Kernowsport Diagnostics & Tuning – Viezu-Approved Mobile ECU Remapping Services in Hayle, Cornwall

The first of three jobs today was this stunning Jaguar E-Pace, the very first one we’ve had the pleasure of working on. Owned by a customer from Hayle – our home town – the E-Pace had been suffering from some DPF (Diesel Particulate Filter) issues that needed urgent attention.

To get the job sorted, we headed over to our friends at Pads Fab in Pool, a workshop we collaborate with a couple of times a week. Pads Fab is run by Ben, a real expert in welding and fabrication, and we’d happily recommend him if you ever need custom work done. He’s one of those rare people who can make almost anything from metal!

With the Jaguar plugged into our diagnostic tools and some ECU work completed, we were able to get the DPF problem resolved quickly, getting the E-Pace running smoothly again. It’s always a pleasure working on something different, and we’re sure this one will now give its owner many more trouble-free miles around Cornwall.

See you in a few days, Ben, for the next one!

Kernowsport carrying out AdBlue delete on Range Rover Evoque.

Range Rover Evoque 2.0d AdBlue Delete – Penzance, Cornwall

Our first job of the day took us down to Alverton, Penzance, to carry out an AdBlue delete on this 2017 Range Rover Evoque 2.0 diesel—a vehicle we’re becoming increasingly familiar with at Kernowsport. We’ve now completed numerous Evoque AdBlue solutions, and an interesting pattern has emerged. Most of the vehicles we see fall into the 2016–2017 model years, suggesting either early teething issues with emissions technology or simply that these systems are now reaching the age where failures become common. A Common AdBlue Problem on Evoques AdBlue faults on these vehicles typically result in: Rather than replacing expensive AdBlue components, many owners choose a software-based solution, allowing them to keep their vehicle on the road without ongoing issues. You can read more about our approach on the AdBlue Solutions page. OBD Programming with Voltage Support From a technical standpoint, these Evoques are a straightforward OBD programming job, with relatively quick read and write times. However, one consistent issue we see is a weak factory battery, which can cause voltage drop during ECU programming. To ensure a safe and reliable write, we always connect a battery conditioner, maintaining stable voltage throughout the process—something that’s essential when working on modern Land

Ford Transit camper after blend remap by Kernowsport.

Ford Transit 2.0 Diesel Camper Remap – Hayle, Cornwall

This local job kept us close to home in Hayle, working on a Ford Transit high-top camper fitted with the 2.0 litre diesel engine—and yes, the much-discussed wet belt variant. The good news?This particular Transit had covered just 44,000 miles and had been meticulously maintained, with no mechanical issues to report. The only thing holding it back was a factory speed limiter, which the owner was keen to remove. Choosing the Right Remap for a Camper Van Rather than going straight for maximum power, the owner opted for our Blend remap option. This is a popular choice for camper and leisure vehicles, as it offers: While Ford Transits can easily exceed 200 bhp with a full stage one remap, this camper was tuned to around 150 bhp, perfectly matched to its usage and long-term reliability goals. You can learn more about our tuning options on the ECU Remapping page. Future-Proofed for More Power One of the advantages of working with Kernowsport is flexibility. Should the owner ever want more performance in the future, this Transit has plenty in reserve: While we often recommend stage one tuning, we recognise that every customer has different priorities—from economy-focused campers to fully loaded work

Vauxhall Corsa 1.2 diesel at Lockley Contracting in Mount Hawke.”

Vauxhall Corsa 1.3 Diesel DPF Delete – Mount Hawke, Porthtowan

Another productive day working with our trade partners at Lockley Contracting in Mount Hawke, just outside Porthtowan. We regularly support independent garages across Cornwall, providing reliable ECU software solutions they can trust—and this job was a perfect example. Blocked DPF on a Vauxhall Corsa 1.3 Diesel Their customer’s Vauxhall Corsa 1.3 diesel had a blocked DPF, causing drivability issues and warning lights. As is often the case, the physical side of the work was handled by Tom and Ollie at Lockley Contracting, who then called Kernowsport in to take care of the software side of the DPF delete. Where appropriate, we also: Because the pricing is the same, most customers choose to take advantage of the performance and reliability benefits while we’re there. Clear, Simple Pricing – No Surprises One thing that sets Kernowsport apart is our straightforward ECU pricing structure. Unlike many tuning companies, we’re happy to: It’s a win-win: improved reliability, better driveability, and more value for the vehicle owner.

Alfa Romeo Stelvio 2.0 Turbo parked in Wendron near Helston.

Alfa Romeo Stelvio 2.0 Turbo Remap – Wendron, Helston

Today’s job took us right into the heart of rural Cornwall, out to Wendron near Helston—one of those locations where mobile tuning really comes into its own. We don’t see many Alfa Romeos here in Cornwall, but the owner of this 2019 Alfa Romeo Stelvio was a lifelong Alfa enthusiast and had owned several over the years. When you meet owners like this, you know the car matters. A Serious Performance Upgrade This Stelvio was the 2.0 Turbo petrol model, producing an already respectable 197bhp from the factory. However, once we’d completed the remap, the final figures were nothing short of impressive: For a 2.0-litre petrol engine in a mid-size SUV, that level of performance is genuinely remarkable. Bench ECU Remapping – The Right Tool for the Job Unlike many vehicles we work on, this Stelvio cannot be accessed via the OBD port due to a factory security module. In these cases, the correct and safest approach is a bench remap. That involves: Fortunately, Alfa Romeo made the ECU easy to access, so aside from the Cornish rain, this was a straightforward and controlled job.

