My 2008 Clubman S with 104,000 miles had recently started missing on startup after sitting all night. It dies 2 or 3 times then idles rough but will start running fine after 30 seconds or so. No more problems with starting all day, no matter how many times it's started and it seems to run fine. It's just first thing in the morning after sitting in garage all night. The check engine symbol came on during operation a day or 2 after problem started. Had it checked by a mechanic and had a midfire cylinder 2 and 3 code. I've had this before and had plugs changed and 2 coils replaced. Had emmissions tested for license plate renewal in September and passed just fine. I know there have been carbon build up problems with this engine and I ran seafoam through the intake during the summer. Not much smoke at all. I have seen mention in other threads here about a HPFP. Any suggestions?
Seafoam is not going to clean carbon out of your engine. The only thing that will do that is walnut blasting. At the mileage you have I'd say carbon is a pretty safe bet. There is an extended warranty on the HPFP. You might want to check with your dealer.
Made an appointment with MINI of Nashville. They changed the HPFP at no charge and it took care of the issue. They also said I had other things to be concerned with. 1. Vacuum pump and hoses. Cost $1.020.00. The said it could damage turbo if not replaced. 2. Water pump starting to leak. Cost $810.00 3. Passenger side axle seal. Cost $1,780.00 most of which is labor (12.6 hrs) because they said they had to remove transmission. I took it to a import repair shop which was recommended to me by a friend with a BMW. He replaced the vacuum pump and hoses, which he bought from dealer, for $661.00. I also asked him to look at the other 2 items and see what he thought. He said water pump does need replacing and he'll do it for $410.00. Doing that next week. He said we just need to keep an eye on axle seal, could have been something just leaked on to it. I guess I'm satisfied. Any comments or advice? Thanks
Axle seals on those are pretty common....But you dont have to remove the trans...Maybe for the rear main seal ....??..
Bitsy Mae doesn't have an issue starting in the cold, however, she does sound a bit rough/more ticky than normal. I'm bringing her to the dealership saturday and I'll ax them to check it out. I'm hoping that since these engines are rather loud running normally that shes ok and just as pissed about being out in the cold as I am.
