Injector Change - Worse Fuel Consumption!!!!

I have just had Injector 4 replaced on my 2009 Alfa 159 Diesel, as the car was smoking.

The Fuel Consumption has dropped from a just about acceptable 40MPG to a totally unacceptable 30MPG.

Any ideas. I do a high mileage and cannot afford such poor consumption.

Any advice would be greatly appreciated.

Don't worry about it, it will improve in around 1000 miles, its still learning the new characteristics and your previous built up economy figures are blanked.

On some marques an injector change learn run disables the fuel economy read outs to save freaking the drivers out till its finished the learning runs and trims.

Have you coded the new injector? If not the ecu will use the flow rate of the old injector.
