VW Transporter T5 at RWG Engineering in Pool, Redruth for ECU remap correction by Kernowsport

VW Transporter Remap & Turbo Issue Fixed in Pool, Redruth

Whilst at RWG Engineering in Pool, Redruth, we were asked to take a look at a heavily modified VW Transporter suffering from a mix of turbo, EGR, DPF, and remap issues. Judging by its colour, we suspect this van may have once had a previous life with a well-known breakdown company! With 249,000 miles already under its belt and now on its third engine, this T5 had clearly had a tough working life. On inspection, we found that the existing remap was far too aggressive, pushing excessive boost. The result? Overboost issues that were so severe they were blowing the welds off the aluminium turbo pipe — something we don’t see every day! To resolve the problem, we carefully backed off the map to make the power delivery smoother and the boost more controlled. This not only improves reliability but should also stop the constant frustration of repairs for the owner. We always enjoy seeing repeat customers, but we’d rather it be for upgrades and improvements, not for fixing unnecessary issues caused by poorly calibrated maps. Why Choose Kernowsport for VW Transporter Tuning? If your VW Transporter has been poorly tuned or is suffering from boost, EGR, or DPF problems,

Land Rover Defender TD5 Remap & EGR Delete in Redruth

One of today’s jobs was a Land Rover Defender TD5 in Redruth that had been suffering from excessive smoke caused by a faulty aftermarket tuning box. The issue meant it was repeatedly failing its MOT emissions test, leaving the owner frustrated. We were happy to head back to our friends at RWG Engineering in Redruth to get this sorted properly. The solution was straightforward: The results spoke for themselves. Despite having over 250,000 miles on the clock and being in daily use as a working vehicle, the Defender is now running smoothly and cleanly — like new again. We love working on Land Rover Defenders. They’re known for their toughness, simplicity, and reliability, even after decades of use. This TD5’s old-school OBD system allowed us to read and write the ECU in under 3 minutes, making the process quick and efficient.

VW Transporter T5 in St Austell with EGR delete by Kernowsport

VW Transporter T5 EGR Delete in St Austell for Holidaymaker

Another VW Transporter T5 and another holidaymaker helped this Sunday morning in St Austell, Cornwall. Jack, visiting from Southampton, was enjoying a few days in Kernow when his much-loved 2004 VW T5 began having EGR issues. Despite having an incredible 311,000 miles on the clock, the van still looked in great condition — more like one with half the mileage. Originally fitted with the 2.5 engine, this T5 produced an impressive 175BHP stock, and after a performance map earlier in its life, it was closer to 220BHP. Jack had already removed the EGR valve himself, but he needed Kernowsport to carry out the ECU EGR delete to finish the job properly. We were more than happy to help and get the van running at its best again. (Although, in true Kernowsport style, we managed to forget our OBD reader and had to make a quick detour to Par to collect it afterwards!) It was great to meet Jack, and we hope he and his Transporter enjoy many more miles of adventures across Cornwall and beyond. Why Choose Kernowsport for VW Transporter ECU Work? If your VW T5 or T6 needs tuning, ECU work, or DPF/EGR solutions, Kernowsport has the tools,

Isuzu D-Max DPF & EGR Repair in Pool at Harts Haulage

Today, we paid a visit to our friends at Harts Haulage in Pool to help one of their drivers who was having DPF and EGR problems on his trusty Isuzu D-Max. We’ve been seeing quite a few Isuzus in the workshop lately, so we know our way around them. While we were there, we also took the opportunity to reset the service lights on Boss man Neil’s VW Amarok — which had the full Kernowsport performance treatment a few months ago. It’s always a pleasure to visit Harts and see their impressive mix of lorries — from modern workhorses to beautifully restored vintage trucks that Neil collects. At Kernowsport, we have the specialist tools, software, and cables to handle almost any vehicle, including HGVs, LCVs, plant machinery, and cars.

2016 Range Rover Evoque with DPF issue parked at Kernowsport Camborne workshop

Emergency DPF Fix on Range Rover Evoque in Breage Saves Holiday Plans

Location: Breage / Camborne / St AgnesVehicle: 2016 Range Rover EvoqueService: DPF Fault Fix – Limp Mode RecoveryCustomer: Holidaymakers from Manchester One of today’s standout jobs was a last-minute DPF rescue for a lovely family from Manchester who were on holiday in St Agnes, Cornwall. Their trip was nearly cut short when their 2016 Range Rover Evoque went into limp mode due to a DPF warning light coming on — a frustrating and stressful problem, especially far from home. Luckily, they were in Breage when the fault occurred, and their route back to St Agnes took them right past our Camborne workshop. After giving us a quick call, we arranged to take the vehicle in right away. We quickly diagnosed the issue and carried out the necessary DPF repairs and remap, getting the Evoque out of limp mode and back on the road in time for them to make their journey home the next day. From St Agnes to Manchester is no small drive, and we were more than happy to help ensure they weren’t stranded. At Kernowsport, we pride ourselves on helping people when they need it most — even if that means taking on emergency jobs outside of

