Your van gulped a full 10-litre can of AdBlue last week, and the dash already wants more. At £15 a fill that stings—but the real worry is a looming no-start lock if the SCR ECU believes fluid is vanishing without lowering NOx. RAC’s 2025 fleet study shows abnormal AdBlue use…
Dash shows a yellow AdBlue lamp and a countdown like “No start in 500 miles” or “Service AdBlue”? Even with a full tank, some vans refuse to fire once the lock is active. The good news: **not every case needs parts**. This guide explains why it happens, what you can…
The AdBlue tank is meant to be a fit-and-forget component: top up with ISO-22241 fluid and drive. Yet fleets that store vans outdoors or buy urea in bulk drums sometimes end up with waterlogged or crystal-filled tanks. When conductivity drifts or sludge blocks the pickup screen, the ECU logs P20EE…
-3 °C at 6 a.m. on Victoria Road, windscreen white, courier deadlines calling. You key the Sprinter and the blue light joins the crackling frost: P13DF – heater circuit open. No heater means thick, jelly-like urea that the pump can’t pull, and the countdown to “No start” begins. Each winter…
Own a Sprinter? You’ve probably seen the blue DEF lamp at the worst possible moment—loading pallets in Longton or queuing for fuel on the A50. Since 2021 I’ve cleared 250+ Sprinter AdBlue faults across Staffordshire. Below is the crib-sheet I keep in my van: what each code means, quick checks…
You climb into the Crafter at 6 a.m., slap the key round and—bam—“NO START IN 500 MILES” glares back. Panic follows: Will I make the Stafford run? How much is a new tank? Relax. That blue countdown is a software trip-wire, not a death sentence. In most cases a top-up…
What Euro 7 demands Euro 7 sets the bar higher than any standard before it. The headline figure: 60 mg/km NOx – the same target petrol cars already meet. :contentReference[oaicite:0]{index=0} Real-world tests up to 200,000 km instead of lab-only checks. On-board emission monitors that ping authorities if levels creep up.…
AdBlue pump fault vs heater fault – quick roadside checks Your dash throws up the blue DEF light, the miles-to-no-start count clicks down, and the delivery run to Fenton suddenly looks shaky. Before you panic-order a new tank, spend five minutes with a torch and, if you have one, a…
Citroën and Vauxhall vans are some of the most common we attend for AdBlue-related faults. Codes like P20E9 (reductant pressure too high) and U029D (lost communication with the NOx sensor) can put a van into limp mode or start a no-start countdown at the worst time. Here’s a clear guide…
When AdBlue faults strike, van owners are often left with two choices: book into a garage or arrange a mobile AdBlue repair. Both have their pros and cons, but which option makes the most sense in 2025? Let’s compare them side by side. What Is a Mobile AdBlue Repair? Mobile…
