Hello everyone this is my first post. I have had my 2008 mini cooper s for about 8 months now. About a month ago my check engine light turned on and during my service visit last week I had them check the codes. I was very surprised to see so many and I am hopeful that someone can shed some light on them and hopefully tell me that a few of them are related.

The codes are as follows;

2A7F O2 sensor after catalytic converter (electric)
2A56 O2 Sensor after catalytic converter (function)
2B5C Air Mass Sensor plausibility
289E Boost Pressure Sensor electric
2B64 Intake manifold Unmetered air
28A5 Boost Pressure sensor plausibility

Also, could some of these be old codes that have already been taken care of?

Any help is appreciated.

If it were mine, and was running and performing OK, I would clear the codes and see what comes back. I would also check all the intake and turbo hoses for proper fitment, cracks or damage, and loose clamps.

 

Yes, that's a bit strange for all those codes to pop up at once.
