I have a 2013 Countryman S (manual) and I have been getting the half engine light and check engine light with code :

P00BD

Thus far have changed the MAF with Bosh OME MAF, both O2 sensors (upstream and down). New air filter and all housings cleaned.

It still runs sluggish, no power, and often dies at idle.

Please help!!!!!

 

Check your intake tube for any leaks after the maf before the turbo. There might be a crack in that tube allowing air in.

 

check the plug going to the MAF. it could be possibly be an intake boot leak but i know mine was cracked for over a month (bought the vehicle in that condition, didn't know to look for stuff like that) and i didn't get a CEL or anything.
