2010 20K miles Mini cooper S
I purchased it second hand and everything seemed fine. Bring it to the dealer for service and recalls. They did a Timing chain update, Aux Water pump, talked me in to alignment and cleaning the injectors. I then drove it straight to Honda where I purchased it to have it de-smoked from the previous owner. They must have had the car idling for hours I imagine to keep the AC running as they cleaned the system. (I noticed average mileage went from 25mpg to 18 mpg just for that one tank)
I called and they said the engine would "reprogram to my driving"

When you come to a fairly quick stop the RPM drop below idle and then kick back up and it settles. It can be a little strange when driving long trips with stop and go traffic. You can hear this from the motor as well as see it on the tach maybe 300 RPM but it kind of lunges like something is catching up. I have never seen it happen when very cold, takes 5~10 minutes. Never seen it happen when in Sport mode either.
It is almost like the Automatic transmission doesn't release the clutch quick enough. Dealer of course kept the car for 1 week and found no errors or issues at all. I even let the service manager (supposedly) take it home so he could drive 40 miles. I also find the gas pedal very touchy in the first inch of travel which I accept could be normal as they say. They loaned me an identical 2012 for the week and it never had either of these issues and was a joy to drive. Made me feel like I shouldn't have purchased used or I need a different stealership? Anyone had issues like this? Any suggestions? I've already wasted a ton of $ in time seeing them. Is it worth a try to disconnect the battery overnight? Maybe Honda idling the car for hours messed with the computer? Another independent said that cleaning the injectors at 20K miles is unheard of even if it is 2 years old. They said "we will check it and only clean them if we need to" (That service was $500)

 

Just for reference I took a little video.
This doesn't seem normal to me and is felt as a lunge which doesn't really show up on the video due to stabilization of the video. Check the Dip in RPM and recovery on the tach when coming to a stop. It doesn't happen when cold or in Sport mode.

 

I've got the same issue

 

That's not what I wanted to hear!
You tuners, is there no fix for this?

 

I get the opposite effect on a 2009 manual transmission. My rpms increase slightly when braking only to settle back down to idle on full stop.

 

Can Anyone tell me if this is "normal" for a 2010? I took it to the dealership again and at first they called it a 2-1 downshift issue. Now they are saying it is normal for this year. Very frustrating since the 2012 loaner they gave me is great.

 

Update is that all the 2010's I have driven do this. The 2012 does not.
After a 3rd trip to the dealership they checked and it seems I'm not the only complaint. If enough complain to Mini they will write a new map to fix it.
Weird you should have to go through that.

 

Disconnect and reconnect the MAF Sensor a couple of times to clean the pins/connector. I had the same problem and it went away after reseating that connector. Do it with the engine off of course!

 

Thanks for the tip, I'll try that but can you point me to where that is?
Thanks

 

I had that same issue in my 2008 after the dealer updated my ecu. I don't have that issue anymore after my tuner "RMW" fixed it.

 

My Clubman S doesn't do that, it's idle is very steady.

The accelerator is very touchy in the first part of travel on mine also, it is less noticeable in sport mode.

Mine's not an S, but after threatening to stall several times at an intersection 2 minutes from my work, she finally did stall, but started up fine and continued with no issues. No issues last 2 days. Seeing Mini on Monday...Have a 2010 Clubman

 

Should be on your air intake hose just before going into the air cleaner.
Oblong plug.

 

See attached picture, red arrow... Just disconnect it and reconnect it a couple of times. It has a small lock on it, I think you press it to release the connector.

 

Had the same problem....the dealer adjusted the idle by 100 rpms...only happened when the car was warm... This was after they updated my ecu

 

OK Got excited thought it worked but as soon as it warmed up the same problem. Even tried a little electrical cleaner De-Oxit which is great stuff. I wrote a letter explaining everything to Mini as instructed by the dealership. I get a response "We are sorry you are having problems with your navigation" Cause I mentioned a new engine map but described all the problem, its like they didn't read the 1 paragraph email I basically educated the dealership on the issue and now they also notice it on the 2010s. Mini does apprently have recorfds of other complaining about it but probably wont fix it unless they get enough complaints.

I was wondering if the custom maps would fix it.
Anyone know anything about the ALTA performance? Probably talked about here somewhere.

 

Sorry it didn't work for you...

 

Here is what really is unnerving. The Service manager at my dealership says they (Mini) have heard of the compliant before and might start working on an ECU map to fix it. He suggests I send a letter to Mini to help prompt a solution. Customer service says that there is no place for me to send such an email or letter and that my only path is through a dealership. Talk about passing the buck ! Urrrrrgh
