Mini Cooper S Convertible R57 2011 Needs Repair

  

Having bought this Mini last year it developed an engine fault after a few months. As it was a second car, I decided to try and fix it over winter. Fast forward to now and I've still not managed it, so decided to let it go and see if someone with more knowledge of these cars is able to.

The car starts first time, but when cold it stumbles and misfires until it warms up. So far I replaced the following. HPFP (High Pressure Fuel Pump) Genuine, not a cheap Chinese version. Diagnostics shows code: 2BC0 Mixture Control Too Lean.

This would suggest an inlet leak, but I can't seem to find anything. Also, the roof will not go fully down.

The sunroof section opens, but it will not go any further. I have not investigated why. Overall the car is in good condition with low mileage for the year, and I'm sure looking at what these sell for in working condition will be a bargain for someone. And please, don't ask what my'best price' is, if you're serious, make an offer.

Note, the car cannot be driven away, it has no MOT.
