Once you’ve stopped, the majority of modern cars cannot be restarted while the AdBlue tank is completely empty. Fortunately, this situation is easily avoidable, as AdBlue refills are straightforward and usually relatively cheap if you shop around and do them yourself. When your SCR-equipped vehicle’s AdBlue levels are running low, a warning alert will appear on the dashboard. If it runs out of completely, the car will lose power and reduce its emission in line with legal standards. Its performance will be returned when its AdBlue tank has been replenished. It can be found in urine most commonly, but is also produced by some moulds and fungi. The human body produces urea from the liver, when it breaks down proteins and amino acids.

[7] Once hailed as an eco-friendly alternative to petrol thanks to its relative efficiency, diesel soon lost its lustre thanks to a series of scandals in 2015 known as Dieselgate in which Volkswagen and a number of other manufacturers were found to be cheating on emissions tests. The scam involved the fitment of cheat devices that could recognise when cars were being tested, which resulted in emissions figures much lower than the cars actually produced under real-world conditions. Since then, partially as a result of the rise of the electric car and more economical turbocharged petrol engines and partially due to a total loss of public trust in diesel, sales of diesel cars have been on a precipitous decline. Diesel sales fell by more than 48% in 2021 compared to the previous year and diesel cars are now comfortably outsold by electric models.

If your car is due a service within the next 1,000 miles or so, it’s probably alright to wait for your mechanic or dealer to top up the AdBlue. If not, however, drivers should do it themselves as soon as possible. What should I do if I put diesel in the AdBlue tank?
