This job in St Ives was for a local customer who was preparing to sell his Audi A4 Avant when the dreaded AdBlue warnings appeared on the dash. At first, the owner asked us to reset the system in the hope that it would stay clear, but within just 24 hours the warnings returned. Unfortunately, once these AdBlue systems start to go wrong, they tend to continue getting worse. We returned the next day and carried out a full AdBlue delete via the ECU, mapping out the system permanently. While we were there, we also performed a full health check on the Audi to ensure it was in top condition. Happily, this one turned out to be a very clean, well-maintained vehicle — now AdBlue-free and ready to give its next owner many years of reliable service.

The first job of the day took us to Perran-ar-worthal, between Falmouth and Truro, where a 2016 Citroën C4 Cactus was showing the dreaded AdBlue countdown. We’ve worked on quite a few Citroën models recently — including the C4 Picasso, Grand Picasso, and C4 Cactus — and one thing that always amuses us is how the OBD ports are still positioned for left-hand drive cars. They’re on what would have been the driver’s side in France, which always makes us smile when plugging in our tools. After connecting diagnostics and applying the right fix, we were able to clear the AdBlue problem and get Marco’s car back to normal. Over a quick chat, we also shared our mutual love of good coffee — and Marco even left with a few of our personal recommendations for a new grinder! Another AdBlue issue resolved, another happy Kernowsport customer, and plenty more miles ahead for the C4 Cactus.

Job number two today was an unusual one, and unfortunately interesting for all the wrong reasons. We were called to Camelford to look at a Mercedes GLE 350 that was suffering from persistent AdBlue issues. As usual, we carried out our diagnostic work, removed the AdBlue faults, and prepared the ECU fix. All went smoothly until we pressed the start button — and nothing happened. After two hours of diagnosis, testing with various tools, and even putting the original map back on, the cause became clear. Once this particular Mercedes GLE 350 records a “no start” AdBlue error, it cannot be cleared with standard tools — it requires a dealer reset to enable the engine to start again. This was the first case of its kind we’ve come across, and it serves as a valuable reminder: don’t ignore AdBlue warnings. This vehicle had been alerting the driver for more than 800 miles before finally locking itself into a no-start condition. For now, the car will need a trip to Mercedes for the reset. Once that’s done, we’ll return to apply the original Kernowsport AdBlue solution to prevent further issues. Why Fix AdBlue Faults Early? If your Mercedes, Audi, VW, or

Job number two today took us to our good friends at Harts Haulage in Redruth, where a stunning 2018 Ford Ranger was struggling with AdBlue problems. Like many vehicles fitted with AdBlue systems, the sensors can become coated with crystals, causing false readings and triggering dashboard warnings. Left unchecked, these issues can quickly escalate into limp mode or even no-start countdowns. Fortunately, we’ve worked on plenty of these systems before and were able to diagnose and repair the AdBlue fault quickly, getting this 3.2-litre beast back into A1 condition and ready for work again. While we don’t see as many Ford Rangers as we do VW Amaroks these days, they remain a solid choice for trade and commercial use across Cornwall. It does seem that changes in tax rules have made them less common, but when maintained properly, they’re still a fantastic vehicle. Another happy customer, and another smooth fix for Kernowsport.

Today’s job was one of the most challenging we’ve faced at Kernowsport. We were called to Rosudgeon near Helston to resolve a serious AdBlue fault on a 2022 Isuzu Grafter LCV. The dashboard warning showed only 44 miles left before the truck would be disabled – meaning we had to act fast to keep it in service. Initially, we thought this would be a straightforward job, but it quickly turned into a test of patience and skill: Thankfully, owner Les was patient and understanding as we worked through the process. After hours of careful work, we completed the custom programming, reinstalled both ECUs, and successfully cleared the AdBlue faults. This little Grafter is now back on the road and ready for many more years of reliable service. At Kernowsport, whether it’s a simple remap or a complex multi-ECU job, we go the extra mile to get your vehicle running right.
