It's FREEZING and my R56 is sputtering
It’s been in the single digits here in the Northeast. I know our cars do not require warming up, but since I was already outside walking the dog, I started the engine and blasted the heat and went inside to get ready to go to work. 10 mins after starting the car, I hear the engine started to sputter. I rushed outside and the CEL was on, so I immediately turned off the engine. I started the engine back on and everything is back to normal- Cel disappeared and engine sounds great again
FYI- car has 57k with new spark plugs and new timing chain assembly replaced. I always use quality gas from Sunoco and Shell. Is this a sign that my HPFP is going bad or is it something else?

I don't think it's the hpfp. When mine went bad the car took a couple times of pushing the on/off start button until it could start running fine. I think i had to do that for the system to build up fuel pressure. Never had a cel light come on when my hpfp went bad.
Your car could be fine. Just a weird fluke that randomly happened. My 2 cents.

^ yep. Sounds like the intake manifold. I got my MCS in Nov 2008 and a few days after this happened. Talk about buyer's remorse! This same issue hasn't happened since the dealer replaced the manifold with a newly designed one under warranty.
HOWEVER, I I posted elsewhere: my car was surging on start up (single digits here in CT) and I smelled fuel. I took it to a mechanic and it's throwing a "throttle body" code.
*sigh* Somebody please talk me out of selling this car! I love driving it but have had so many issues in the 4 yrs I've owned it. Just when I think I've worked out all the quirks, a new one creeps up.

My wife's 2010 MCS had the same issue. Idle was revving up and down during a brief warm up. She went to take siff and the car had no power. CEL came on and then turned off after restart. Idled and ran fine on the way to the dealer later that day. I did scan 2 codes, P1638 and P1639. Replacing said part to eliminate this from happening again.

Actually, from my understanding if it is the intake icing problem it will not harm the car. It is just frustrating to start the car andhave it sputter. With mine, I would shut it off, wait a few minutes and restart it. With the warmer weather coming, the problem should go away until then next cold snap. So if the dealer doesn't cover it, it would something you could live with. Also, it needs to throw a cell before the dealer will cover it (at least that was the way it was when I had the problem).

I had my intake manifold replaced right after I got my car in Nov 2008 (it's a 2009 MCS).
I had another sputtering on start with surging and fuel smell. Turns out it was the P1638 code and the throttle valve was sticking. They found the coolant temp sensor was erratic on startup and replaced it. Fingers crossed that all is now well!

Resurrecting this from the dead one year later. This is my first winter with my '10 MCS, and yesterday afternoon (3 degrees F) was the first time she threw P1637 and P1638. Does anyone know if Mini switched to the new "Cold Weather" design intake manifold on production models? If so, do you know when they made this change? Is there any way to determine if my car is fitted with said manifold by looking at it?

Here is the link to the Cold Climate intake manifold for icing on the throttle and info.

That's all the info I have. Thanks
