How often do I need to top up AdBlue®?

The exact answer depends on your individual driving style, vehicle load and engine. 

That said, you should be able to cover approximately 2,485 miles before your tank hits empty, if your car's equipped with our 2.0 CDTi engine, or as much as 4,038 miles in the case of our 1.6 CDTi.

Whatever the range, an indicator built into the on-board computer will warn you when the fluid level is getting low and you need to top up.
