Hey Mini experts out there. Just getting into these vehicles. I just bought my son a 2009 Clubman (non-S). Just changed the Cat/Exhaust manifold & both O2 sensors about a month ago. Car was running great, but now I'm getting Check Engine lights for MULTIPLE codes. The car runs great, no chugging or smoke or hesitation. No weird noises or knocks, nothing out of the normal. I can reset the codes and it will take about a day for them to return, the exact same codes.Where should I even begin to start troubleshooting??

Here are the codes: P0100, P0013,P0010, P0444, P0597, P113b, P0458, 2088, 2090, b2aaa.

 

I think you could start with monitoring the live data. there is a code for the thermostat, so check the numbers on that. do a visual inspection for the timing chain. remove the valve cover and see if it is in time. newtis.info is a great resource for how to's and realoem.com is excellent for part numbers and such.
