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

Peugeot Boxer L4 box van with AdBlue, DPF and EGR faults repaired in Cornwall by Kernowsport

Peugeot Boxer L4 AdBlue, DPF & EGR Fix in Wadebridge Cornwall

Some jobs really surprise us — and this Peugeot Boxer from Wadebridge was definitely one of them. We work on a huge number of vans across Cornwall, particularly the Fiat Ducato, Citroën Relay, Peugeot Boxer, and Vauxhall Movano platforms. Most of them are L2 or L3 wheelbase models, often converted into motorhomes or campers. This one, however, was completely different. At first glance, we almost mistook it for a Ford Transit Luton — but it turned out to be an L4 Boxer with a full box body. An absolute monster of a van, and one of the first we’ve ever seen in this configuration. Fortunately, our Pool workshop near Redruth is fully equipped to handle even the largest vehicles, and this giant just about squeezed in with room to spare. The owner had booked it in with us to resolve a combination of AdBlue, DPF, and EGR issues, which are very common on these vans. Thankfully, the ECU fitted to this one was fairly standard, making it quick and straightforward for us to work with. Within a short time, we had all faults resolved and the van was back to full health, ready to return to work and keep earning

Citroën Berlingo 2020 with AdBlue and DPF fix at Kernowsport Pool Cornwall

Citroën Berlingo AdBlue & DPF Fix for Penzance Customer in Pool Cornwall

Every now and again we come across vehicles that we just don’t enjoy working on — and the Citroën Berlingo with the 1.5 Stellantis engine is one of them! This particular 2020 model, owned by a customer from Penzance, came to us with some serious AdBlue and DPF issues. The owner had already been to the local main dealer, who not only refused to fix the issue under warranty but also quoted over £3,000 for repairs. Understandably, that wasn’t a viable option. Fortunately, they gave us a call at Kernowsport, and we were able to fit them in the same day at our Pool workshop near Redruth. The 2020 Berlingo turned out to have some very peculiar ECU requirements that aren’t typical of most vehicles we work on. Still, with a little time and some persistence, we were able to get it sorted and back on the road without the eye-watering costs of a dealer visit. This is actually the eighth Stellantis-based vehicle (Citroën, Peugeot, or Vauxhall with the 1.5 engine) that we’ve dealt with recently. It’s fair to say they still aren’t growing on us — but we’ll always find a solution for our customers. Why Citroën & Stellantis

2010 Mercedes Sprinter camper van in Pool Cornwall after DPF fix by Kernowsport

Mercedes Sprinter Camper DPF Fix in Pool Cornwall

Mercedes can often be a challenge when it comes to remapping, and this 2010 Mercedes Sprinter camper conversion was no exception. The Delphi ECU is fairly common but also notorious for being temperamental, taking what feels like forever to read and write. This particular Sprinter was stunning inside thanks to a professional camper conversion, but under the bonnet it was a different story. It was regularly throwing EGR and DPF engine management lights, leaving its owner frustrated. Deciding enough was enough, the owner dropped the vehicle off with us in Pool, near Redruth, before heading off camping for the weekend. Our usual Alientech Kess3 tool wouldn’t read this specific ECU, so we turned to our trusty Magic Motorsport Flex, which made quick work of the job and read it in record time. This is exactly why we invest heavily in a wide range of professional-grade tuning equipment. Where one tool won’t work, another will — ensuring we can provide a solution for almost every vehicle we see. With the DPF issues resolved, this Sprinter is now ready to hit the road again, giving its owner peace of mind and a trouble-free start to the next adventure. Why Choose Kernowsport for

Mercedes C220 in Bodmin Cornwall after remap and AdBlue delete by Kernowsport

Mercedes C220 AdBlue Delete & Remap in Bodmin Cornwall

Our final job of the day took us to Bodmin, where we were called out to work on a Mercedes C220. This car had already had a DPF delete and EGR delete, and the owner wanted us to complete the package with an AdBlue delete and a stage one performance remap. These particular C220s can’t be tuned through the usual OBD port, but luckily the ECU is very accessible. Simply removing the plastic engine cover reveals enough space to connect directly without even having to remove the ECU from the car. The bonus of this approach is speed — while an OBD read can take up to 90 minutes, a direct ECU connection takes less than five minutes. It’s actually the quickest and safest way to remap this model. With the job complete, the Mercedes C220 left Bodmin with a permanent AdBlue solution, more power, and improved drivability. Another successful job ticked off, and then straight on to the next one! Why Mercedes Owners Choose Kernowsport in Cornwall If you own a Mercedes C-Class, E-Class, or Sprinter, Kernowsport can deliver reliable AdBlue fixes and performance remapping across Cornwall.

