~45 seems not too bad. The 320d is probably more fuel efficient than the 320d on A/B road journeys.

Errrrmmmmm well my 325d is only meant to do 47mpg combined, but yesterday at 2 degrees Celsius I drove a 380 mile return trip to Birmingham at 75mph and it returned 54.3mpg, plus I was squeezing the throttle hard on slip roads etc.
