At KernowSport, we get to work on all sorts of rugged 4x4s—Ford Rangers, VW Amaroks, Subarus and plenty more. Although we don’t see quite as many Nissan Navaras, we’re always keen to help Cornwall’s pickup owners keep their vehicles performing at their best. Recently, a customer in Longrock contacted us with an AdBlue countdown warning on his Nissan Navara. With the vehicle at risk of going into limp mode, he needed a quick and reliable fix. Despite the onset of a proper Cornish winter—bleddy freezing, rain sideways!— we grabbed a warm coat, fired up the diesel heater in our trusty mobile workshop (the faithful Ducato), and headed out to get the job done. A Fast, Effective Navara AdBlue Solution This AdBlue fault turned out to be one of the quicker ones. Within an hour, we had the Navara diagnosed, reset, and back on the road without countdown warnings or AdBlue performance issues. Whether it’s AdBlue faults, DPF problems, ECU diagnostics, or general 4×4 performance checks, our mobile service covers Longrock, Penzance, Hayle, St Ives, Helston, Redruth, and beyond. Why Cornwall 4×4 Owners Choose KernowSport If your 4×4 is showing warning lights, countdown notices, or performance loss, don’t put it off—early

Another day, another Stellantis-based van with an AdBlue issue — one of the most common problems we see here at Kernowsport. This Vauxhall Combo 1.5D from Penryn came to us with the dreaded AdBlue no-start warning, something we’ve seen dozens of times before. The same problem affects a whole family of vans built under the Stellantis group, including the Peugeot Partner, Citroen Berlingo, and Fiat Doblo — all sharing the same Renault-derived 1.5D engine and ECU platform. 🔧 Common Stellantis AdBlue Issues The AdBlue systems on these vehicles are notoriously unreliable. Owners often experience: Even when the AdBlue tank is full, the car can still go into no-start mode, leaving drivers stranded. At Kernowsport, we specialise in resolving these problems properly — at the ECU level — ensuring the fix is permanent and not just a temporary reset. You can learn more about how we do this on our AdBlue Delete & Repairs page. 🛠️ The Penryn Combo Fix This particular 2019 Vauxhall Combo had been problematic for months, throwing up repeated AdBlue warnings before finally refusing to start altogether. We’ve done so many of these that we could probably remove the ECU blindfolded! Thankfully, it’s one of the easier

At Kernowsport, we often get calls for help — especially when customers are facing urgent AdBlue issues. Whether it’s a countdown warning or a complete no-start problem, these faults can bring life to a standstill, especially for people who rely on their cars for work, school runs, and daily errands. This weekend’s job was exactly one of those cases. Late on Saturday night, we received a call from a worried Jaguar XE owner in Launceston, whose car displayed a dreaded “46 miles until no-start” message. With a long commute to Davidstow for work and no backup vehicle, the situation was urgent. 🔧 Emergency AdBlue Fix in Launceston By Sunday morning, we were on the road — a 160-mile round trip from our base in Hayle — ready to get this customer back on track. Launceston is one of Cornwall’s more isolated towns, and without a working car, getting to work or running errands becomes nearly impossible. That’s where our mobile AdBlue repair service comes in — we bring the workshop to you. We’ve worked on plenty of Jaguar AdBlue systems, and they’re usually straightforward to fix. But this Jaguar XE Diesel decided to keep us on our toes. The ECU

