Stumble when accelerating?
#76
Having dealt with this issue since March of 2011 when we took delivery of our car, I am happy to report that "SI MI2 02 11" finally provided with our local dealership with the reference required for them to get the correct software update installed in our Countryman S All4. The engine and transmission behave so much better now. It's like driving a different car. It drives so much smoother. There's no hint of hesitation or stumble anymore. No jerkiness as you come off the throttle to decelerate. As an added bonus, it seems that gas mileage has improved as well by about 10%. Amazing! I knew that this would eventually come down to a programming issue, but I didn't have the patience or time to be a guinea pig. I thank all of you who were patient enough to be that guinea pig for me. I am a much happier Mini owner.
Cheers,

So I've complained on here a few times about the stumbling and I finally got to the dealer. They came out and told me it would be 30 mins and I'd be out. 45 mins later he comes out and says its telling them the reprogramming will take 3-4 hours. Its downloading slow from Mini. He offers me a loaner car and said they will bring me my car when its done later tonight (I live 50 mins away). They also replaced all the chrome trim pieces. Most had failed.
So barring any issues with the download/ reprogramming I should be back on the happy customer list...

Stumpling issues
I am also having stumbling issues on my Countryman which I less then 3 months old. I have also had the thermostat fail and a left indicator bulb fail. I amslo have a buzzing noise and a clicking noise coming from the engine. I also have a problem when going round a corner - it is like the car wants to go sideways.
My new car sounds like a diesel tank and to be honest I am sick of these faults on a car so young. It goes in for service tomorrow for these faults and I think I will ask them to check the fuel pump, flash the ECU and re set the transmission computer. But the sumpbling they say there is nothing wrong with the car - yet it snaps back and stutters when I really need the power.

The Mini Service department performed the version check after I gave them the reference number "SI MI2 02 11", and told me that the update applied to my vehicle.
As far as the slow re-programming time, I've heard that this is due to the face that after a programming update the computer in the car goes out to each device on the car's internal network and performs various checks and adjustments to those devices. Still, I can re-install Windows OS on my laptop in less then 3 hours, so I'm not sure why this procedure takes so long. The size of the wiring harness must have something to do with it. Maybe the devices are chatty and just want to sit and talk about the weather before getting down to business. Who knows...

So i brought in my car to get this issue checked out but they were unable to reproduce it. The service person stated that without it throwing a code that Mini service would not pay to check for system upgrades or anything. He says it is recorded and a paper trail is there so if it happens again let him know.
My qiestoion would be for those that have suffered from this issue.
1. Did you CM give you a warning or throw anyt codes?
2. I did notitce that in the description some of you posted the DM error. Did thid error show up orwas it only apparent when the Service scanned it?
Just trying to figure this out without having to got to the dealer too many times.

Did you mention the Bulletin SI M12 02 11 ? It relates to that exact issue. My SA didn't know about it either until I asked him to look for it. No codes or visual warnings given by my countryman other than me dealing with hesitation/stumbling and only at certain times…worse when colder out and no extra popping afterwards. Since my vehicle was in for other services…they performed the updates… It's been running better than ever! Speaking of popping…I have very little or none since the update…to bad I enjoyed it.
VIP exhaust soon to be ordered…better sounds on the way!

Check it out. A Motortrend Magazine journalist reports experiencing the stumble.

Having received the software update on our 2011 four months ago, I can tell you that, though the issue happens infrequently, the stumble still occurs every once in a while. It is not as violent when it occurs though.

Our CMSA4 had the violent stumbling.
They performed an update about a month ago and then a week and a half ago it did it again although less violent more stalling like, while my wife was driving us into the city. It was the last straw for me.
In addition to the thermostat problem many have complained of, ours has now been replaced twice with the same part#, not sure if it is the same part.
I have filed for relief under the Lemon Law in my state.
They've had the car for another 5 days now bringing the total to 20 days in the shop.
Corporate contacted my dealer who have been okay in this process and seem to realize the frustation this has caused. They are now trying to upgrade us into a new vehicle. I'm not sure how this will play out? Not even sure if I want the same car anymore cause of my concerns with our new baby and the reliability issues and stumbling problems.
I haven't mentioned the elephant in the room but have any of you seen anywhere near 26 miles per gallon? We traveled cross country thru Ohio, pretty flat and stayed around 71mph cause of the State troopers. Best MPG for the entire trip was 25.1 all highway. My average is 24.6 almost ever time I check, and I do my own numbers cause I don't trust the computer.
I think they've duped us all on the fuel economy of this car. Unless you guys can attest otherwise I'm really doubting any efficiency regardless of how or where this car is driven.
I'll keep you all up to date as this progresses but I'm somewhat relieved that I'm not alone. Maybe it's why they want to "switch" out our car? I wonder what they would do with the old one?

The average speed of the EPA highway mileage test is 55 mph. You can see fuel economy data for at least 25 CM's here:
http://www.fuelly.com/car/mini/countryman

The point of the tests is not to predict your mileage, but to allow you to compare among vehicle models using a single standard.

The same old story
They changed the TANK VENTILATION VALVE and it resolved the problem of irregular minimum. But the car continue to jerk in acceleration...
The last time they blamed the fuel poor quality. They suggested me the use of an additive for gazoline. I used this but without results. I'm waiting for a new recovery....
