Default e320 cdi fuel consumption and rough idle?

Hello again,

My 2001 e320 cdi (w210) was regularly returning 42+ mpg before the failure of injectors. MB replaced injectors 1 and 3 and returned the car.

I've noticed that the fuel consumption is no longer better than about 35mpg, and when in D the car seems very low on revs as though it's going to cut out - but it doesn't. It's also become very sluggish.

I have contacted MB and they say it can not be the injectors or anything they did.

Any ideas?

Thanks.

Answer - went back to MB and told them.

The injector timinghad not been mapped back to ECU properly (or something like that!).

Anyway, it works now :-)
