2.0 TDI 170 Fuel Consumption

[prolfe]

It must be an abnormality with the both of your engines. As in mine it is so easy to hit high forties, low fifties.

As for the petrol, you really do have to drive like a grandad, just to hit 35mpg let alone give it some stick.

I drove my '07 A4 TDi 170 SE Avant like a 'grandad' today and it managed all of 41mpg, admittedly it was into a headwind at times but I even had the aircon off (never run a previous car without the climate/aircon on auto all the time and always beat manufacturers claimed figures).

Daren't use the cruise either as this makes matters worse..... Got 44mpg out of it on a 200 mile run last week but had to stick to 65-70mph without cruise or aircon - not happy since HMRC reckon sub-2.0l diesels can do a 47mpg average.

I'm kicking myself because when Audi lent me a car for a 2-day test drive last year, that only managed 40mpg and had averaged 41mpg in 6K miles according to its trip computer (spookily what mine has averaged in 13K miles). I naively accepted the dealer's 'there's something funny about that car' explanation.

I keep telling myself it's getting better but I'm glad I only leased it for 2 years, very disappointed - I used to get 38mpg out of my 1999 A4 1.8SE 6 years ago whilst running the climate /aircon constantly.

I guess I'll ask a dealer but had been hoping to merely visit them for servicing since nothing has gone wrong (except steering noise). Expect they'll no-doubt suggest it's down to 'driving style' ?

Oh well, rant over....

My beef is, how have VW/Audi managed to go from having the most efficient diesels, to diesels which barely have any MPG advantage over petrols considering the additional cost. To get even 45 mpg out of my car I have to drive it so gently and never use the CC, its just unreal, in my old 1.9 TDI 130 I could get high 40's average MPG using the CC most of the time !