DPF cleaning and removal on Audi Q3 at Padsfab Fabrications in Pool Cornwall

Audi Q3 DPF Fix in Pool, Redruth

The first job after the bank holiday took us to our good friends at Padsfab Fabrications in Pool, where we were asked to help with a DPF problem on an Audi Q3. This Q3 had been sat unused for a long time and was suffering from DPF issues, alongside a long list of other faults that needed attention. That’s where our partnership with Padsfab comes in. Ben and the team there are able to deep clean or completely remove DPF systems, something that’s often far more effective than the “squirt-in cleaner” solutions that rarely solve the problem. In fact, DPF deep cleaning and removal has been one of our most popular services recently – we carried out seven DPF jobs in the last week alone. With the Audi’s DPF system sorted, it’s now back on the road and ready to serve as a reliable daily car once again. Another happy customer, and another example of how Kernowsport and Padsfab work together to keep Cornwall’s vehicles running smoothly. Why Choose Kernowsport for DPF Fixes in Cornwall? If your Audi Q3 or any other vehicle is showing DPF warnings, don’t waste time with ineffective quick fixes – let Kernowsport handle it properly.

DPF and ECU diagnostic work on Vauxhall Vivaro by Kernowsport Cornwall

Vauxhall Vivaro DPF Fix in St Ives Cornwall

The last job of the day took us to St Ives, where a hardworking Vauxhall Vivaro was struggling with a blocked DPF. These vans are always interesting to work on, as many of the parts are actually Renault branded – the Vivaro shares a lot in common with the Renault Trafic. When we attempted to read the ECU in the vehicle, it wasn’t possible, so we had to remove it and work on it externally. This method, known as benching the ECU, can look more serious than it is – but in reality, it’s actually the safest way to work. By benching, we can take a complete backup of the ECU before applying changes, meaning there’s always a safety net. Fortunately, in our years of work, we’ve never had to use one of those backups – but we like to know it’s there! With the ECU work complete and the DPF issue resolved, this trusty Vivaro is now back on the road and ready for more years of service. Another happy Kernowsport customer in West Cornwall. Why Kernowsport for DPF Problems in Cornwall? If your van is showing DPF warnings or blocked filter problems, we’ll get you back on the

Jaguar E-Pace with DPF issues fixed by Kernowsport in Pool Cornwall”

Jaguar E-Pace DPF Fix in Hayle & Pool

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!

Peugeot 308 in Gorran Cornwall fixed by Kernowsport after AdBlue and DPF issues

Peugeot 308 AdBlue & DPF Issues Resolved in Gorran

On our way home from Looe, we received a call from the lovely Lisa about the second AdBlue problem of the day. Her Peugeot 308 was not only showing AdBlue warnings, but also flashing up a DPF cleaning required message — a double headache no driver wants to see. Lisa lived in Gorran, which (luckily for her, less so for our travel time!) was on our way back to Hayle, so we were happy to stop by and help. When we plugged in our Autel professional diagnostic tool, the ECU revealed more than 30 fault codes — far from normal. After a bit of investigation, we discovered the culprit: a broken battery connector that was intermittently cutting power and confusing the system. Once repaired, we carried out some ECU work, AdBlue adjustments, and a full code reset. By the end, Lisa’s Peugeot was running smoothly again, with no more limp mode or warning lights. At Kernowsport, we know how stressful AdBlue and DPF problems can be, especially when they threaten to leave you stranded. That’s why we offer fast, mobile solutions across Cornwall.

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,

Fiat Fiorino delivery van in Cornwall running smoothly after DPF solution

Fiat Fiorino DPF Delete in Pool near Redruth

Today we were in Pool near Redruth carrying out two DPF delete jobs, one of which was on this Fiat Fiorino owned by Jemima, a hardworking delivery driver. Like many delivery vehicles, her Fiorino was constantly doing short journeys and idling for long periods — the perfect recipe for DPF blockages. In fact, Jemima told us that her last diagnostic reading showed the DPF was an incredible 300% full! We couldn’t help but laugh at her sense of humour, with a sticker on the back of the van that read: “Sorry I am in limp mode.” Using our advanced diagnostic tools, we were able to reset the DPF and carry out a permanent DPF delete, ensuring Jemima could get back on the road without the risk of limp mode slowing her down again. Now she can continue making her deliveries across Cornwall with peace of mind, and we’re confident she has thousands of trouble-free miles ahead. Why Choose Kernowsport for DPF Solutions in Cornwall? If you’re struggling with DPF issues on your car, van, or fleet, give Kernowsport a call. We’ll get you back on the road quickly and reliably.

Maserati Ghibli at Pasfab in Pool Cornwall for DPF delete and performance tuning by Kernowsport

Maserati Ghibli DPF Delete & Performance Tune in Pool

This Saturday morning, we were over at Pasfab in Pool carrying out a few DPF deletes — and the first job of the day was something a little special. Rachel brought in her Maserati Ghibli, which was showing a 100% full DPF warning. Left untreated, a blocked DPF can cause serious running problems, but we were able to put things right with our expert DPF delete service. While we were fixing the issue, Rachel’s partner — a self-confessed petrolhead — decided to go one step further. We carried out a performance remap on the Maserati, pushing its power up to around 350BHP. Not bad at all for a big four-door luxury saloon! We didn’t get the chance to take this Italian beauty for a test drive ourselves, but there’s no doubt it now runs like a rocket — and with its DPF issues firmly behind it, Rachel can enjoy the drive without worry. At Kernowsport, we offer a full range of DPF delete and cleaning services alongside performance tuning packages to make sure your car not only runs reliably but performs at its very best.
