ABS sensor diagnosis and repair on VW Sharan in Cornwall

VW Sharan AdBlue Fix and ABS Diagnosis in Carnon Downs

At Kernowsport, we often help visitors to Cornwall get back on the road quickly when unexpected vehicle issues strike during their holiday. This recent job involved a VW Sharan 2.0 TDI staying at Carnon Downs Holiday Park, where the owner, Jo, had been struggling with persistent AdBlue system faults. Diagnosing the AdBlue System Fault Jo had first contacted us back in July after multiple failed attempts elsewhere to resolve her AdBlue issue. By the time we arrived, the Sharan’s dashboard was showing the dreaded “No Start in 100 miles” countdown — something no driver wants to see while away from home. Fortunately, we were finishing up another job in Porthtowan, so it was just a short trip over to Carnon Downs. Once there, our diagnostic tools confirmed that the AdBlue system had a fault that could be corrected on-site. 👉 Learn more about how we fix these systems on our AdBlue Delete and Repair page. Uncovering an ABS Sensor Problem While working through the diagnostics, we noticed that the Sharan had multiple warning lights on the dashboard. Jo suspected they were all related to the AdBlue issue, but further investigation revealed a faulty ABS sensor as a separate problem. This

VW Caddy Maxi in Carharrack at Kernowsport workshop for DPF and AdBlue fix

VW Caddy AdBlue & DPF Fix with Performance Remap in Carharrack

At Kernowsport, we’ve worked on countless VW Caddys, and we never get tired of them. They’re practical, reliable, and always respond well to a tune. This particular job was in Carharrack, where we looked at an ex-British Gas VW Caddy Maxi M44 2.0 TDI that was suffering from AdBlue and DPF issues. Diagnosing the DPF Problem DPF problems can be some of the most frustrating issues for vehicle owners. A blocked DPF doesn’t just cause reduced performance — it also creates backpressure that can lead to multiple fault codes, warning lights, and other knock-on engine issues. In this case, our diagnostic equipment showed the DPF soot reading was at around 50% of its lifespan. That meant a DPF clean would be effective, restoring the filter without the need for costly replacement. After the usual plumes of smoke during cleaning, the Caddy was back to driving like new, with smooth power delivery and no backpressure issues. Stage 1 Remap for Better Performance The owner also decided to take the opportunity to carry out a Stage 1 ECU remap. With the extra weight the van regularly carried, a performance tune made perfect sense. The result? Noticeable improvements in power, torque, and drivability,

Ford Ranger back on the road in St Ives after Kernowsport DPF fix

Ford Ranger DPF Clean & Diagnostics in St Ives

We’ve worked on plenty of Ford Rangers at Kernowsport, from the rugged diesel workhorses to the high-performance Ford Ranger Raptor. This particular Ranger from St Ives was a real head-turner, finished in a stunning colour — but unfortunately, it had a blocked DPF along with a few other fault codes. After a dramatic start where it smoked like a train, our DPF cleaning service did its job. Within a couple of minutes, visibility was back to normal and the Ranger was pulling like a train once again. Specialist Diagnostics for Ford Rangers Alongside the DPF fix, the Ranger had several TPMS warnings, which required our specialist diagnostic tools to reset and relearn the system. Using advanced equipment such as Forscan and VCDS, we were also able to track down one final sensor issue and provide a full solution. This is a great example of how Kernowsport goes beyond standard ECU remapping. Our investment in specialist diagnostic tools means we can carry out manufacturer-specific functions, helping us keep vehicles like this Ranger running at their best. Why Ford Rangers Benefit from Kernowsport Expertise The Ford Ranger is one of the most popular pickups in Cornwall, used for everything from commercial work

VW Caddy Mk3 1.6 TDI remap and EGR delete in Camborne by Kernowsport

VW Caddy Mk3 EGR Fix & Remap in Camborne

Our first job on Saturday morning took us back to Camborne, where we worked on a VW Caddy Mk3 1.6 TDI. This van was experiencing the all-too-common EGR issues, and the owner also wanted to take the opportunity to add a performance remap. By applying our EGR delete service and performance tuning, we were able to safely push the little 1.6 TDI engine to its maximum of 150BHP — a huge improvement in both power and drivability. Why We Love VW Caddys At Kernowsport, we’ve worked on plenty of Caddy Mk4s and Caddy 2Ks, but this was the first Mk3 we’ve seen in quite a while. We’ve always had a soft spot for the VW Caddy range – they’re reliable, versatile, and respond really well to ECU remapping. The owner was thrilled with the results, and we had a great chat about his other car — a 1998 Ford Fiesta, which brought back plenty of memories as it was the same year we bought one new ourselves. Proof that time flies! A Strong Result for a Small Engine This job was a perfect example of how even smaller engines can benefit from performance remaps. With the EGR issues resolved and