2010 Honda Accord 2.0 diesel in Carharrack near Lanner.

Honda Accord 2.0 Diesel ECU Diagnostic – Carharrack, Lanner

This last-minute call-out took us to Carharrack near Lanner to diagnose a 2010 Honda Accord 2.0 Diesel that wasn’t behaving as it should. The owner reported that the vehicle had previously been remapped and was now suffering clutch slip in the higher gears—a classic symptom that can point to either poor calibration or an underlying mechanical issue. ECU Bench Read for Accurate Diagnosis Normally, if a customer wants a remap adjustment or software update, we would work via the OBD port. However, to properly assess what had been done in the past, this Accord required a full ECU bench read. A bench read allows us to: We sent the file to our trusted calibration partners at Viezu for analysis. The Real Cause: Mechanical, Not Software Interestingly, the existing remap itself was not badly written. However, the data clearly showed that: This is an important point—and one we’re always upfront about at Kernowsport. Software cannot fix worn mechanical components; it can only mask the symptoms temporarily. A Sensible, Honest Solution Rather than pushing more power or attempting to hide the issue, we: This bought the owner valuable time—allowing them to continue using the car while planning and budgeting for a clutch

2019 Peugeot Partner 2.0D showing AdBlue countdown warning.

Peugeot Partner 2.0D AdBlue Delete – Illogan, Redruth

This 2019 Peugeot Partner 2.0D, worked on in Illogan near Redruth, is a textbook example of the AdBlue issues we see week in, week out at Kernowsport. The van arrived with the familiar AdBlue countdown warning and the looming threat of a no-start condition—a situation that quickly turns from an inconvenience into a serious problem when the vehicle is needed for work. Why Peugeot Partner AdBlue Systems Fail Unfortunately, local main dealers are often reluctant to help with these faults and will usually recommend replacing major components such as: It’s not uncommon for quotes to land in the £2,000–£3,000 range, with no real guarantee the issue won’t return. The reality is that AdBlue is an unpleasant, corrosive substance that crystallises easily. Once it starts to build up around sensors and injectors, repeated failures are almost inevitable. The Stellantis platform (Peugeot, Citroën, Vauxhall) is particularly prone to this, and most will suffer problems at some point in their life. A Proven AdBlue Solution from Kernowsport The good news is that Kernowsport has the experience, specialist tools, and software knowledge to resolve these issues quickly and reliably. In this case, we were able to: Most of the vehicles we see like this

Isuzu Grafter N35 engine ECU removal under cab.

Isuzu Grafter N35 AdBlue Delete – A Kernowsport First

At Kernowsport, we’re often asked to work on vehicles that other tuners simply won’t touch—and the Isuzu Grafter N35 is a perfect example. We were proud to be one of the first specialists in the UK to successfully carry out an AdBlue delete on the Grafter N35 LCV, and it’s fair to say this platform did not give up its secrets easily. Why the Isuzu Grafter N35 Is So Challenging Unlike most light commercial vehicles, the Grafter N35 runs two separate ECUs: Both units must be modified for a successful AdBlue solution—and crucially, both ECUs must be physically removed from the vehicle. The engine ECU is particularly awkward, buried deep beneath the cab and secured with security bolts, making access time-consuming.The AdBlue ECU isn’t quite as bad, but Isuzu didn’t make life easy there either, protecting it with a steel anti-tamper plate. The very first Grafter we completed took nearly two full days, as we had to reverse-engineer the system and develop a reliable solution from scratch. Vehicle Off the Road for a Month This particular Grafter had been off the road for over a month, completely unable to start due to AdBlue system faults. For a working vehicle, especially

Citroën Berlingo 1.6 diesel with AdBlue countdown in Perranwell Station.

Citroën Berlingo AdBlue Delete – Perranwell Station, Cornwall

The first job this Saturday morning took us to Perranwell Station near Penryn, working on a 2019 Citroën Berlingo 1.6 diesel that had developed the all-too-familiar AdBlue countdown. Jobs like this are very much bread and butter for Kernowsport. We typically carry out several AdBlue solutions each week on Berlingos, Vivaros, Experts, and related Stellantis models—most commonly with the 1.5 diesel, although this example was the earlier 1.6 variant. Specialist Tools for Faster AdBlue Repairs Because these vehicles are so common, we’ve invested in specialist ECU leads that allow us to connect directly to the ECU under the bonnet, without removing it from the vehicle. This significantly reduces labour time and means we can complete the job cleanly, safely, and efficiently on site, whether that’s at home, work, or roadside. It’s one of the many reasons customers across Cornwall choose Kernowsport for mobile ECU and AdBlue solutions. Why the Berlingo Takes a Little Patience The Citroën Berlingo has one small quirk that makes it slightly more frustrating than some other models:it’s fitted with an immobiliser delay. After writing the ECU, we must wait a full 20 minutes before the AdBlue system can be reset and the vehicle restarted. If the

Audi A3 1.6 TDI in Lanner near Redruth awaiting EGR delete.

