Hi guys,

I have an Audi A3 2012 2.0TFSI and I have codes 101 and 2188 and the miles per gallon has dropped 2 to 3 miles per gallon. I think that the LT FTRM1 is too high.

abslt tps 12.9%
eng speed 762 rpm
MAF 3.80 LB/M
ST FTRM1 -2.3%
LT FTRM1 -21.9%

I have replaced the MAF sensor and DV valve recently. I can also hear a little noise like a whisper under the hook when I accelerate. I have checked for air vacuum leeks with carb cleaner and nothing happened.

I have also checked hoses to the air intake system and the PCV disk. The PCV disk seems that it is fine. I could not check the hoses that it is the output in the throttle bottle because it is not easy to access.

Do you have any suggestion? I will make an appointment with the mechanic.

Thanks!
