I have a problem with my 2007 mini cooper s. on a cold start it has trouble starting, and sometimes when driving it shortly after I put my foot down and it kinda lags slowly then like misfires and then the power comes in

Symptom when I first start the car is that it starts tries to hold cold idle revs and fails then stalls. can do it 4-6 times then will eventually idle but lumpily or with a hint of a misfire.

I believe this may be a common thing, but I am new to mini and this forum, any help would be greatly appreciated

Thanks

Nikki

May not be the correct diagnosis but it sounds very familiar

Check out the high pressure fuel pump fault. Its common, I have had it on 2 of my previous S models my current JCW.

Ho much does it cost roughly if it is the HPFP?

Thanks

Hi, the most costly thing was the part, I negotiated £220 from the main dealer for my JCW but I am confident you can get it cheaper if you shop around.
I have always been the type to go to my dealer for anything though and don't mind paying the premium as I have a long history with them and I don't trust any other garage through experience.

My first and second were done under warranty, third one, parts and labour, £340 I think from memory, and it was done last summer.

Let us know how you get on :)

Thanks for the help guys, this may sound silly, but how do you get a good will from mini? I bought the car privately, will this affect anything or should I be able to because its Mini and a known fault. How do you go about getting a good will?

Thanks

I am going through this exact problem. Mines a no start. So far the majority seem to think carbon buildup or fuel pump. Its being towed to the dealer this friday.

And MINI extended the warranty for the fuel pump to 120K miles or 10 years I hear....but only up to 2009 models. Mine is a 2010. Apparently the issue with their HPFPs wasn't fixed, I keep hearing this as a common problem.

I am not an expert but can only relay my experience in owning the first Mini Cooper S (super charged) in Canada, then a Clubman S (super charged) and a 2010 Clubman S (turbo). The first one was great without issues but the Clubman S triggered problems as described. After mind-numbing thought, I concluded that after relocating outside of the city (Toronto) to a place having more inclemment weather, that whenever I drove it in cold, rainy conditions and parked it in sub-zero temperatures overnight, the super charger would freeze up resulting in hard starts and limp mode in the morning . Only once the super charger was warmed up in the garage or once it became warmer during the day, did it act properly. I thought that by placing a furnace filter material on the inside of the bonnet/hood scoop would diminish the water coming in but sold the car prior to doing this. I did Google a fix for this but cannot recall what the remedy was. Hope this helps others. Old post I know. That said, I dont have the same problem with the turbo.

I have a 2012 R56 Cooper S with a similar intermittent issue. We've replaced that HPFP within the past year when the car would go into limp mode when accelerating. I'm also running fairly new plugs/coils and thermostat (Replaced the Jarvik Heart looking assembly). The car has 160K miles on it and generally runs great.

My wife and I have sorta isolated the hard start to a pattern. If we drive the car a 'very' short distance (say pulling the car out of the garage) or moving to the side of the house it is quite likely that the next morning start will take several tries and we will have to flutter the throttle to keep it running until it catches. It's not so tied to temperature but we rarely see below freezing in the pacific northwest. Add to that that the car generally sleeps in an attached garage that rarely goes below 40 degrees.

I don't buy the HPFP recommendation that folks and the dealer offer because we have experienced the issue before and after an HPFP replacement that was causing a limp-mode when accelerating.

It happened again yesterday, same scenario, very short drive Sunday followed by a hard start Monday. In fact she just started it fine now after the hard start Monday.. After the hard start Monday I let it idle for about 5 minutes before I shut it off. Two days ago, Sunday, I moved it to the side of the house (maybe a 30 foot drive) so my in-laws could park in our driveway, Monday it took 10 button presses and throttle wiggling before it would fire up.. Once running it runs great.. This is probably or 15th occurance of the sequence in 2-3 years of paying attention

It used to happen fairly often but it's rare now, my wife will not start it (her daily driver) without driving it or letting it idle for a while. With Covid we typically have the car sitting in the garage for days/weeks without use then it fires up reliably

At this point we think the workaround may be don't run the car for less than 2-3 minutes and I'll continue to monitor hard starts to see if my correlation holds. I'm pretty handy and do most of my own automotive work across several vehicles but I'm not a mechanic.. This issue has been nagging us for 3 or so years and I have no idea what the root cause would be. It's hard for us to replicate which makes it hard to attach test equipment.

If you have intermittent hard starts, did you have a 'very' short drive yesterday? That's what we look for.
