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,

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

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 C4 Cactus with AdBlue fault repaired in St Blazey Cornwall by Kernowsport

Citroën C4 Cactus AdBlue Fix in St Blazey Cornwall

Some vehicles seem to suffer with AdBlue problems more than others, and from our experience, the Citroën C4 and DS4 range are among the worst affected. This job in St Blazey was yet another example — our fourth or fifth Citroën AdBlue callout this month alone. The customer’s C4 Cactus had gone into an AdBlue countdown to no start. Occasionally, drivers report that the warning light disappears for a day or two, but unfortunately this is usually temporary. The fault always returns, and when it does, it often becomes permanent. In this case, the owner rang us back two days later with the countdown warning still active and asked us to step in. Thankfully, the C4 Cactus is one of the more straightforward vehicles for us to work on, and we had it up and running again in under an hour. As a bonus, while we were there, we also used our diagnostic equipment to take a quick look at the owner’s BMW X5, helping to narrow down a fault in its body control module. At Kernowsport, if we can help, we always will. Why Citroën & DS Owners in Cornwall Trust Kernowsport Whether you’re in St Blazey, Bodmin, or

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.

VW Crafter camper van driving in Cornwall after AdBlue fix and remap by Kernowsport

VW Crafter Camper AdBlue Fix in Padstow & Hayle

Job number two today was another holiday rescue, this time for a family staying in Padstow with their 2020 VW Crafter camper van. Unfortunately, just as they were preparing to return home to Manchester, the dreaded AdBlue countdown appeared with only 85 miles remaining before no-start mode. That left them unable to risk the long drive home, so they gave us a call. We agreed to squeeze them in last minute on a Saturday afternoon and arranged to meet at McDonald’s in Hayle, where the kids could stay entertained while we got to work. Luckily, we had time to set up before they arrived, and this one turned out to be a quick job, taking less than an hour. While fixing the AdBlue issue, we also applied a stage one performance remap to the Crafter, giving it extra pulling power and smoother performance. By the time we were done, the family were safely back on the road, ready to head home to Manchester without any more AdBlue worries.

Mercedes C-Class back on the road in Cornwall after AdBlue and EGR delete by Kernowsport

Mercedes C-Class AdBlue Delete at St Ives Holiday Park in Hayle

One of today’s jobs took us to St Ives Holiday Park in Hayle, where a Mercedes C-Class diesel was suffering from the dreaded AdBlue countdown. We’ve seen quite a few Mercedes C200 and C220 models recently, all with similar issues. These can sometimes be a little tricky to work with, as the ECUs are either older units that take up to 90 minutes to read, or they need to be removed completely from the car to be remapped. This particular one was simply time-consuming rather than complicated. We carried out a full AdBlue delete, an EGR delete, and also applied a stage one performance remap. The end result? A C-Class that’s back on the road, AdBlue-free, and with improved performance — perfect for both reliability and driving enjoyment. Why Mercedes Owners in Cornwall Choose Kernowsport If your Mercedes diesel is showing AdBlue warnings or countdown messages, don’t wait until it reaches a no-start condition.

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.

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.

Toyota Proace camper in Looe Cornwall with AdBlue fix by Kernowsport

Toyota Proace Camper AdBlue Fix in Looe

Our first job of the day was a trip to Looe to visit Warren, who was having AdBlue issues on his well-kept Toyota Proace camper van. At Kernowsport, we always enjoy working on campervans and conversions — it’s a chance to see the different ways people set them up. Warren’s Proace was a fantastic example, fitted out as a day van with a smart solar system, leisure batteries, and an Apicool fridge. A proper little home-from-home! Unfortunately, like many modern vans, it had started suffering with AdBlue and DPF problems, which can be frustrating and ruin the enjoyment of a trip. Warren decided to call Kernowsport to get it sorted before it spoiled his plans. Luckily, this was one of the quicker jobs for us. We had the AdBlue and DPF issues resolved in under an hour — almost a record! By the time we left, the Proace was back in tip-top condition, ready for many more Cornish adventures.
