  1. Second Generation Faults & Fixes
    Really at wits end with my 2011 R56 Cooper S. It's been experiencing a very sporadic misfire issue. It's happened about 6/7 times now in the past 8 months and every time it has been after 1 hour of motorway driving, constant speed 70mph and only once after 20 mins (still motorway driving)...
  2. MINI Faults & Fixes
    Hi All First post, so go easy... :) I have an R56 Mini with the N12 1.4 petrol engine (Non Turbo) with 70000 miles, that has developed a misfire.

    Hi everyone, hope were all okay 😊 Just picked up a used Mini cooper s r56 2007. Absolutely loving the car so far. Buying it used I expected some issues.

    My 2012 mini cooper s began shaking the other day while I was driving and didn't have full power. I checked to see what it was and I got the P0301(cylinder 1 misfire) code.

  6. MINI One
    I changed the spark plugs as part of a service on my 2003 mini one, ever since then it started misfiring and stuttering etc.. I put the old plugs back in to check the plugs weren’t at fault and it’s still doing the same, I just run a compression test and as I pulled the plugs out plug number 3...

    When accelerating our 2010 Mini 1.6 D gets to 2300 revs it gives a severe jolt, it's like switching the key off and on really quickly. It happens when it up to running temp, it accelerates smoothly up to 2300 gives a big jolt then continues on smoothly. There are no fault codes and a local...

  9. Second Generation Faults & Fixes
    So - My 2007 Mini Cooper S (1.6 Turbo) Has developed some rather strange symptoms, it will run completely fine one day, full of power, no misfire and heating is really hot.
