38mpg round town from a 10+ year old 2.0 diesel? Sounds fine to me?

Around town the figures are not that bad. But as said maybe a service is needed :-)

Erm... Move to the country? Town driving is shit for diesels, I'm getting 36mpg round town in my XUD. They take ages to warm up so they use more fuel, a cold engine is far less efficient.

Town stop-start driving is where you need a 1.0 petrol or a 0.5 petrol (Smart car!)
Unfortunately the 2.0 diesel is more at home sat on the motorway chugging along!

Its also colder now which doesn't help 
How many miles is the car at? If the EGR was working you may actually lose some efficiency.

I once managed 23mpg out of a 306! But it was a 1.8 Cabriolet (heavy) with GTi6 manifolds and camshafts and I only worked 6 miles away!

Pfft, the slow HDi only does 50mpg. Hoping that gets better after the service yesterday though!
The golf on the other hand.....

EGR should give a quicker warm up time....increasing efficiency! But they do get full of crap or stuck open over time which can obviously reduce efficiency.....try plugging it back in for a week and see what happens?