Audi A3 1.6 TDI EGR Delete – Lanner, Near Redruth

This job was the second of three vehicles we attended in one day, a good example of how flexible our mobile service can be. We regularly work Saturdays, and with file processing available until early evening, we’re often able to fit in multiple jobs—especially during the longer summer days. £680 EGR Replacement vs Software Solution The owner of this Audi A3 1.6 TDI in Lanner, near Redruth, contacted us after being quoted £680 for a replacement EGR valve. Like many customers, he was unsure whether to replace the faulty component or explore a software-based solution. Once the options were explained, it became a straightforward decision. Rather than replacing an expensive part that is well known for failing again, we carried out a professional EGR delete in the ECU, permanently resolving the issue. Why EGR Deletes Are So Common on VW & Audi Diesels EGR faults are something we see every week, particularly on VW and Audi diesel engines. Over time, carbon buildup and mechanical wear cause: In most cases, a software EGR delete is all that’s required. Once mapped out, the EGR valve defaults to a closed position, and the ECU no longer attempts to operate it. The result is

Ford Mondeo diesel parked in Padstow North Cornwall for DPF delete.

Ford Mondeo DPF Delete & Remap – Padstow, North Cornwall

This job took us up to Padstow on the North Coast of Cornwall and was a little more unusual than most of the DPF work we carry out. A local mechanic had correctly diagnosed DPF issues on this 2010 Ford Mondeo diesel and suggested a DPF delete as the most cost-effective long-term solution. The owner contacted Kernowsport to take care of the ECU software side of the work. Software-Only DPF Deletes – Honest Advice Matters What made this job slightly different is that the owner initially opted for a software-only DPF delete, without physically removing the diesel particulate filter. Typically, a proper DPF delete involves two key stages: While we were perfectly happy to carry out the software work, we clearly explained that leaving the DPF physically in place would eventually lead to blockage, as exhaust soot would still accumulate over time. At Kernowsport, we don’t tell customers what they must do. Instead, we provide clear, honest information, allowing you to make an informed decision based on your budget, usage, and plans for the vehicle. You’re the customer, after all. DPF Delete Completed & Mondeo Back on Form After discussing the options, the DPF was fully removed, and we carried

Audi A5 2.0 TDI in black at Smiley Pistons workshop in Cornwall.

Audi A5 2.0 TDI DPF, EGR Delete & Stage 1 Remap

Today’s first job saw us working on this excellent Audi A5 2.0 TDI, originally from Mousehole, which was booked in at our partner garage Smiley Pistons for a DPF and EGR delete, along with a Stage 1 performance remap. Smiley Pistons certainly attract Audi owners, and over the past few months we’ve completed multiple Audi A5 remaps through their workshop—always a pleasure to work on such well-engineered cars. Low-Mileage Audi A5 in Excellent Condition This particular A5 was a low-mileage example, finished in classic black and in superb condition throughout. Vehicles like this are ideal candidates for software optimisation, especially when emissions-related issues start to appear. DPF faults are common on the Audi 2.0 TDI, particularly on vehicles that see short journeys or mixed driving. Rather than repeatedly repairing components, many owners choose a DPF and EGR software solution, paired with a performance upgrade to enhance drivability. Performance Gains & Safe ECU Programming As expected, the Audi responded very well to tuning, with the 2.0 TDI engine typically achieving around 200 BHP, depending on variant and factory output. Alongside improved power, owners also notice stronger mid-range torque and smoother power delivery. This A5 was completed via a secure OBD connection,

Peugeot Boxer L1 H1 van in Camborne with AdBlue countdown warning.

Peugeot Boxer AdBlue Solution in Camborne

This job took place on a blustery Thursday in Camborne, just ahead of an incoming storm—making for a wet and windy working environment, but nothing out of the ordinary for mobile tuning in Cornwall. The vehicle in question was an unusual L1 H1 Peugeot Boxer, fitted with the 2.0D EcoBlue engine and, unsurprisingly, suffering from an AdBlue countdown warning. With work to do and downtime not an option, the owner needed the issue resolved quickly and reliably. Fast, On-Site AdBlue Resolution We were able to drop in on the way back to Hayle, fitting the job in without disruption to the customer’s schedule. Thanks to our professional tooling, this was a straightforward OBD programming job, completed in around one hour. The work carried out included:✔ AdBlue system reset and software correction✔ Removal of countdown and no-start risk✔ Stage 1 performance remap for improved drivability The additional performance upgrade gives these vans better low-end torque, making daily work and motorway driving far more comfortable. Keeping Working Vans Working At Kernowsport, we understand that a van off the road means lost income. That’s why we prioritise fast response times, mobile service, and reliable results, especially for trades and commercial customers. This Peugeot
