Where do i start...lol
Bought a q5 2.0 tdi s-line s tronic 160k full service history. 1st had cambelt and full service done for peace of mind...noticed was putting twice as much fuel as my old a6 2.7tdi...had remap done...was very responsive but fuel consumprion still as bad...took to garage...so far had dpf knocked through and had economy map put on with dpf and egr mapped out...mpg was just as bad...went back to garage..injectors tested...marginal..but paid for new nozzles ro be fitted..mechanic rekons mpg better...picked up car as had to drive london for new year...reset mpg as hit m40...over the 130 miles with no traffic and steady 75mph the avg mpg was a terrible 34mpg
What else could be wrong as fed up chuckin money at a car that should have fairly good mpg
