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
