    Poor MPG on 1.6TDI Sport!!!

    I picked up a second hand 1.6TDI A3 Sportback, 59 plate, one of the main reasons for choosing this model was the attractive MPG that I was supposed to get with the car! I travelled over 100 miles with mainly motorway but a varied journey. I only got 48 MPG for an average of the journey, I was expecting at least 55 ish!!!!

    Is this normal for the engine?

    Any advice would be appreciated!

    they say its not that economical as Audi claims. Did you read any reviews prior to buying the car?

    Not in depth reviews, no! With Audi advertising an average of 68MPG I presumed I would get there or there abouts! Not 20MPG less!

    i haven't used a full tank of diesel yet so will record the actual miles from a full tank.

    The car is due for a long life oil change in 4k miles but might do it now, would this make a big difference?

    I didn't go over 80 on the motorway part of my journey. It was too cold for start / stop to be activated!

    maybe it's my driving style, I normally drive a 2001 Audi A4 2.0 petrol. Even this car gives me 35MPG on average!

    Advertised MPG should be taken with pinch of salt.
    IMHO, for good mpg from a car this size/weight, engine needs to develop around 140bhp.
    Sadly you've been caught out...

    Landrover Evoque Diesel Auto is claimed to give around 44mpg, but real world figures dips to around 32mpg...

    My previous car Mini Cooper Diesel Auto returned around 50 ~ 55 mpg, depending on weather temp.

    Do you think the new A3 1.6 TDi will achive 74mpg in normal driving????? I doubt it...

    New air filter will make a bigger improvement.

    2-3mpgs? Never heard of any diesel engine to benefit a lot from fitting aftermarket filter unless BT is fitted.

    Audi are quite prepared to give a 30% leeway on the consumption figures.With a quote of 68mpg, i would expect in real time about 40.And the oil change will make no differance either.Didnt on my 2.0 170 a4

    Cold weather, old diesel, old oil, DPF burn off's, all contribute to sh*te MPG. Diesels also take about 15K to free up and run best.

    MPG tests are done on a roller with simulated Coefficent of friction so it's a stick in the ground at most, If your light on the loud pedal and use the fuel cutoff as much as possible (pre empting the need for stopping by coming off the throttle early) you should be able to get the combined figure.

    In my highly uninformed opinion, the 1.9 TDi would have been the one to go for. The 1.6 might be a tad underpowered, which means you end up using a bit more right foot than you realise. Pals of mine with the 1.9 diesel lump in the Golf's are returning very impressive mpg numbers.

    Driving to and from work I was amazed how much of a difference the outside temperature makes. Also if your new to the car it might come up a bit once you get used to where its MPG sweet spots are!

    My MPG has gone down a little since the remap due to the right foot being heavy! But am still returning 50+ when careful on motorways

    2.0TDi PD 140 (180ish)

    As the temperature this time of year is cold/dense there will be more air being crammed into the engine, this in theory means that the engine is likely to be adding more fuel... Or am I talking tosh?!!

    I agree with this. It's a small engine for a relatively heavy car.
    Big engines FTW. When I'm on an economy drive it's 2nd, 4th, 6th without reving past 1500

    In my 1.6TDI I get on average 60MPG on my commute to and from work, 30 miles motorway and some back roads, all at about 50-60mph. From experience you won't see anything near that at 80mph! Try drop it down to 70, apparently some engines use 20% more fuel at 80.

    Thanks for all the comments and advice. I have got it booked into audi for a diagnostic but from reading your posts I am guessing they won't find anything wrong. I will change the oil and air filter and see if I get squeeze anymore out of it!

    i am just a bit miffed with audi falsely advertising these figures! Naive I know! Rant over!

    Re: Poor MPG on 1.6TDI Sport!!!

    try laying off the pedal a bit.

    what revs are you sitting at ? over 2000 Id imagine

    try dropping your speed of 80mph to 60mph or around 1600-1700 revs.

    try that over course of a tank and work out your avg

    Also try millers diesel treatment for 10 fill ups it will give you a bit more bhp and clean the injectors aswell i use it on all fill-ups.

    Do not waste time or money changing oil.. Do you think you'll recoup the cost in fuel saving?

    Unlucky purchase. I had a right set to with Audi over my 1.6TDI. I got one when they first came out. Ran it for two years and was more than pleased to see the back of it.
    The computer may tell you it's returning 50+, I can assure you when measured at the pump (Which I kept record for EVERY tank fill) you will be lucky to get 50!! Mine averaged 48MPG over 72,000 miles !!! nothing like the book says. I had it checked by Audi dealer 3 times, and once by an Independent and all said engine was running perfect. The car was serviced by Audi regular, Tyres and alignment changed and checked regular, I even changed driving styles to see if it made any difference. I did run it with 245 x 45 x 18" wheels and that added about 5mpg!!
    I now have a 2.0TDI 170 BE S-line DSG....MPG...consistently 50+mpg along with some exciting driving