Another day, another AdBlue delete at Kernowsport! We’re seeing more and more Vauxhall Combo, Citroën Berlingo, Peugeot Partner, and Fiat Doblo vans with AdBlue problems — and it’s easy to see why. These vans all share the same Stellantis 1.5D engine, which is becoming notorious for AdBlue system faults even at low mileages. This particular Vauxhall Combo 1.5D, based in Carharrack, came to us with a no-start issue after the dreaded “AdBlue countdown expired” message. For a work van, that’s more than just inconvenient — it means lost income. ⚙️ Why AdBlue Problems Are So Common in These Vans The 1.5D engine, fitted across Vauxhall, Peugeot, Citroën, and Fiat vans, seems especially prone to AdBlue system failures. We’ve seen issues occur with as little as 40,000 miles on the clock. Common symptoms include: Even when serviced correctly, these systems can fail due to sensor crystal build-up or electrical faults. That’s why AdBlue deletes are one of our most requested services. If you’re having similar issues, check out our AdBlue Delete Services to learn how we can help. 🧰 Quick Fix, Professional Service At Kernowsport, we’ve worked on so many of these Stellantis-based vans that we could practically remove their ECUs

At Kernowsport, we know that AdBlue issues can strike at the most inconvenient times — especially when your vehicle is counting down the miles to a complete no-start condition. Today we were called out to two last-minute AdBlue panic jobs in Cornwall: Both drivers were understandably concerned — but thanks to our specialist tools and experience with AdBlue delete and repair services, we were able to get both vehicles sorted quickly and back on the road the same day. ⏱️ Why You Shouldn’t Ignore the AdBlue Countdown If you see an AdBlue countdown warning, it’s essential to act fast. Once that countdown hits zero, your vehicle will refuse to start until the fault is fixed — which can be disastrous if you rely on your car or van for work. Our advice at Kernowsport is simple: “Don’t wait. If topping up the AdBlue tank or flushing the sensor doesn’t solve the issue, get it checked professionally as soon as possible.” We’ve seen many cases where a 1,000-mile countdown suddenly drops to zero without warning. Modern vehicles, especially Citroën, Peugeot, VW, and Ford diesels, are particularly sensitive to AdBlue system faults. Learn more about our AdBlue Delete and Repair Services for

At Kernowsport, we often help visitors to Cornwall get back on the road quickly when unexpected vehicle issues strike during their holiday. This recent job involved a VW Sharan 2.0 TDI staying at Carnon Downs Holiday Park, where the owner, Jo, had been struggling with persistent AdBlue system faults. Diagnosing the AdBlue System Fault Jo had first contacted us back in July after multiple failed attempts elsewhere to resolve her AdBlue issue. By the time we arrived, the Sharan’s dashboard was showing the dreaded “No Start in 100 miles” countdown — something no driver wants to see while away from home. Fortunately, we were finishing up another job in Porthtowan, so it was just a short trip over to Carnon Downs. Once there, our diagnostic tools confirmed that the AdBlue system had a fault that could be corrected on-site. 👉 Learn more about how we fix these systems on our AdBlue Delete and Repair page. Uncovering an ABS Sensor Problem While working through the diagnostics, we noticed that the Sharan had multiple warning lights on the dashboard. Jo suspected they were all related to the AdBlue issue, but further investigation revealed a faulty ABS sensor as a separate problem. This

At Kernowsport, we’re no strangers to helping drivers keep their adventures on track. Recently, we received a call from Lisa, whose Nissan Navara had developed an AdBlue countdown fault while staying at a campsite near Wadebridge. Lisa and her partner were preparing for an incredible road trip across Europe, with plans to tour through Romania — but their Navara wasn’t going to get very far with the countdown threatening to disable the vehicle. AdBlue Fix for the Nissan Navara The morning we arrived, Cornwall treated us to a crisp, cold start. The countryside setting of their campsite was stunning, but the Navara needed attention before the journey could continue. Luckily, this particular Navara was one of the more straightforward AdBlue delete jobs. Within a short time, we had resolved the issue and ensured the vehicle was running reliably again. 👉 If you’re experiencing similar issues, our AdBlue delete service covers everything from Nissan 4x4s to Mercedes cars and even commercial vans. Ready for the Road Ahead With the AdBlue system issue sorted, Lisa and her partner were able to continue preparing for their European adventure with peace of mind. It’s always satisfying to know we’ve played a part in helping
