Hi

I own an 2002 A4 Quattro Sport 1.9 TDi. When I first got her she was returning 50+ MPG and started on the turn of the key.

Then without warning she now takes 3/4 turns (although occasionally will fire up instantly) before firing up and the fuel economy is now:

Urban: 20-22 MPG

Long Distance: 30-33 MPG

Can anyone help. I have been to the local Audi garages, they have changed the Coolant Sensor and done various other tests but seem powerless unless their computers tell them what to do?

Thanks.
