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.

While that sounds daunting, the good

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

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,

We seem to have worked on a lot of BMW 1 Series diesels recently, and this visit to Lanner, near Redruth, was another great example of why they remain such a popular choice for tuning. The owner had already completed the physical DPF and EGR removal himself and called on Kernowsport to take care of the software side, along with a Stage 1 performance remap to bring everything together properly. An Early BMW 1 Series – And One of the Cleanest We’ve Seen This particular car was a 2004 model, making it one of the earliest BMW 1 Series diesels on the road. Despite its age, it was also one of the cleanest examples we’ve seen for the year—clearly well looked after and a real bargain for the owner. With the right tuning and software corrections, cars like this can continue to offer reliable, economical motoring for years to come. Why BMW 2.0D Engines Are Fantastic Value to Tune BMW’s 2.0D diesel engines are among the best “bang for buck” engines we work on here at Kernowsport. Depending on the year and specification, a Stage 1 remap can typically take these engines from: That means: It’s hard to find another

Today’s visit took us to Mount Hawke to help our friends at Lockley Contracting, who had a customer with a Mercedes Vito undergoing a DPF hardware delete. They asked Kernowsport to come in and complete the software corrections and add a reliable performance remap to finish the job properly. The Vito platform is one of the best vans on the market for tuning—smooth to drive, robust, and very responsive to a well-written map. From 114bhp to 130bhp – A Noticeable Boost This Vito began as a 114bhp model, but with some Kernowsport tuning magic, we safely increased it to around 130bhp, giving the owner: At the same time, we corrected the EGR and DPF fault codes that naturally occur following hardware removal. The result?A cleaner-running van, more power underfoot, and a much happier customer.

Today we headed up to Wadebridge to work on another Citroën Relay Luton van for one of our repeat customers. This particular vehicle has truly lived a hard-working life—clocking over 260,000 miles, the equivalent of driving around the world ten times! And impressively, it’s still not the highest-mileage van in their fleet. The owner runs an antique-dealing business and a busy “man and van” service, meaning the van needs to be out on the road 24/7, earning its keep. We had previously tuned another one of their Relays, so they knew exactly who to call when this one needed attention. Fixing a DPF Delete the Right Way This Relay had recently undergone a local DPF delete, but the software side hadn’t been completed properly—resulting in unwanted faults and poor drivability. We were brought in to: Our Blend map is ideal for vehicles like this: It offers a perfect mix of additional power and enhanced fuel efficiency, without the intensity of a full Stage 1 remap—making it a smart, safe choice for hardworking vans.
