Peugeot 208 Adblue Delete and countdown reset

Peugeot 208 AdBlue Delete and Countdown Reset in Praa Sands, Cornwall

We were called out to another AdBlue-related emergency, our fourth one this week—and it was only Monday! Liz, a Peugeot 208 owner from Praa Sands, was understandably stressed. Her vehicle was showing the dreaded AdBlue countdown warning, threatening a no-start in under 300 miles—despite spending over £1,000 in recent weeks trying to resolve the issue. With long drives being part of daily life in Cornwall, we knew how important it was to get Liz back on the road quickly. Thankfully, she was just down the road from us, so we headed straight over. We carried out a complete AdBlue delete and reset the countdown, removing the issue permanently and restoring full peace of mind. We joked about accepting her adorable little dog as payment—but thanks to our mobile card reader and Starlink-powered mobile internet, a quick card payment did the trick! Another happy customer and another AdBlue delete completed—next stop, Leedstown!

Vauxhall Vivaro Stage 1 Remap

Evening Mobile Van Remap for Tradesman in Godolphin – Stage 1 ECU Upgrade to 160BHP Another last-minute job completed today by the Kernowsport team! Tim, a hardworking self-employed tradesman, needed a power boost for his van—but couldn’t afford any downtime during his busy workday. We arranged an evening remap service to suit his schedule. Conveniently, we had just finished a tuning job nearby in Godolphin, so we stopped by on the way back to Kernowsport HQ in Hayle to carry out the upgrade. Tim’s van was running a standard 109BHP engine, which was struggling with hills and overtaking. After a Stage 1 ECU remap, the van is now producing 160BHP—giving it a major performance boost. Tim described the improvement as “a big and noticeable difference!” At Kernowsport, we understand that your van is your livelihood. That’s why we offer mobile ECU remapping across Cornwall, working around your schedule—whether that means evenings, weekends, or while you’re on a job. 👉 Contact us today to book your mobile van remap and experience the Kernowsport difference..

Mercedes E250 WGR delete, DPF delete and remap by Kernowsport

Mercedes E250 Diagnostic & ECU Repair – Mobile Visit to Falmouth

This Mercedes E250 came to us with multiple dashboard warning lights, including check engine, service required, and EGR system faults. The vehicle was in a poor state, but we were more than happy to help — even on a Sunday morning, travelling directly to the customer in Falmouth. As the ECU had already been remapped elsewhere, we started by taking a full backup of the existing file. We then carefully removed the EGR and DPF warning codes, resetting all fault lights and restoring the vehicle to full working order. Now, the dashboard is completely warning-free, and the customer is safely back on the road. Thanks to our Starlink satellite internet, we’re also able to accept secure card payments from any location — making our mobile vehicle diagnostics and ECU tuning services even more convenient across Cornwall.

Adblue No Start Warning removal

Audi A4 Quattro No Start with Adblue

AdBlue Fault? KernowSport Offers Fast Mobile AdBlue Fixes Across Cornwall Living in Cornwall means enjoying stunning scenery—and few views compare to the one we had on this recent job in St Agnes. Our customer had just returned from Dorset, only to wake up to a frustrating “no start” AdBlue fault on their vehicle. At KernowSport, we specialise in resolving AdBlue system issues quickly and efficiently. Whether you’re at home, work, or enjoying a day out in Cornwall, our mobile service comes to you—saving you the hassle of visiting a dealership. When an AdBlue fault warning appears, some vehicles initiate a countdown to “no start,” meaning your car won’t start again until the issue is cleared by a technician. Luckily, our advanced diagnostics and repair technology allow us to reset these faults and get you back on the road fast—without the need for main dealer intervention. And if the view is as beautiful as it is in St Agnes, well, that’s just an added bonus!

Peugeot Partner Adblue Delete

Sunday Morning Adblues!

AdBlue Fault Fixed on Peugeot Partner for Local Fishermen – Weekend Service in Hayle At KernowSport, we understand that many of our customers work unpredictable hours – especially those in demanding jobs like fishing. This recent job involved a Peugeot Partner, owned by fishermen based on the Lizard Peninsula. With their schedules dependent on the weather and tides, flexibility was key. They dropped the vehicle off with us in Hayle on a Saturday, and we had it ready – AdBlue warning light cleared – by Sunday. Quick turnaround, even over the weekend, is just one way we support our hard-working customers across Cornwall. The Peugeot Partner is part of the Stellantis group of vans, and we see these models regularly in our workshop. Many are low mileage, relatively new vans with AdBlue system faults or engine management lights showing. This particular van had just 40,000 miles on the clock, but we’ve worked on similar models with as few as 10,000 miles already experiencing issues. While the long-term reliability of these AdBlue systems remains uncertain, we’ve ensured this van is now running fault-free with no more AdBlue warnings. If you’re dealing with AdBlue problems, engine warning lights, or need a mobile

VW Crafter L4 H2 Emergency AdBlue Fix

Another holiday saved!

