We have replaced the MAF sensor and disconnected the battery and re-connected.
Sprayed the sensors to clean them, still getting this code.
The next thing will be replacing the Intake air temperature sensor. -
Let me check if there is any more information. What model and year is your Audi?
-
Thanks
Its and Audi a3 2009 sportback 1.9.It may help to know that we got code: P0299 turbo undercharge before the MAF sensor change.
-
Unfortunately I couldn't find any other information, other than replacing the MAF.
-
How about the first one?
Turbo supercharger / underboostI reset the service light and this code is now showing, checked for air leaks and disconnected and reconnected MAP sensor.
What's a "normal" MAP sensor reading?
Mine is at constant 29 and my MAF is reading 90°F now.Are these readings normal?
