I'd think that would be a dealer part, but check with some or sponsors here. They will be able to get you one & save you some money too.

Welcome to M/A

 

The high pressure fuel pump on the R56 S has been a problem for Mini. They have sent out letters to owners that the warranty on the high pressure fuel pump has been extended to 100,000 miles. You should check with a dealer unless your mileage is more than 100k.

 

Mini of Murray in Salt Lake City?
Go to MINIUSA.com locater.

 

I'm having sort of the same issues. But mine doesn't stall. Just no power until warm when its cold outside.

 

Anybody??

 

It's possible you didn't get to the stalling stage yet.

 

:cornut: Now that's how to really encourage new comers to ask questions and show them that we are a friendly site. This is exactly how the SEWING SITE started going down; by giving WISEACRE answers to legitimate questions. turboguy327- I'm bumping your answer until a friendly gear head comes along. We can engage in badinage with long time MA'ers that we know well. I laugh at all of this directed at me because I'm very familiar with you guys and know that you mean well and are trying to provoke laughter but, newcomers don't know that. I apologize for causing any ill feelings here but, we have a fantastic site in MA and we should keep it that way.

BUMP! BUMP! BUMP!

I'm having intermittent problems with stalling at startup. My 2007 MCS has shown a reluctance to stay running until the third or fourth attempt, and then sometimes I'll have to put my foot in the accelerator just a bit to keep it going. I'm glad to read here that the warranty on the fuel pump has been extended. That's not a job I want to pay for nor do I feel comfortable doing myself.

 

Having the startup issue all the time. Have to get it going with foot coaxing the gas pedal and hold at 3000 rpm for 20 secs. Some backfires, smell, and a little smoke.
After that, it runs fine.
If it sits for 3-4 hours and i have to go through the whole exercise again.
Into the dealer next week - folks at my local independent shop suspect the HPFP, but say they would rather Mini replace it at the dealer since it's all warrantied for 10 years / 120k miles.

 

Is your check engine light on. If so get the codes read and see what direction takes you. But I'd lean towards the hpfp. Or possibly carbon buildup on the intake valves

Keep us posted

And just so we are all clear. The hpfp is an easy job. Anyone with basic hand tools could install one within 30 minutes

 

I know i have bad carbon buildup on the valves - my local place told me they could pull it apart, and soak the area to remove the worst of it (although they couldn't say how much of the hard build up would be removed). I declined, preferring to take it straight to Mini, and get the whole walnut blast thing done. More expensive, but should completely deal with the situation and take me back to bare metal again. Going to Mini on Tuesday. Will update when i know more. (does anyone know what the walnut process typically costs?)

 

You could also do a Sea Foam treatment yourself very easily. It does work.

 

Other's have posted it as being around $600.00, but I'm sure this price varies by dealer....

 

***UPDATE***
Had a bunch of work done at the dealer - Walnut blast on the intakes ($500), replaced the auxiliary water pump (recall item), replaced drive belt (which was wearing out and due for replacement anyway), and REPLACED THE HIGH PRESSURE FUEL PUMP. This sorted out the whole starting issue immediately. There is a 120k / 10 year warranty on this part, so the cost for this was all covered by Mini / BMW - yay. It also required about 4 to 5 hours of the reprogramming / updated to get the software back up to date.

Either way, it finally got sorted out after many months of traumatic starts in the morning. Now i can smile every time I punch that button first thing in the morning.

One extra comment - the intakes were described as "extremely nasty" (75,000 miles on the car) , but i got a picture "before" and "after" - a HUGE difference - I will post these when i get a moment.

 

Another UPDATE:

I finally took my mini to the dealership because not only was the starting getting worse, but I could sometimes feel hesitation during freeway driving. I mentioned that I thought it might be the HPFP due to forum threads and youtube videos. The service adviser told me he hated those sources of information because they are so frequently wrong. I can certainly understand and sympathize, but in this case he apologized when they did find the HPFP was failing. It's being replaced now at no cost and I should have the car back tomorrow.
My mini has just over 66k miles and except for the rough running from the carbon build-up and the HPFP, the car has performed great.

 

Thanks for all the replies. My 2007 CooperS is doing the same thing, and like the OP, only on cold mornings. I'm glad to hear that I'll probably get a free fix on it, too.
