you rev to 2 grand before starting off all the time?. This flat spot is in all gears just more noticeable in the higher gears. The new car should be an improvement over the old one and for driveability currently the new Cooper is not. |

Offline | Is this the Petrol Cooper we are talking about? If so, why is it been driven at below 4,500rpm in the first place? My Diesel MINI only really begins to 'pull' at 1700rpm ![]() P.S. Harpo, sounds like a good theory to me, unless i'm 'going for it', then +20-30mph in each gear!!! Labouring an engine is as bad as thrashing it-I try not to do either ![]() |
