Compare Fiat 124 AdBlue repair quotes from specialist garages

Fiat is known for its small-sized vehicles, like the iconic Fiat 500 and the Fiat Panda, famously one of ex-Top Gear presenter James May's favourite cars. Take a look at our list of top ten cars like the Fiat 500 here.

However, the brand has also branched out from its small-car origins, and in 2023, a Fiat E-Scudo all-electric van set a world record for the longest distance travelled by a van on a single charge, covering just over 311 miles.

Despite the earliest Fiat 500 being released all the way back in 1957, the latest iterations are still making waves, winning 'Best Small Car' at the 2022 Autocar Awards, with its electric counterpart, the 500e, winning 'Best Electric Small Car' at the 2023 WhatCar? Electric Car Awards.

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.
