227 Fuel trim (Bank 1),O2 control adaptation limit
228 Fuel trim (Bank 2),O2 control adaptation limit
209 EWS, content of message

I Still have no idea what could they be

I have 228 and 227 as well. They mean the fuel adaptation has reached it's limit. The mechanic told me the fuel mixture was to lean and it could be caused by a leak in the air intake system (from the MAF towards engine), crank case vent valve ($600), or O2 sensors. One of the syptoms that is associated with these problems is a rough idle or stalling when stopping after continuos driving.

To rich or to lean codes. You need to look at the additive and multiplicative readings to see if it is rich or lean. Then run some tests from there
