Hello,I have got Audi A4 Avant 1.9TDI 130bhp S-line Auto(6speed) and i am having a big problem. Read alot of ''Bad Mpg'' titled threads but most of them are about 35-40mpg, if mine would do atlest that, i would be more than happy. car in perfect condition even with 117k miles on clock, always serviced in time with genuine oils and parts. changing my oil,filters every 5k miles(that what i do per year). tyre preasure is 2,2bar (32psi),turbo works fine,new thermostat,however egr has a very minor oil leak. scanned it with computer in one VAG garage : no faults att all, technitian says engine is perfect(he never seen that good condiotion engine on 10year old car with 115k miles on). So,my problem is that I do only 21mpg on 3 mile town trips to work and back (warming engine about 3-5min in morning/afterwork) and 32mpg on motorway 60mil trip to liverpool and back. Here is definately somethign wrong with it. Petrol engines can do more mpg than that, i am very carefull driver 30mph in town and 70mph on motorway very gently. Please HELP! Calculated close as posible (not a newbie at that) that mpg based off full tanks. P.S car smokes alot when cold (whitish smoke),once it warmed up no smoke at all.
