AdBlue in Diesel Tank Repair Cost | What Is AdBlue and Why Does It Matter?
AdBlue is a liquid solution made of urea and deionized water. It is injected into the exhaust system of diesel vehicles to reduce harmful nitrogen oxide emissions. While essential for meeting environmental standards, AdBlue must be handled carefully. It is stored separately from diesel fuel and should never mix with it.
Contamination happens when AdBlue accidentally enters the diesel tank. This can occur due to:
Filling the diesel tank with AdBlue by mistake
Faulty or damaged filler caps and seals
Cross-contamination during refueling at forecourts
When AdBlue mixes with diesel fuel, it causes chemical reactions that damage the fuel system, injectors, and engine components.
Signs of AdBlue Contamination in Your Diesel Tank
Detecting AdBlue contamination early can save you from expensive repairs. Common signs include:
Engine warning lights related to emissions or fuel system
Difficulty starting the engine or rough idling
Loss of power or poor acceleration
Unusual noises from the engine or fuel pump
Visible residue or crystals around the fuel filler neck
If you notice any of these symptoms, contact a specialist immediately. Forecourt Rescue Suffolk provides 24/7 assistance at phone number 01473 875186 to diagnose and fix these issues.
