Starts fine and runs for about 5 seconds, then gets a really lumpy idle for a few seconds and then is fine. My 05 MCS has had no updates. When I got the car it was fine and then about 6 months ago started doing this. Cannot be from software update, since I haven't had any.

 

Has any one used the lemon law concerning this problem? I'm not saying I want to get rid of my car however I just want to explore all the options I have. It is very dishearting when you buy a brand new car and it won't start in the morning.

 

My mini and my boyfriend's mini have the same problem.
But it hasn't happened lately.
I think it happens when its been sitting for a while and its been cold.

 

yes, i have, i had to get rid of my '02 for this reason. if you meet the conditions, however, it is not likely that you will actually need to go all the way through to arbitration, bmw will settle with you prior to that. you will need to evaluate the options/risks for your individual case, and realize that you may need to accept that you will have to pay a per-mile "usage" depreciation for the time you have had the car. i can send you a private message if you would like... ?

 

If we could talk that would be wonderful, I am new to this forum so I am not sure how to do that.

 

It would start up after sitting a day or so, then stall....then start again and keep running as normal. It was like it was burning all the gas supplied to it and then running out...I found as another poster said to let the fuel pump run a few seconds longer...problem gone! BTW: Only use Chevron 91 octane and always will in exotics! If an emergency...will put some Shell in but that happened only once....so far. I am a believer that the ECU "learns about fuel types/additives. ALL GAS comes in thru the same pipeline in reno..then the tanker gets a shot of the brand's additive! (I think Arco stuffgets a shot of H20 instead!) Even my Honda Vtech (Runs on almost anything) stutters a little on Arco...garbage IMHO!

Yes...the Gas we get on the west coast is POOR! Should get worse when they add the Ethenol back in OCT (at least that is what the pumps say...could be in there now)! Good news is that it should run better once this blasted heat is over and the air is a little more dense!

 

of course, no problem- i will send you a private message...

 

I've had this problem too! Wow. Atleast I'm not alone.

I'm going to try some Chevron branded Techron Fuel system cleaner.

I'll let u know.

 

I havn't had this problem yet, 04 MCS (09/03 build). I have had to hold the starter a little longer... I probably just need a new battery though. The battery will be 3 years old in November (delivery date).

 

I have the same problem. When I took my car in for 10,000 service, I mentioned it to my service advisor. They checked it & said that they couldn't find any problems. I'm still having the same problem where the car stalls upon starting. Of course, this only happens when the car is parked for more than a day or so.

well i had the problem where i would have to hold the start in for a little before the engine would turn. i noticed this very first event in the winter, i just chalked it up as a cold engine, but it slowly seemed to recur. I figured it was maybe just something that would go away. but this past few weeks it rapidly got worse and now i can't even start my car. i have an '02 S. if anyonw in the area can please help me. this car is kind of like my primary mode of transportation, and quite frankly i'm to afraid to drive my dad's explorer anywhere....it's WAY to big for me. please help!!

 

I just had my 05 MCS re-flashed with the latest software... No more stumble on cold starts...

 

mine has done it since the day she came from englang

 

Update. If I turn on the ignition, but do not turn to start, and leave it there for a couple of seconds... you can hear the fuel pump prime... no more stumble... I used to do this in my prelude too, helped when i was low in the tank.

 

Randy Webb suggested that I get the ECU flashed by the dealer to fix the stall problem. I brought my 2003 MCS into the dealer last week. $75 later the problem is gone. It has started on the first try ever since.

 

It's me again...So I had to drive my boyfriend's mini this morning and it started having this problem but it had been sitting overnight I drove it last night!! and its obviously not cold!!

 

... iits not related, but, good idea is to never let your tank go below 1/2 full, helps to avoid rusting of the inner tank surface...

 

Same experience here as others have stated. After sitting long enough to cool off, my '05 MCS starts fine then stumbles for about 3-5 seconds, then smooths out and all's well. I just never think of it when I'm at the dealer for service. So just re-flashing the ECU will fix it?

 

I have a 2003 Mini and I just noticed that when I start it it stalls and then the 2nd time it stays running,only had the car 3 weeks so I didnt know it happened to alot of Mini's

 

so i was going to get an 06 mini, but does the 06 stall as well?

 

Had the problem with my '02 MC and started having issues with '05 MCSa. Got tired of hearing that they are working on a fix. No s/ware update fixed the problem for me..... This was just one of many problems with the '02 and one of a couple of issues with the '05 that just got too old

Second Mini is gone and my '07 Mazda CX-7 has no issues (knock on wood). it is a shame that Mini can't get it all together (IMHO)...

Good luck with your choices!

 

Question... what's the spec for residual fuel pressure in these cars? Still waiting for a current copy of the TIS to arrive...

 

Just brought mine to the dealer for the 10k oil change and mentioned it. Lets see what the latest dealer reply is when I pick it up.

Mine even stalls at stop signs sometimes!

 

Hey guys!! Seen your post on this problem. We here at the dealership have been using the newest software and seems to have helped a bit. But until companies start using better gas quality during the summer time the problem will go on.

 

I have been having this problem off and on with my 03 since the day i got it almost three years ago, yesterday though it got so bad the EML & DSC light kept coming on, i had to keep "rebooting" the car to be able to drive. I left it at the dealer, yesterday because its undriveable!! Maybe in this case its more than just the software. I've also had at least three throttle body replacements. I'll post what they do to my car when i get it back...