DPF and EGR delete with performance remap on Vauxhall Zafira St Austell

Evening ECU Remap and Emissions Solution for Vauxhall Zafira in St Dennis

One of our jobs today took us to St Dennis, just outside St Austell, to help local customer Liam with his rough-running Vauxhall Zafira. He had booked in for an EGR delete, DPF delete, and a custom performance remap — and as always, Kernowsport was happy to work around his schedule and attend in the evening after he finished work. This particular Zafira posed an extra challenge: unlike many vehicles that allow remapping via the OBD diagnostic port, this one required the ECU to be removed and connected directly via cable. While it may look like open-heart surgery, this method is often safer. It allows us to take a full backup of the ECU and gives the flexibility to return the car to its original factory settings if ever needed. Once connected and mapped, the transformation was huge. The Zafira now produces a healthy 200BHP, offering far better throttle response, smoother power delivery, and a noticeably more engaging drive. Liam was a happy man, and we were glad to bring another vehicle back to life in mid Cornwall. At Kernowsport, we specialise in mobile ECU remapping and diesel tuning across Cornwall – including evening and weekend appointments. Whether you’re in

Ford Transit ice cream van remap and EGR delete in North Country Redruth by Kernowsport

Ford Transit Ice Cream Van and Hyundai Tucson Remapped in Redruth by Kernowsport

Jobs two and three today took us to North Country near Redruth for an interesting pair of vehicles — including our very first ice cream van! The first job was on a 2002 Ford Transit ice cream van fitted with the naturally aspirated 2.4-litre engine. While these older engines don’t offer huge tuning gains, we were still able to increase power from 75bhp to around 115bhp. Alongside the performance bump, we resolved a few engine management issues following an EGR delete, giving this hard-working van a new lease of life. The second job was a more familiar one — a Hyundai Tucson turbo diesel. This vehicle saw a gain of around 40bhp with a custom remap, transforming its acceleration and torque. The improvement in responsiveness was clear on the test drive, and the customer was extremely happy with the results. Most importantly, the ice cream van is now ready to hit the road again, just in time to serve customers at the local car boot sales and community events. At Kernowsport, we love working on all types of vehicles — whether it’s a family SUV or a local business van serving sweet treats to Cornwall’s families. Mobile Remapping in Redruth

VW Transporter T5 remapped at Heron Refurbishing in Camborne by Kernowsport

VW Transporter T5 EGR Delete and Remap in Camborne – 102BHP to 187BHP with Kernowsport

This was the first of five remapping jobs we had booked in for the day, and it started with a last-minute request the evening before from Andy at Heron Refurbishing in Camborne. His Volkswagen Transporter T5 was in need of some serious help, struggling with hill performance when fully loaded — a common issue with the 102bhp models. We were happy to shuffle our schedule to fit him in first thing at his workshop in Troon. The van had just 133,000 miles on the clock and was in great condition, but it needed more power to keep up with the demands of daily commercial use. After carrying out a full diagnostic, we performed an EGR delete and applied a custom stage one performance remap. By the time we left, the van had gone from 102bhp to a much more capable 187bhp — a massive upgrade that Andy immediately felt. The improvement in torque and driveability was clear from the first test drive, especially on hills and when under load. Andy was thrilled, and now the van performs like it should have from the factory. At Kernowsport, we understand that when your van is your livelihood, it needs to be reliable,

Vauxhall Vivaro at RWG Engineering Redruth receiving a Stage One remap by Kernowsport

Vauxhall Vivaro Stage One Remap and Emissions Fix at RWG Engineering, Redruth

We were recently called out to help with a 2018 Vauxhall Vivaro at RWG Engineering in Redruth — and this one had a full list of common van troubles. Like many late-2010s Vivaros and similar Peugeot models, it was suffering from a combination of EGR problems, AdBlue faults, and DPF issues. This hardworking van was clearly tired and running rough, and with it being a vital vehicle for the team at RWG, they needed a fast, professional fix. Owner Ross decided to make the most of the visit by having a stage one performance remap done at the same time — a great way to boost reliability and driveability once the emissions faults were resolved. We carried out the work at the Harts Haulage workshop in Pool, where RWG Engineering is based. At Kernowsport, we understand that vehicles like this are tools of the trade — downtime costs money. That’s why we were happy to get to the site by 6PM to make sure everything was sorted and back on the road by morning. The result? A smoother, stronger, and more reliable Vivaro — with a noticeable boost in performance thanks to the custom remap. Mobile Van Remapping and Diagnostics

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.
