Audi TT 2.0 TDI DPF Delete & Performance Remap in Hayle

When you carry out as many Stellantis vans as we do, it can be hard to find something new to say—but that in itself tells the story. This job was a Vauxhall Combo 1.5 diesel in Whitemoor, near St Austell, and it was a textbook example of why these vans make up such a large part of our workload at Kernowsport. Same platform.Same engine.Same ECU.Same AdBlue problem. A Very Familiar AdBlue Fault Like most Vauxhall Combo, Peugeot Partner, Citroën Berlingo and Dispatch models, this van was suffering from: For tradespeople and small businesses across Cornwall, these vans are tools of the trade—and downtime simply isn’t an option. 👉 Learn more about our AdBlue Delete Services and how we help keep working vehicles on the road.

One of Many This Week This Vauxhall Combo wasn’t unusual—but that’s exactly the point. At the time of

This job was number two out of four Stellantis vans in a row suffering from AdBlue problems—and a great example of why experience and proper diagnostics matter. This Citroën Berlingo 1.5D in Newquay was a vehicle we had previously resolved successfully. Unfortunately, after a visit back to the main dealer for an unrelated issue, the dealer performed an ECU software update, which effectively restored the factory AdBlue countdown. Why Dealer Updates Can Undo AdBlue Solutions Modern vehicles store emissions logic entirely in software. When a dealer: …it can overwrite previous modifications, including AdBlue, DPF or EGR solutions. One visit later, we returned to Newquay and reapplied our proven AdBlue solution, fully resolving the issue once again and getting the van back to work without downtime. 👉 Learn more about our AdBlue Delete Services for Citroën, Peugeot and Vauxhall vans. Warning Lights Don’t Always Mean the Same Fault A key point we always explain to customers: ⚠️ Engine and emissions warning lights are not fault-specific A warning light may appear due to: Most modern diesels run three separate emissions systems, each capable of triggering a warning light independently. Seeing a light does not automatically mean the original problem has returned. Professional

Today’s one and only job was a little special—and not just because it took us all the way to Bromley, London. This customer had already tried ten different tuning companies and multiple Isuzu dealers before finally finding Kernowsport. At the time of writing, we—and our calibration partners at Viezu—are confident we are the only company in the UK currently offering a proven AdBlue solution for the Isuzu D-Max Grafter N35. A True Two-ECU AdBlue System The Isuzu Grafter N35 is not a straightforward vehicle. It runs: Both ECUs require bench programming for a complete and reliable solution. When we first tackled this platform, it took nearly two full days of reverse engineering to get the first one working correctly. That investment of time is exactly why we can now resolve these vehicles quickly, safely and repeatably. Specialist Tools, Specialist Knowledge Thanks to specialist leads and tooling, we can now: The mechanical side still takes time—these units are not easy to reach—but what was once a nightmare job can now be turned around in a couple of hours, taking the vehicle from no-start to fully operational. 👉 Learn more about our AdBlue Delete Services. From No-Start to Back in Service This

Number three out of four in this recent run of Stellantis vans brought us deep into the woods near Fowey for an urgent AdBlue countdown issue on this Peugeot Expert 1.6D. Like many of the vans we see, this one wasn’t a weekend toy—it was a working vehicle, and an important one at that. The owner was due to head off on a long work trip to the Orkney Islands, but an AdBlue warning threatened to derail the whole plan. AdBlue Countdown? Don’t Panic One of the most common concerns we hear is panic around AdBlue countdown messages. The good news is: As long as the vehicle is already running, it will continue to run until it’s switched off again—even with an active countdown. This means: That’s exactly what happened here—the owner got the van to us in time, and we were able to resolve the issue quickly and correctly. 👉 For more guidance, see our AdBlue Diagnostics & Delete Services. A Familiar Issue on Stellantis Vans The Peugeot Expert, Citroën Dispatch, Berlingo, Partner and Vauxhall Combo all share common AdBlue and SCR system weaknesses. At this point, many owners see it as an inevitable annoyance rather than a surprise

If it feels like we’re seeing a lot of Citroën Berlingos, Dispatches and other Stellantis vans lately… it’s because we are. This 2017 Citroën Berlingo 1.5D, with over 100,000 miles, was the fourth Stellantis van in just two days—and the sixth this week—all requiring AdBlue system repairs. This one was located deep in the countryside near Landrake, but thanks to careful route planning we had literally just come from another Berlingo near Fowey. Cornwall mileage at its finest. A Common Fault on Stellantis 1.5 Diesel Vans The Berlingo, Dispatch, Partner and Combo vans from this era all share the same underlying platform—and unfortunately, the same AdBlue and SCR system weaknesses. Typical symptoms include: At Kernowsport, we now know these systems inside out. 👉 Learn more on our AdBlue Delete & Diagnostics page. Fast, Safe Bench Programming – No ECU Removal Required These vehicles are bench programming jobs, but thanks to our specialist equipment and custom leads, we no longer need to remove the ECU from the vehicle. Instead, we: Once the ECU work is complete, we perform a full SCR system reset, clear all fault codes, and the vehicle is ready to go. This approach is: 👉 See how we

Occasionally, a vehicle arrives that isn’t quite what it seems—and those are the jobs where experience, process and the right tools really matter. This Hyundai Santa Fe diesel met us in Bodmin, having travelled up from Plymouth, with what initially appeared to be a straightforward AdBlue countdown issue. On the surface, it looked like a routine fix. In reality, it turned into a perfect example of why proper diagnostics are essential. OBD Connection Failure – When Things Don’t Add Up Despite multiple attempts, we were unable to communicate with the ECU via the OBD port, something that immediately raised red flags. When this happens, our next step is always a bench read, allowing us to access the ECU directly. Once removed, the ECU told its own story. It had been marked in pen, a common sign that an ECU has been previously replaced or modified. After discussing this with the owner, they explained the vehicle had: That was only part of the story. The Real Issue – Incorrect ECU Fitted During analysis, we discovered the ECU wasn’t even from a Santa Fe at all, but from a completely different Hyundai model. This explained: Once the correct configuration was identified, the
