AdBlue in the Fuel Tank: A Modern-Day Nightmare
A newer problem on the scene is accidentally pouring AdBlue into the diesel tank. AdBlue is a urea solution used in modern diesel cars to clean up exhaust emissions. It's not a fuel additive and has its own, usually blue, filler cap right next to the main one, making mistakes all too easy.
If AdBlue gets into your fuel system, it’s catastrophic. It’s highly corrosive to the seals, sensors, and pipes in your fuel system. Worse still, it can crystallise when it dries, causing rock-solid blockages that can destroy everything from the fuel pump to the injectors.
If you even suspect you've put AdBlue in the wrong place, do not turn the key. The damage can be immediate, extensive, and incredibly expensive to put right.