Isuzu Rodeo enjoying improved power on Cornish roads after remap

Isuzu Rodeo Remap in Carnhell Green – More Power for a Cornish Workhorse

On the way back from Falmouth to Hayle, we stopped in Carnhell Green to carry out a quick but rewarding job on an Isuzu Rodeo. The owner wanted a little more power and torque from his workhorse – and just enough of a boost to make sure it was quicker than his partner’s VW! Performance Remap Results The Isuzu Rodeo left the factory with 138BHP, but thanks to our performance remapping service we were able to deliver a much more lively drive. The difference was described by the owner as “really noticeable” — exactly the kind of feedback we love to hear. While raw BHP figures don’t always tell the whole story, what really matters is: Every driver has different expectations, but in our experience, turbo diesels offer some of the best gains when tuned correctly. Neighbourhood Interest in Performance Tuning One of our favourite things about these jobs is that when neighbours see and hear the improvements, they often want the same for their own vehicles. Word of mouth and real-world results are the best adverts for what we do here at Kernowsport. 👉 Considering a remap for your car, van, or pickup? Check out our Stage 1 remapping

Kernowsport roadside ECU diagnostics on Vauxhall Insignia in Hayle

Fast Vauxhall Insignia EGR Fix in Hayle – Kernowsport to the Rescue

Saturday jobs can often be unexpected, but this one was particularly local. A father driving his son to Paradise Park in Hayle suddenly noticed the EGR engine management light appear on the dash of his Vauxhall Insignia diesel. With the risk of the vehicle going into limp mode, he needed a quick fix before the day out could continue. Fortunately, Kernowsport is based nearby in Hayle, and we were able to get to the customer in less than five minutes.

Ford Raptor ECU remap in Wadebridge Cornwall by Kernowsport

Ford Raptor Remap in Wadebridge – Kernowsport Leads the Way

After completing a Land Rover Freelander remap in Wadebridge, Simon asked us to look at his Ford Raptor for a performance upgrade. Several other tuners had already turned him down, saying it couldn’t be done. But at Kernowsport, we pride ourselves on having the specialist tools and expertise to take on jobs that others can’t. The First Ford Raptor Remap of Its Kind Thanks to our Magic Motorsport Flex tool, we were able to access the Raptor’s ECU where others had failed. This wasn’t a straightforward process — nobody in the UK had remapped this particular model before, so we had to have a custom file written specifically for it. The result? Close to 400BHP unleashed from this mighty truck. 👉 Learn more about our approach to ECU remapping in Cornwall. A Beast on Cornish Roads Once the work was complete, Simon took his Raptor out for a drive and was blown away by the results. Despite its size and weight, the remapped Raptor now pulls like a missile — combining brute power with smooth delivery. At Kernowsport, that’s exactly what we aim for: performance you can feel, tailored to the individual vehicle. Why Choose Kernowsport for Performance Tuning? 👉

Kernowsport mobile ECU remapping service in Wadebridge Cornwall

Land Rover Freelander Remap in Wadebridge

At Kernowsport, it often works out that one job leads to another. After finishing a job in Wadebridge, we received a call from Simon asking us to look at two vehicles — a Land Rover Freelander and a new Ford Raptor. Naturally, the Raptor was tempting, but the first task of the day was to remap the Freelander, which belonged to his daughter. Freelander Remap: A Trusted Upgrade This particular Freelander was a 2004 model running the trusty TD4 diesel engine. While older engines don’t always produce the dramatic gains of modern turbocharged units, we were still able to achieve a performance increase of around 40bhp. That extra power means: 👉 For more details on how we transform vehicles across Cornwall, visit our ECU Remapping page.

