getting this error code, ive read before that it could be due to a boost leak or it could be the fpr hose, i replaced that hose recently but i think the hose i replaced it with may be a little smaller/tighter...

my car smells like rich petrol inside the cabin, also the spark plugs, after just being replaced are showing alot of carbon on them eventually will foul them...

1 Fault Found:
00561 - Mixture Adaptation
14-00 - Adaptation Limit (Add) Exceeded

any tips?

 

I can't find that code in my Bentley, for the US,

However, it is either an oxygen sensor, or the evaporative recirculation system.

 

evaporative recirculation system whats that?

and if it were the oxygen sensor id hope a code would be returned
