Have you checked this against actual miles to a tank? Computer could be off? Other then that I would check common issues like clogged egr, boost valve and check swirl flaps. Not sure how much these would effect mpg tho?

A few things you can do.

Check for fault codes using the pedal test.

Chean the egr valve.

Here

Clean the boost sensor.

Here

You should see 40mpg on the trip minimum depending on what sort of driving you do.

I might try the EGR deep clean minus the drilling a hole part see if it gets any better. If i have any success i will let you know.

From what ive heard, no in a word. Goes even lower if you really give it the beans.
hmmmm, I average 55mpg motorways and low 40's urban!

Is THAT good?

Also, are Heinz Beans better than say Crosse & Blackwell?

Can't see Netto's 'La Campagna' beans being any good though.

50 and above for motorway journery's is good.

Town driving is roughly 40 - 44.

All depends on how you drive of course.

The heavier your right foot, the lower the mpg figure.
