Reduced MPG since belt change.
Posted: Thu Nov 17, 2016 1:46 pm
Hello guys,
I took my B7 2013 sport into VW main dealer for a belt change, I signed a declaration to stop them updating the software, however since the change, my average tank to tank MPG has dropped from 52 to 46. Generally, it feels less spritely, sluggish in 6th etc. Two tanks of fuel.
So, either they've flashed the firmware against my will or they've cocked up the belt change... or potentially another issue somewhere.
VCDS used to have a timing check option for the old ALH engines of years ago, can it be tested in latest VCDS?
How do I find out which firmware my ECU is now currently running?
Thanks in advance.
