Hi Steve, Maybe I’m wrong , I just thought with the dpf removed but not deleted , the car would run rough and not at its best. At the moment , I am doing a lot of city driving , occasionally on the motor way . I know bumper to bumper traffic doesn’t help .

Hi everyone , I recently bought a 2007 Audi A5 3.0 TDI Quattro manual . When I got the car it already had a downpipe . I recently got a map. The person who mapped it never deleted dpf from ECU. MPG after the map but before the dpf got deleted was fairly poor , around 24 MPG around the city . About a week ago got the dpf deleted from the ECU and there’s no more check engine light but the mpg has remained the same ? Anything else that is causing my mpg to be so poor ?
