Hello, I got the vag to tell me that my cel is on because of code 17544 - Fuel trim : Bank 1 add : system too lean. Turned off the light and was good for about a week, now its back on. Haven't rescanned it yet but just curious if anybody has had this issue. My tuner shop tells me that most likely bad tank of gas or o2 sensor is broken. Thoughts?

Thanks!

 

air leak mate 17544 P1136 check your hoses and vacuum pipes,

if the CEL dosnt come back on then there is no problem

Cool, thanks for the input. Hope the problem does not persist, can't stand that light being on. I'm sure everybody agrees

 

dude one time a cel came on my car and it ended up that the gas cap was cracked. Dealer said if gas cap isnt tight enough or itis cracked that the light will eventually come on..........weird