Nissan Navara prepared for European road trip after AdBlue solution in Wadebridge Cornwall

Nissan Navara AdBlue Fix in Wadebridge

At Kernowsport, we’re no strangers to helping drivers keep their adventures on track. Recently, we received a call from Lisa, whose Nissan Navara had developed an AdBlue countdown fault while staying at a campsite near Wadebridge. Lisa and her partner were preparing for an incredible road trip across Europe, with plans to tour through Romania — but their Navara wasn’t going to get very far with the countdown threatening to disable the vehicle. AdBlue Fix for the Nissan Navara The morning we arrived, Cornwall treated us to a crisp, cold start. The countryside setting of their campsite was stunning, but the Navara needed attention before the journey could continue. Luckily, this particular Navara was one of the more straightforward AdBlue delete jobs. Within a short time, we had resolved the issue and ensured the vehicle was running reliably again. 👉 If you’re experiencing similar issues, our AdBlue delete service covers everything from Nissan 4x4s to Mercedes cars and even commercial vans.

Mini Clubman Cooper S catalytic converter clean and remap at Kernowsport Pool Cornwall

Mini Clubman Cooper S Remap & Catalytic Converter Clean in Pool

At Kernowsport, we often see cars arrive that need a bit of preparation before any performance upgrades can be applied. This Mini Clubman Cooper S at our Pool workshop was a perfect example. The owner had already fitted a larger aftermarket turbo, but the car was suffering badly with a blocked catalytic converter. With the exhaust system choked, the turbo and engine were never going to perform at their best. Catalytic Converter Clean in Pool The first job was to carry out a full catalytic converter clean. A blocked cat not only restricts power but can also cause long-term engine damage if ignored. Once this was resolved, we moved on to the performance tuning. 👉 If your car feels sluggish or keeps showing fault codes, our diagnostics service can quickly find the cause, whether it’s a DPF issue, blocked catalytic converter or other fault. Stage 1 Remap for More Power With the airflow sorted, we installed a Stage 1 performance remap to take full advantage of the upgraded turbo. The results were impressive, delivering significant extra power. The owner took it for a drive and was blown away by the difference — but unfortunately, so was the Mini. On the

Kernowsport diagnostics on Mini with flat battery and ECU fault in Hayle Cornwall

A Busy Day of Car Diagnostics & Remapping in Hayle, Penryn & Pool

At Kernowsport, no two days are ever the same. Today’s work took us across Hayle, Penryn and Pool, covering a variety of jobs that kept us on our toes. Mini Diagnostics in Hayle The first callout was close to home in Hayle, where a little Mini was suffering from a flat battery and a faulty control unit. A quick diagnosis confirmed the problem, and we were able to advise the owner on the most cost-effective repair to get them back on the road. If you’re in Hayle or nearby and need vehicle diagnostics, we’re fully equipped with advanced tools to track down faults quickly and accurately. Immobiliser Issue for a Local Joinery in Penryn Next, we headed to Penryn, where a local joinery business — who also help us with ply lining and carpeting — were experiencing issues with their van. The culprit turned out to be a faulty immobiliser ring in the steering column, a frustrating but common fault on some vans. At Kernowsport, we know how vital vans are to local businesses, so we always prioritise fast roadside or on-site support to minimise downtime.

Audi TT Stage 1 remap in Penzance by Kernowsport

Audi TT Stage 1 Remap in Penzance – 197bhp to Nearly 260bhp

Sometimes the jobs just keep coming, and even on a Saturday afternoon, Kernowsport were called out to Long Rock, near Penzance for a Stage 1 performance remap on a 2009 Audi TT 2.0 TFSI. Unlike many of our jobs, this one was carried out right on the street outside a garage. Passers-by must have thought we were working on one of their cars — but this was all about giving an Audi TT a serious boost in performance. The TT left the factory with 197bhp, but after our remap, it was pushing just under 260bhp. That’s a gain well worth having, particularly in a sporty coupe designed for spirited driving. When the owner took it for a spin, the feedback was exactly what we like to hear: “It feels a lot quicker but also smoother.” This is typical of a Kernowsport remap — not only do we increase power, but we optimise how that power is delivered, improving drivability as well as outright performance. Why Audi Owners Choose Kernowsport 🚗 Book Your Audi Remap in Cornwall Whether you own an Audi TT, A3, A4 or Q5, Kernowsport can help unlock more power, torque, and drivability. 👉 Explore our services: 📞
