Misfires still a problem: Dealer said carbon buildup.
Hello everyone,
I have a 2007 MCS. That's been having misfires for quite some time now. It's been in and out of the dealer and shops ever since I've had it. Recently it began to have misfires, so I took it to a shop (that obviously didnt know much about MINI's as they wanted 2000 dollars to perform a carbon cleaning) Besides that they did run a compression test and said one cylinder showed signs of low compression.
Some background. It had this same problem before. Changed the sparkplugs and ran fine for 3 months. It has gone through 3 sets of plugs in 1 year. On top of that. 2 out of the 8 plugs came out with chipped (electrodes) I think that's what that little part of a spark plug is called.
Anyway I finally succumbed to what the dealer had been recommending and went ahead and had the valves cleaned. It then ran OK at best, for a week. Now it is currently having the exact same issue as before. I feel really frustrated that MINI charges 950 dollars for a carbon cleaning that was supposed to fix this issue. Clearly it did not.
Anyone have this sort of problem? Really need a solution to this. Trying as hard as I can to keep this MINI, trading it in would be heartbreaking, but if this problem is not fixed soon I might just have to give up my MINI wings and move to a soulless Ford. Please help me out. If you have had this sort of issue I'd appreciate you sharing your experience.

Hello friends,
First off I want to thank you all for your replies and suggestions. Secondly I am new to this forum so I don't know if you all will get a notification for this. Sorry I don't know how to tag other users yet if that is necessary.
Now onto what I found, after the long headache and watching videos and hours looking for anything that might help me on this forum, I decided to go out and take a look under the hood and see if I couldn't wiggle some do-dads to find out what was causing the problem. Luckily I found out that one of the ---Coil Packs--- was indead not working. I tested this by first scanning the car, first scan had a misfire on cylinder 1. Pulled the coil out and swapped it with another and just like that the misfire moved to cylinder 2 (I know because I was disconnecting the coils... while the engine was running) while that may be a no no, being the daredevil that I am, I did it anyway.
Reply to some suggestions,
To, JCdubGerm as I said it has been in and out of shops since I've had it, but I failed to mention that it has gone to the dealer for all repairs before I got fed up with bringing it home from 81 miles away just for the problem to come back in a matter of weeks. But, yes it is taking the journey tomorrow directly to my nearest MINI dealer and all problems should hopefully be resolved as I know what the problem is (I hope). Thank you for your suggestion!
To, Mininotcheap I have to say I agree with your username. So what you are saying is that MINI will cover my HPFP if it goes bad as well? (Car is under 10 years old and just above 75k miles.) I hope they change mine if it is bad as well. Happy your problem is resolved. Keep Motoring!
To, Zillon yes they charge 950 dollars plus tax. Although that is what they charge I did not want to pay that much. Went to a BMW specialist and got slightly less ripped off at 648 :,). It's going in for repairs at my nearest MINI dealer tomorrow. I will ask them to scope the cylinders as well, thank you for that suggestion I had not thought about asking them to check that.
To, nkfry I think you are right on the coil pack there (I did some "top of the line" testing myself). I doubt it's the timing chain though as it was changed around 7k miles ago. Thank you for the suggestion, if I had not found it before reading your comment I would've owed that find to you! Thanks for your suggestion!
