Frequently Asked Questions
AdBlue is a fluid made from urea and deionised water. It’s used in modern diesel vehicles with Selective Catalytic Reduction (SCR) systems to reduce harmful NOx emissions. Without it, your car can’t meet emissions regulations and may not run properly.
Your dashboard will alert you with a warning light or message when AdBlue levels are low. It’s best to top it up as soon as possible – if it runs out, the car may refuse to start.
Yes, you can buy AdBlue at fuel stations or auto stores and top it up yourself via the blue filler cap (usually near your diesel cap or in the boot). Just be careful not to spill it – it can be corrosive. If you're unsure, we’re happy to do it for you.
If AdBlue runs out completely, most cars will enter a no-start mode – meaning the engine won’t restart until it’s refilled. Best to avoid letting it get that low!
It depends on your driving habits and vehicle model, but as a rough guide, most cars will use 1–2 litres of AdBlue every 600–800 miles. We recommend checking it at every service or oil change.
It could be a sensor issue or a software fault. Some cars need a short drive before the light resets, but if it stays on, we can run a diagnostic check to find the cause.
That’s crystallised AdBlue, often caused by spillage or evaporation. It can clog sensors and injectors if not cleaned properly – we can remove build-up and check the system for damage.
Yes. AdBlue should be stored in a sealed container, out of direct sunlight and extreme temperatures. Contaminated or expired fluid can damage the SCR system and trigger faults.
We check AdBlue levels and top up as part of most regular services – but if you’re unsure or need a quick refill, just pop in and we’ll sort it.
Absolutely. We carry out diagnostics, reset software, replace sensors, and clean or repair injectors – whatever your system needs to get back to full working order.
