What happens if you put AdBlue in the diesel tank?
AdBlue in the fuel tank contaminates the fuel system and can damage the pump, injectors and lines — it must not be run through the engine. Don't start it; the tank and system need draining and flushing.
In an emergency: don't start the engine and call 0800 170 0644. We drain the wrong fuel on-site, 24/7, 365 days a year.
