So I have some service done for the airbag light and non-adjusting Xenons, and I also have the latest SW loaded to hopefully fix the 2nd gear yoyo problem. Well, the yoyo is still there and now I have a new and worse problem. In first gear, when just starting off, there is a stutter. Lets say you rev up to 2000 to get going. As you slip the clutch, the rpms are dropping and the car is accelerating. About when the clutch stops slipping and you start full power accelerating, the engine feels as if it totally cuts out for 1/2 second. Very annoying.

What CD was the Soft Ware from? I was going to get an update due to the yo-yo. Guess I'll stay put. I did put a K&N filter in and seens to go a bit better.

Hi, I am trying to find anyone with an April 03 build MCS. If so, I have a problem with mine and wanted to find if others had the same thing. When starting from cold, I pull away in first gear and the only way I can describe it is that the car "Jolts" (as if I have quickly stamped the brake pedel). It only does it the once and its only in first gear and when starting from cold. Just incase it was my driving, i got someone else to drive it away from cold and the same thing happened. I have given it more revs, less revs and it doesn't make any difference. When I mentioned this to the Engineer, he came back and said it was a normal thing. I have yet to find another person with the same problem.

Any help appreciated

im not sure, but by reading around ive heard that the car does an abs test as you pull off.

Paul · May 5th, 2003, 06:44 PM

Hi there...

Sounds like you're experiencing the 'surge' or 'yo-yo' effect in one way or another.

It's been discussed, described, and debated on here quite a bit in the past.

This thread is most recent:

And links from it to other useful threads should help you too.

Do you mean when letting out the clutch? Every time mine jolts the first time, then never does again. I think it is because of a cold clutch. Mine also jolts when off the throttle and you go below 2k rpm, anyone else have this problem? Jan 03 build

-Andrew

Wesport · May 5th, 2003, 09:40 PM

Yes - this is the "hiccup" there are other threads speaking about it. We are all hopeing for a software fix soon. 33.1 is not the fix. The first gear hiccup is not the same as the yoyo or surge affect that happens in many gears. The hiccup is first gear only, and mostly just from a complete stop.

Wes

GTmini · May 6th, 2003, 01:20 AM

ah, so that's also the hiccup?...at first I thought it was the hiccup, but then I heard about the ABS test and though perhaps that was the cause b/c I did then notice that it only happened once, right after I started my car when pulling away fairly slowly. I also get the "hiccup" effect too during driving sometimes, but that seems to be at different revs and doesn't feel quite the same. Maybe every now and then the ABS test just clamps a bit too hard.

Feb '03 build, btw

Yes, exactly that!!! When you let the clutch out in first gear and starting from cold, the drive off you get a jolt.....its not a surge or a Yo Yo effect, its a Hiccup/jolt and then never does it again!

Hi Paul, Thanks for the help...I'm certain its not Yo Yo or surging. Its as simple as I have a jolt or Hiccup when i pull away in first gear from cold, just as I let out the clutch. I have given it more revs, less revs...I can't get around it. After that, it never does it again!

Thats may be the case for some regarding the ABS test but it only happens with me once when the car is started from cold. If i stop after the car is warmed up, then pull away again, I get nothing! So if it was an ABS test, I would have it everytime I start the car!

Paul · May 6th, 2003, 01:59 AM

The ABS test is a valid suggestion, however you dont really feel that, just hear it (quietly).

Paul, Its not only me that has this particular problem....Not surging of Yo Yo but this first gear from cold thing...here is the post

_____

my March 03 build MCS does this.....but only when the engine has just been started and the car pulls away for the first time. It doesnt do it any other time, only from first pull away. I am somewhat perplexed as to what it could be. I am tending to thing software calibration and emissions related?

Thoughts anyone?

Paul I have e-mailed him with my number so hopefully I will get to talk to him before I go and torch my dealership!!! The engineer I spoke to gave it all the "its a MINI thing" yeah, my a*@s

Nope, this is the problem, I know what happens when the DSC is on, its not DSC, Yo Yo, Surging, My Driving, but it doesn't matter now, i have found someone who i contacted in the UK who has the same prob. Hopefully his car is going in to thave the problem fixed and from that, I will be able to go to my dealer with the "Fix"

I know, it's been reported by several owners (as I said earlier). There must be more than one in the UK.

May 6th, 2003, 08:55 AM

definently not the ABS test, I can hear that and they do not happen at the same time. Does anyone else get the hiccup at 2,000 RPM when off the throttle?

-Andrew

Wesport · May 6th, 2003, 08:56 AM

Yes - I have it in Atlanta with my March build MCS. Exactly as you described. Skips a few beats around 2k rpm in first gear starting off from a stop. DSC on or off, hot or cold. Only in first, and mostly from a stop. Please let me know if a fix is found. I am about ready to start perf mods, and want to get this resolved first - or they will blame the mods and I will never get it fixed.
Thanks
Wes

May 7th, 2003, 02:51 AM

OK, it is not a clutch issue. Today I got the clutch totally engaged, and about 3 seconds later I got the hiccup. Must be software.

-Andrew

Wesport · May 7th, 2003, 05:47 AM

Yes - got to be software - don't know what the computer is killing though - fuel, spark, or air (throttle body). I wish someone would get one on a dyno and try to reproduce the problem with instrumentation on the motor.
