    Mine sputtered a bit as well, but worked through it. I think the ECU gets all confused about what is in there. I put it in the gas tank once and will NEVER do that again.

    Yea, i read several threads about people doing that so I didn't do that. I've used seafoam for years on higher mileage vehicles and hadn't heard of using it earlier until we got the MINI and then I waited till it had 40,000 miles to use it. :Thumbsup:

    Last time I Seafoamed I think I revved it while it was still sputtering and it threw a CEL for about 200 miles afterwards. I just did it again last weekend and it went well. Then I got gas the next morning and bam... CEL. Not sure if it's related or not. Hope it is.

    So far so good. Did you try to clear the code?

    How much did you put in? I put in about a 1/3 of a can and no problems and it seemed to clean out the injectors nicely

    Had Advance Auto pull codes and it was Misfire on 3 of the 4 cylinders. Im sure it would have went out soon, but I had them clear them. No more CEL.

    Kind of a pain always getting a light, so I just wont Seafoam again for a while....or maybe just use less than a 1/2 can

    How new/old are you plugs? I think the amount is ok, I used almost the entire can as I couldn't get it to stall out with just 1/3. My plugs have about 10,000 on them. It didn't start after 5 minutes so I let it sit longer and it fired right up.

    Replaced them about 2 weeks ago, so theyre good to go. Even ran a lot better afterwards (plugs) . Same gap and all

    It definately had a good stutter going after the foamage. I think it was just after I did it I drove home from work (where i had foamed it) and then it sat all night and then I got gas 1/10 mile away and restarted. Probably still had some residue in it which tripped the knock sensor or whatever.

    Yea, should be good to go then. I haven't taken a long ride yet since the initial run but it's starting right up and idle fine.

    About the same, but mine acted real funny and the mpg went south until I could put in new gas. I believe the manual says NOT to use any gas treatment, but it was too late then.

    I use Chevron Techron in my tank & have never had any issues. Although I do not have a R56 so maybe that is the difference.

    I know there are some different usage instructions floating around. One I saw from OxyBlue, I thought it was, suggested using 1/3 can and letting sit about 20 min. Also your looking to not stall it out although you will certainly cause some sputtering.

    I've done this 2X now and I get a crap load of gunk out if the smoke is any indication and no CEL's

    We've always used it to stall out at the end, this way there is enough sitting in the cylinder to loosen the carbon while sitting. Never had any SES lights on any vehicles we done over the years.
