I have had a recurring fault code for a year, translated it said "too rich at idle", cancelled it dozens of times but comes back after 150 miles. Put it in Audi main dealership and they said its fuel in the oil....changed the oil and charged me £300, needless to say the light came back on after 150 miles. Incidentally how do they get away with charging £90 to plug VCDS in for 5 minutes ?
Anyway local audi independent had a look and the carbon filter in the breather tank had broken up and part of it was stuck in the solenoid valve so it was stuck open. easy fix, new breather box and valve £180.00 all in.
Just thought i would mention this because at 50k miles and 5 years its an easy thing for people to check themselves if you get the fault code P2188, done 1200 miles since and no light .
