Compare Subaru AdBlue repair quotes from specialist garages

Subaru is known for using the innovative boxer engine, named for the horizontal movement of the pistons - almost like a boxer throwing punches. The flat layout of this engine provides better fuel efficiency, and its low centre of gravity makes it more responsive.

In the 2020 Driver Power Survey, Subaru was voted the best manufacturer for safety features for the second year running. And it isn't just cars that Subaru manufactures - it also has an aerospace division that develops and creates parts for planes, including Boeing's 777 and 787 passenger jets.

AdBlue is a diesel exhaust fluid sprayed in small amounts onto exhaust gas, turning the NOx into less harmful nitrogen and water. If your car runs out of AdBlue while driving, its performance will be significantly reduced; when you stop the engine, it won't start again until you refill the tank.

Pump failure is one of the most common issues associated with the AdBlue system. Fortunately, an AdBlue pump repair or replacement isn't usually costly. Other problems include contamination and failure of the nozzle, NOx sensor and the AdBlue control unit.

You'll need to book an AdBlue system repair if your car develops any of these faults. Most of the time, the mechanic will run an AdBlue fault diagnostic first. Booking a car AdBlue service, which involves a top-up of fluid and a general check of the system's components, can help prevent the above issues.
