How will you know if AdBlue needs topping up?
Your information display screen should flash up warnings, much as it would if fuel or windscreen washer fluid were low.
Can drivers refill AdBlue themselves?
Garages should refill AdBlue as part of a diesel car’s routine servicing. However, if your warning light comes on, it is best to get a Unipartner garage to top it up as overfilling can create a vacuum in tank preventing the AdBlue being injected into the exhaust.
What happens if you run out of AdBlue?
If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to limit its emissions. Once you’ve stopped, you won’t be able to restart the engine if the AdBlue tank’s empty.
