no need to make a video.....i know what you mean with the morning stumble but thats the only thing i found for bulletins

 

I took my car in for an ECU update this Monday and i still have the rough idle in the first 45 seconds of cold start with the threat of stalling.

So it doesn't seem like the newest ECU is the answer. I plan to call my Service Advisor to tell him the update did no good. But i'll print out and show him your post about the valve and see if it helps.

Thanx

 

I've got the same stumble and had my SC valve replaced within the first 1300 miles of ownership. :-(

 

I had the same thing done and the problem came back. Talked to the dealer and he stated MINI knows of the problem and is working on the fix. He put me on the watch list for when the fix is released. BTW--Mine problem is sporadic and only happens in the afternoon after work, usually when its really hot outside.

 

They have been saying that for 6+ months.

 

I got a cold start everyday..on my new 05MCS...I have felt a very weak star at traffic lights to a point where my car stalled today when the light got green... I thought it was me at first getting use to the new clutch/throttle but I swear..is the car.. HAs anybody felt any of this symptoms outide on the road??

 

That also may have something to do with the horrible throttle response It seems to be a problem with the drive by wire cars.

 

Unless I'm mistaken, the original topic of this thread (and most of the posts) has to do with the car stalling when it's first started in the AM, even before the car is moved. It just starts, develops a very rough idle and stalls, even if there is no attempt to place the car in gear and release the clutch. My car has a mild cold start issue, but others have it much worse.

As for the problem you're discussing, and many of the throttle response comments I've heard, all I can say is my car does not exhibit this behavior. Are you sure you didn't just release the clutch with too few revs? Try again at about 1500. At 1100-1200 it does sort of bog down, but at higher revs, mine springs loff the line just fine. At least when I remember to disable the DSC that is.

 

I highly doubt all these people r poppin there clutch....you can tell if you did that......I dont know about anyone else, but im able to release the clutch slow with no throttle.....i dont do that as a normal habit but wanted to see if the car is able to control rpm .....

 

Yep, I've done the same thing for the same reason. You can, in fact, release the clutch slowly from idle and the car will pull away slowly. However, once underway, it will pull away slowly until you get some revs no matter if you floor it. And, if you don't have many revs you must release the clutch slowly to avoid stalling the car. This is true of all manual transmission cars. The question is whether some MINI's have a problem that exagerates this situation. Clearly there are more than a few people who think there is a problem. So far, knock on wood, my MINI is not afflicted.

Thinking about it, it comes as no surprise to anyone that a 1.6L engine makes no power down low. And the fact that our cars are supercharged doesn't help a bit until the revs come up. In reality, the slightly lower base compression ratio probably hurts it as compared to a naturally aspirated engine. You gotta keep the revs up.

 

I just purchased a 2003 MC and today was my 2nd day driving it in the 24 hours since I purchased it. Now, I have driven many, many other manuals before so I know it is not my shifting that is causing it to stall on me. She starts up just fine. I engage 1st gear and as I lift off the clutch she wants to stall and usually does so. Today I experimented with her and tried disengaging the clutch at various speeds from wicked slow to fast. I also tried adjusting the amount of throttle I gave her as well as bringing up the RPM's and dropping it at various times. None of these things helped. At times, instead of stalling, she would just bog down and buck in first gear. Giving her gas didn't smoothe her out and in fact, the RPM's didn't change either. Lastly, this is happening when the engine is both hot and cold.
Some questions:
Has anyone tried putting a resistor on the thermostat to see if it makes a difference?
When she stalls out on me, I have to turn the key off in order to restart her. Is this normal? (If the radio is on, I can't even tell if she started or not)

 

The throttle is a little different since its a by wire system, so you have to really be sensitive with both feet balancing the catch point. If you come off the clutch with less than 2k rpms, it tends to bog a little if you're not very smooth. This is one slightly frustrating thing, but the challenge is worth it. Any revs over 2k rpm tend not to need such dainty clutch action and can spin the wheels.... My '04 Cooper appreciates the love. And is a much better shifter than my girlfriend's Civic- she even admitted this to me last time I let her drive the Cooper.

If you're patient with the throttle who has a mind sometimes distant from the engine, you'll master it.
Plus, I have this engine stall problem with a very long start time. If it sits for more than a day or two (sad I know) it sometimes needs two tries to start. I think the summer gas is a weak excuse as well and it was exacerbated by the emissions update. Hopefully a fix will come soon.

I would have to say I have a hot start since it has been running 100 degrees or more for days now where I live and my car sits out in an open lot in the sun. I start my car in the parking lot where I work, turn on to a street and come to a stop at a stop light in a block, and my car will suddenly not move. The engine is still going but no-go. The service engine light and the EML light come on. I can turn the engine off and start again and the car runs but this is after I am honked at incessantly because I am stitting there. The service engine light stays on for several days but the EML goes off. I have an appointment at my dealer to hopefully get this fixed. I have about 4,000 miles on a 2005Sa.

 

I was at my dealer today (MINI of Towson) b/c of the SES/EML lights coming on last night. My tech explained to me that installing widebore throttle bodies in 2005 models will not work most of the time as many of the tuners out there are using pre-2005 model cores and boring those out instead of using new 2005 TBs. Apparently BMW/MINI changed some of the electrical wiring with the new TBs. Anyone heard about this? I got an M7 TB and the EML light came on almost instantly. Peter has been awesome, but I think I'm just going to stick with my stock TB if I'm going to have this problem in the future. Thoughts?

 

I couldnt tell you what everyone else is doing but our Dinan Tb are good for 02-05 cars......We do have a core charge on em and the years shouldnt matter from what im seeing.

Even the OEM is good from 02-05

 

Sounds like Ski's tech has... umm.. different info. Good bet he's mistaken.

 

My 03 S has done it for over a year now. I have been promised over and over that "this update should fix the problem" yeah right
I got my car back last week from 26k service. Latest software installed...
Car stalled this morning

 

Did you see my post 1 page back on the bulletin for stalling?

 

Well, if the ECU is determining the air/fuel mixture with considerations to engine temp, rpm and other assorted variables, a resistor on the Tstat might help prevent the stumble/stall. (more complicated than that, but you get the idea?)

 

I did not read the entire thread. What I read was that people should note on this thread if they have the stalling problem.

 

I got my new 05 MCS at the end of May. It ran perfectly for about two months (on SHELL premium). Then it began to have difficulty starting smoothly in the morning, or after having sat for several hours (even in warm weather). Seasnal gas reformulation does not explain why it ran so well for two months, but how could the ECU have gotten a bad attitude? It seems to be a mystery to everyone, but you would think the pros could get to the bottom of it.

 

another stall. 05 mcs, two months old - won't hold my breath for a fix.

 

I have 800 miles on my '05 MCS, and I have been having this problem since 200 of those 800 miles! Hopefully your list will initiate action on the part of MINIUSA. Thanks for taking the initiative!

 

My fiance has this problem with her Mini S (2004) with 37K miles. Its done it since the time she has had it with numerous ECU updates and no resolve.

I decided to upgrade her spark plugs to set of Denzo Iridium's and it seemed to help out the problem a good amount. Only the occasional stall now. But its definetly better.