Emergency AdBlue Fix and Performance Remap for a VW Crafter Camper – Newquay, Cornwall We received a message at 11:30pm on Saturday night from Steve and his wife, who were travelling from Manchester when their VW Crafter camper van triggered a warning: the AdBlue countdown light had come on while driving along the A30 in Cornwall. As they continued, the range suddenly dropped to just 350 miles remaining. Despite the late hour, we were happy to help. We arranged to meet them at Morrisons in Newquay at 10am Sunday morning to diagnose and fix the AdBlue issue. Their VW Crafter L4 H2 camper conversion was one of the best we’ve seen – originally an ex-delivery van, now a beautifully converted camper in near-pristine condition. While working on the AdBlue problem, we also carried out a custom performance remap to enhance the vehicle’s power and efficiency. We hope Steve and his wife enjoy their stay in Cornwall and have a smooth, trouble-free journey back to Manchester.     Need Help With AdBlue or Camper Van Remapping in Cornwall? If you’re stuck with an AdBlue fault, engine management warning, or want a performance remap for your VW Crafter, Mercedes Sprinter, or any

Performance Upgrade: Fiat Ducato Remap & DPF Regeneration

We recently gave our ex-BT Fiat Ducato a much-needed performance boost. The standard 2.0L 2017 model comes with just 115BHP – the entry-level engine in the Ducato range – and it really shows when climbing hills. It’s a solid van, but a little sluggish, especially when fully loaded. This model, like most Ducato, Boxer, and Relay vans, requires the ECU to be removed for tuning – a bit of a hassle, but it comes with benefits. Removing the ECU allows us to take a full backup of the original software, which is always handy if a rollback is ever needed. While it may look like open-heart surgery for your van, ECU removal on the Ducato is fairly straightforward. And the results speak for themselves: we boosted the power from 115BHP to a lively 190BHP – a transformation you can really feel on the road. We also carried out a DPF regeneration and removed the factory speed limiter, giving the van a much smoother and more responsive drive. If you’ve got a Fiat van that’s feeling underpowered, this is a great reference point for what’s possible. Get in touch to unlock your van’s full potential.

Adblue Delete Seat Alhambra

Come on Holiday, Can’t get home!

This poor customer had driven all the way from Wales to enjoy a well-earned holiday in Cornwall—only to be hit with the dreaded AdBlue countdown on their Seat Alhambra Estate. With a faulty sensor and not enough miles left to get home, their relaxing break suddenly turned stressful. Luckily, they gave Kernowsport a call, and we were more than happy to help. We headed straight out to their holiday site in Hayle and got to work on the spot. To make matters worse, their car was a 2011 model—one of the unlucky few from that year fitted with AdBlue—so this wasn’t a common fault with a quick fix. But no worries—we’ve seen it all before. As always, our trusty Starlink internet connection came to the rescue, allowing us to complete the job even in a no-signal area. We sorted the issue quickly and let them pay by card before sending them on their way—problem solved, holiday saved. Here’s hoping they come back to Cornwall next year—minus the car trouble!

Mercedes Benz A180 AMG 1.5 Diesel Stage One Remap

Mercedes Benz A180 AMG 1.5D Bluetec Remap

This one was a bit of a sleeper—looked fast, but according to its owner, it didn’t quite have the performance to match! With just 109BHP under the bonnet from its small diesel engine, it was crying out for a bit more punch. We were more than happy to help, and headed out on-site to RNAS Culdrose to carry out a remap. We boosted the power up to a much healthier 150BHP, giving the car the performance it should’ve had from the start. Now it drives as good as it looks, and the owner couldn’t be happier with the transformation. Thanks to our fully equipped van—complete with high-speed Starlink internet—we can download vehicle files and software updates from pretty much anywhere. We even take card payments on the spot. Whether it’s a remote airfield or somewhere deep on the Lizard Peninsula, we’ve got it covered.
