It’s been a non-stop few weeks here at Coastal Motorsport in North Walsham, with everything from DPF cleaning to custom remapping coming through our doors. One of the big issues we’ve been tackling lately is AdBlue problems – something that affects a lot of modern diesel vehicles.

What is AdBlue?

AdBlue is a fluid used in diesel engines to reduce emissions, injected into the exhaust system as part of the SCR (Selective Catalytic Reduction) process. When the system works, it helps your vehicle stay environmentally compliant.

Common AdBlue issues

Unfortunately, AdBlue systems can be temperamental. The most common problems we see include:

• AdBlue warning lights that won’t clear
• Blocked injectors or crystallisation inside the system
• Incorrect fluid quality sensors giving false readings
• Reduced engine power (limp mode) caused by AdBlue system faults

How we fix AdBlue problems

At our North Walsham workshop, we use professional diagnostics to quickly identify the root cause. Depending on the issue, we can:

• Clean or repair AdBlue injectors
• Reset the AdBlue system after faults
• Update or remap the ECU where appropriate
• Provide preventative maintenance to avoid repeat issues

By fixing the fault properly, we help you avoid costly main dealer bills and get your car back on the road fast.

More than just AdBlue

Alongside AdBlue system repairs, we also offer:

• DPF cleaning – restoring performance and efficiency
• Custom ECU remapping – unlocking more power or economy
• Servicing & repairs – keeping your car safe and reliable year-round
