golf fuel economy

What kind of journeys are you doing your engine should be more efficient with cold air, especially on cold damp mornings, thats why they put intercoolers on diesels.

Just noticed that my mpg has turned sharply downwards with the onset of the cold weather but only to be expected.

I don't know if this is relevant in any way but I have noticed that my car does take a long time to reach operating temp.

Hi, I have exactly the same problem - low mpg, and takes longer to reach operating temp. I've recently had the coolant tank/sensor replaced - would this cause fuel usage to increase?

Also had 3 new tyres.

And finally had the engine temp sensor replaced too.

I get 30mpg local town driving (used to get 40ish), and get average 45mpg motorway (used to get 50mpg at least).

I had the MAF replaced about a year ago - would this be a contributing factor to mpg, as the car is still rapid.

can you reset the average MPG or is that the reading from new.

Alan - the readings are from new. The trip 1 (from 1 cold engine trip, which is reset automatically) reads on average 30mpg local town driving average 45mpg motorway.

The trip 2 (total until reset manually when I re-fuel) has read between 42-45mpg for the past 4 refuels, which I had alot of motorway driving too.

i get roughly the same on the 42-45 but it can go to 55-60 on a run upto the lakes

I get pretty much the same mileage (low 40's) as my old man in his 2.0 diesel merc on similar roads. I'd say that unless it's throwing a code, then it's prob the type of roads & how much throttle has to be used to navigate them.
