We have an 06 MCSa and I noticed a couple of times when I gave it full throttle (in automatic mode) coming from a dead stop at a light that it would over-rev in 1st gear. When I looked down, I saw 7,000 - 7,200 RPM and let off the gas and then it would finally shift.

Anyone else every experience this?

Car is bone stock.

 

For the record, I'm in my mid-30s and I'm not imagining things.

 

hey penelope

what mode are you in when you get the 'over revving'?

 

If you floor the throttle you put it in kickdown mode so it will hold the gear you are in as long as possible. Just don't mash the gas to the floor past the detent and it will work fine - better yet use manual mode for best performance.

 

PS: Techincally speaking, the car is not over-revving (which is a bad thing that can destroy your engine), its just redlining it.

A little info I found quickly to define it: http://pages.sbcglobal.net/gorf/bmwt...ntoverrev.html

 

Right, the car is just using its entire powerband to get you were you want to go. You can smash it and hold it down till the car gets to the desired speed. It will cruise to redline through each gear it you keep the pedal to the metal

 

Since first gear is extremely short geared, it builds revs very quickly. Ours does the same but usually DSC kicks in dialing back a little of the thrust. Just had to find that out as soon as I hit the 1250 mile break-in!

 

There is an engine rev limiter that will kick in if the revs go too high. The Tach might also be off..

 

Actually, the car revved over and beyond the redline and it does not seem to be making any power up there. I forget exactly what RPM it hits, but it seems like 7200 or a bit above. I know there is supposed to be a rev limiter in the Manual MSC and in the case of the MSCa it seems to be around 6800 as one normally can not rev beyond that. When you try the car just shifts regardless of whether you are in manual or auto mode.

This happened 3 times in Auto mode and it happens regardless of DSC being on or off.

Wierd stuff...

 

I think what you are experiencing is that the engine revs faster then the ecu can plan for a shift of the tranny. I noticed this to be very evident when I had a lightened crank pulley.

 

I get the feeling no one else has experienced this in a MCSa...

 

i think the actual rev limit of an S is 7200 rpm...

 

No. 6800 RPM.

 

I tracked my MCSa at Putnam Park, IN, this month for a 2-day driving school with BMWCCA [Buckeye Chapter]. Since the car is new and just out of breakin, I wanted to see what it could do, as well as learn more about high performance dirving. I was in the manual mode when I floored the car and experienced the same over-revving as did Penelope. In fact, when I got back to the paddock my friends all asked WTF was wrong with my car. It was pretty strange as well as disconcerting [not just to me, but to my instructor as well], to say the least, and it happens when I am in the manual mode...pops in and out of supercharger in a herky-jerky manner, even though my pedal is floored. I decided that that was not going to work at all, so I ended up spending the rest of my track time in the "SD" mode, where the engine worked phenomenally with no hesitations at all.

 

When I put mine in Manual and smash it the car revs to approx 7000-7200 and shifts great through the gears. Maybe you need to visit a track so you don't worry about doing this. I've done this through past 4th gear without that much herky jerkiness.

The jerks seem to occur when you have let off the pedal at high rpms suddenly rather then gradually. Or when the car is attempting to shift.

 

I guess you and I are the only ones with an MCSa and equally heavy right foot.

My name is Alberto btw. The wife named the Mini Penelope but I enjoy driving it as well.

I can't say I experiened this in Manual mode. The operation seems pretty reliable in manual mode unless I floor it and downshift at which point you risk tripping the "downshift button" at the accelerator's full extension. I'm glad I'm not the only one though.

Regarding the herky-jerky operation, do you notice that when rolling on/off the throttle? I feel something as well, but I suspect its the passenger side motor mount. I see some crud below it in the engine bay and there have been reports of brokend passenger side motor mounts.

I'm going to try it in SD to see if it happens there as well.

 

Are you saying that your MCSa shifts at 7200 in ALL gears when you are on it? Mine shifts around 6800 regardless of whether I'm in D, SD or going manual through the gears.

For me, the over revving (or revving beyond the indicated redline) only happens in 1st gear when I'm getting on it full throttle from a stop.

 

Since I was on the track and was just coming out of the last curve to enter the straightaway, I was already in the 3rd gear of the MCSa. I floored it and the "bucking bronco" ride began. I couldn't believe it was happening, so I continued to drive the course and had it happen two more times around the track [on that long straightaway] before I finally decided that enough was enough and went to the "SD" mode.

 

I wonder if what you/we are experiencing has more to do with the Bypass valve. Just a wild guess.

 

Smash the pedal beyond the "kick down point" and watch the needle fly
Although this might not be good for your car

 

I find the automatic in the cooper nervous, jerky and slow... often times just confused... and may be scared to shift...

Just drove a cooper auto loaner for 100+ miles. No comments on the power difference as that is quite evident. however i am afraid to admit, this was probably the worst automatic car i have ever driven. tremendous shift lag when you needed to speed up and change lanes, horrible low speed manuvering around the city. The automatic feels as though its trying to figure out what gear to be in relative to the speed each and every time.

I briefly drove an MCSA for about 2 miles and found it responsive... almost too responsive as though it was constantly shifting gears. I didnt give it much thought at the time since I was busy playing with the paddles however after this loaner drive i am sad to report that the automatic in the mini cooper is just unacceptable in today's driving standards. Perhaps the functionality is masked or overcome by the power performance of the MCS but still may be the most jerkiest and least competient automatic to drive in a $20,000+ car.

EDIT: the MCSa was a better driver (not referring to power) around town overall. My wife and i went back and forth on automatic or Nav... Nav won in the end...

 

Everyone is allowed their opinion. I am not 100% happy with the performance around town but think it really kicks but when used in manual mode.

Although the more you drive it and the car adapts to your driving style the more it seems to work for the driver. Such as with me. The car doesn't seem to want to get into 6th when on the highway unless I sit at a constant speed for about a mile. I think this is due to my heavy right foot haha

 

I've noticed this also - my only complaint with the auto. I just upshift into 6th with the paddle instead of waiting.

 

Just checking, but you do know it is an entirely different transmission in both cars - the MC is the CVT (continuously variable) and the MCS is a 6 speed AISIN auto - so its not the MCS overcoming the tranny, it simply has a different one

 

Thanks for the comments. Thus far it seems like only myself and the welschman noticed the over-revving problem on the MCSa.
