______________________________________________
Tac has identified an issue with the 9-3 B207 XWD service replacement T8 engine control modules that will only allow the fuel gauge to display ½ tank of fuel anytime the fuel gage is half full to completely full. The gage works correctly from ½ to empty and no customers have ever reported running out of gas due to this issue. Until we have identified and corrected the parts stock, we do not recommend replacement of the T8 unless it is absolutely necessary to fix the vehicle.
If the T8 is replaced on a XWD 9-3 the fuel gage will stay at ½ anytime the fuel tank is half full to completely full: the gage works correctly from ½ to empty.
This is an adaptation of TA248-1108 Check Engine lamp illuminated and DTC P1681, P0638 and/or P2135 set. Once stock has been rectified this document will be removed from IRIS.
