What to do if you put AdBlue in a diesel tank
Four quick steps before AdBlue removal. Get the car safe, then get us on the phone.
01 Leave the ignition off
Do not turn the key after putting AdBlue in a diesel tank. Water and urea must not enter the fuel pump.
02 Tell forecourt staff
Ask for help to push the car clear of the pumps if you are still on the forecourt.
03 Move somewhere safe
Get the vehicle out of traffic. Share a road name, postcode, or shop name when you call for AdBlue removal.
04 Call Fuel Flush
Call 07933 620 900. We confirm your location and dispatch an AdBlue removal van.
AdBlue in your diesel tank? Do not start the engine
Turning the key after putting AdBlue in diesel can push water and urea into the pump and injectors. Keep ignition OFF and call Fuel Flush for immediate AdBlue removal.
Call 24/7: 07933 620 900What happens when AdBlue goes in a diesel tank
AdBlue is a water based urea solution made for the exhaust SCR system, not the diesel fuel tank. When AdBlue goes into diesel fuel it can corrode parts and crystallize in lines, pumps, and injectors. Fuel Flush provides emergency AdBlue removal, tank flushing, and clean diesel refill across Cheshire, Merseyside and Greater Manchester.
- Emergency AdBlue removal for cars, vans, and light commercials
- Forecourt-safe tank flushing equipment
- Most AdBlue in diesel jobs take 30 to 45 minutes on scene
AdBlue is mostly water
Water in a diesel fuel system can damage high pressure pumps and injectors very quickly.
Urea can crystallize
As AdBlue dries it can leave crystals that block fuel lines, filters, and injectors.
Fast AdBlue removal limits damage
Prompt AdBlue removal and tank flushing usually prevents a much larger repair bill.
