When our roadside assistance team was called out on the A1 near Grantham, the truck was completely stopped due to an engine power limitation. After a quick but thorough diagnostic check, the root cause was identified: the AdBlue system was blocked with crystallized AdBlue. This is a common issue for heavy-duty trucks when the AdBlue system is not serviced regularly or when low-quality AdBlue fluid has been used.
What We Did
Our mechanics carried out a full AdBlue cleaning procedure:
- The entire AdBlue installation was cleaned and flushed.
- The system was bled to remove air and ensure proper fluid circulation.
- The engine power restriction was removed.
- A complete AdBlue system check was performed to confirm that everything was back to normal.
Why AdBlue Cleaning Matters
Crystallized AdBlue can cause serious damage to the SCR system, injectors, and sensors. Without proper cleaning, the truck may lose power, enter limp mode, or even fail roadside inspections. Regular AdBlue cleaning and maintenance prevents expensive repairs, ensures compliance with emissions standards, and keeps the vehicle running efficiently.
Outcome
After the AdBlue system cleaning, the truck was fully operational again. The customer was very satisfied and able to continue the journey without further delays.
