Hi all i have a 2005 mk2 octavia 2.0tdi BKD dsg engine finally got it on vcds scan to see if any fault codes which there wasnt.The cars been recently serviced replace the fuel filter and air filters oil etc.Ive seen a few posts about regarding various sensors having faults which could cause poor mpg return.Around town id say im getting around 25 and on a run 30 at a push ive copied and pasted the results which i received off the guy who scanned the car
