Winter AdBlue Problems: Freezing Tanks, Heater Faults, and Mobile Fixes

As winter sets in across Stoke and Staffordshire, more drivers find themselves stuck with AdBlue freezing problems or heater faults. A system designed to cut emissions can easily leave your van in limp mode on a frosty morning. Here’s how to spot the issues, why they happen, and how our mobile team gets them fixed fast.

Why AdBlue Freezes in Winter

AdBlue is a urea solution that begins to freeze at around -11°C. In UK winters, especially overnight, this can cause the liquid in the tank and pipes to solidify. If the AdBlue heater doesn’t kick in properly, the SCR system can’t dose correctly, which leads to warnings or even no-start countdowns.

Common Winter Faults

• Frozen AdBlue tank: The fluid won’t pump, leaving the system in fault mode.
• AdBlue heater failure: The tank heater fails to warm the fluid in cold weather (read more here).
• Pump faults in low temperatures: Cold starts can trigger pump vs heater error codes.
• No-start countdown: Warning messages like “No start in 500 miles” can appear when the system can’t function (see guide here).

Signs Your Van Has a Winter AdBlue Issue

Some of the warning signs include:

• Cold morning starts triggering engine warning lights.
• AdBlue consumption suddenly dropping to zero (frozen system).
• Heater fault codes logged in diagnostics.
• Vans refusing to start after being left overnight in freezing weather.

How Mobile Fixes Work

With our mobile service, there’s no need to book into a workshop. We come to your location across Stoke, Newcastle-under-Lyme, Stafford, and Crewe to reset the system, replace faulty components if needed, or carry out a full AdBlue delete where required for off-road/export vehicles.

Most jobs are completed within an hour, meaning you can get back on the road the same day — even if your van refused to start that morning.

Preventing Winter Problems

There are a few simple steps to reduce the risk of winter AdBlue issues:

• Keep vans parked under shelter or indoors where possible.
• Avoid letting the AdBlue level run too low, as small amounts freeze faster.
• Book a system check before the coldest months to test heaters and pumps.

If you already suspect a weak heater or pump fault, sorting it before the temperature drops can save you a costly roadside breakdown.

Legal Position in 2025

For UK road vehicles, heaters and pumps must remain functional to pass MOT checks. Euro 7 rules have tightened requirements further, meaning it’s vital to keep SCR systems working if the van is staying on public roads. We also provide resets and repairs to help drivers remain compliant.
