Peugeot 508 AdBlue delete in Hayle Cornwall by Kernowsport

Peugeot 508 AdBlue Delete in Hayle Cornwall

At Kernowsport, we see a lot of Peugeots with AdBlue problems, but until now we had never had a Peugeot 508 in the workshop. This one was a tidy example and came to us in Hayle after displaying an engine management light, but with no obvious performance issues. After a full diagnostic check using our professional-grade equipment, the fault pointed to the AdBlue system. The decision was made to carry out an AdBlue delete, giving the car a permanent solution and saving the owner from costly repeat repairs. As with many French cars, the ECU write procedure had a few quirks. During the process, the wipers, ABS system, alarm, and various warning lights all kicked into action — it felt a bit like sitting in a Christmas disco while the remap was applied! Thankfully, the job was completed quickly, and the owner was soon back on the road with a smooth-running, fault-free Peugeot 508. Another happy Kernowsport customer in Hayle. Why Peugeot Owners in Cornwall Choose Kernowsport 🚗 Fix Your Peugeot AdBlue Problems in Cornwall If your Peugeot 508, 308, 3008, 5008, or Expert van is suffering from AdBlue, DPF, or EGR issues, Kernowsport can help. 👉 Learn more about

A30 roadworks milling machine in Pool Cornwall with AdBlue fault fixed by Kernowsport

A30 Roadworks Milling Machine AdBlue Fix in Pool Cornwall

Job number five today was an unusual one for Kernowsport. Our friends at Harts Haulage in Pool have the contract to transport and process the road surface from the A30 resurfacing works, which are taking place every night for eight weeks. With more than 30 vehicles and staff on site, the job is a huge logistical operation. At 1:15pm we received an urgent call — the milling machine used to rip up the old road surface had stopped working due to an AdBlue fault. Without it, the entire resurfacing project would grind to a halt. Fortunately, Kernowsport is fully equipped to work not just on cars and vans, but also on HGVs and plant machinery. We headed straight up to Harts Haulage in Pool, removed the ECU from the milling machine, and quickly resolved the issue. A pretty unusual job for us, but we’re proud to have played a small part in keeping the A30 project on track and helping reduce disruption for road users in Cornwall. Why Choose Kernowsport for Plant, HGV and Commercial Vehicles in Cornwall? Whether it’s a Mercedes Sprinter van, a Vauxhall Vivaro, or even a milling machine, Kernowsport has the skills and equipment to keep

Vauxhall Insignia BiTurbo diesel AdBlue fix at Monkey Tree Holiday Park Newquay Cornwall by Kernowsport

Vauxhall Insignia BiTurbo AdBlue Fix in Newquay Cornwall

In what was possibly our last holidaymaker rescue job of the year, we were called to Monkey Tree Holiday Park near Newquay to resolve an AdBlue issue on a rather special car — a Vauxhall Insignia BiTurbo diesel. This wasn’t just any Insignia either. According to its owner, there are only six of these top-spec BiTurbo models in the UK, and all of the owners know each other! Because of its rarity, the Insignia had a slightly unusual setup, with an ACDelco ECU instead of the more common units we usually see. It took a bit of extra time to track down the correct mapping solution, but once we had it, the process was smooth and effective. Not only were we able to permanently resolve the AdBlue countdown problem, but we also supplied the customer with the fixed ECU file so the solution could be shared with the other five owners across the UK. It’s not often that we get the chance to help an entire model range, but there’s always a first time! Another Cornish holiday saved, and another happy Kernowsport customer back on the road with peace of mind. Why Vauxhall Owners in Cornwall Choose Kernowsport If your

Kernowsport mobile ECU service in Redruth Cornwall fixing Land Rover Discovery Sport

Land Rover Discovery Sport AdBlue Fix in Redruth Cornwall

This customer found out the hard way just how serious AdBlue issues can be. Once the countdown starts, it’s only a matter of time before the vehicle becomes disabled and refuses to start unless the fault is properly fixed. After a visit to the local Land Rover dealer, the owner of this Discovery Sport in Redruth was faced with a repair quote that left them shocked. Thankfully, they called Kernowsport instead. We were able to fit the Discovery Sport into our schedule on the way to a job in Newquay, and we quickly resolved its now terminal AdBlue problems. This particular model was the popular 2.0 diesel, and it turned out to be a real pleasure to work on. The fix was straightforward and efficient — something we always like! Even with the Cornish weather blowing a gale, the job was completed an hour quicker than expected. The owner was delighted to have their Land Rover back in full working order without the hefty main dealer bill. Next stop? Newquay, for yet another AdBlue job. Why Land Rover Owners in Cornwall Trust Kernowsport If your Land Rover is showing an AdBlue countdown or warning light, don’t wait until it becomes

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

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

Kernowsport performing AdBlue delete on Jaguar F-Pace in Hayle Cornwall

Jaguar F-Pace AdBlue Fix in Hayle Cornwall

Another AdBlue fix, another holiday camp, and another holiday saved! This time, we were called to Atlantic Coast Holiday Park in Hayle to resolve an AdBlue countdown fault on a Jaguar F-Pace. With only 300 miles left on the clock before the vehicle would refuse to start — and a long journey home ahead — it was essential to get the issue sorted quickly. Throughout the summer, we’ve seen many similar callouts, often to holidaymakers across Cornwall. On average, we’ve helped around 60 vehicles a month, ranging from Minis to Maseratis. It’s a lot of work, a lot of miles, and plenty of challenges — but it’s always rewarding to see another customer back on the road stress-free. Even though the holiday season is winding down, AdBlue jobs still make up more than half of our workload, proving how common and frustrating these faults can be. Whether it’s a Jaguar F-Pace, Range Rover Evoque, or VW Crafter camper, Kernowsport is here to keep you moving. Why Choose Kernowsport for AdBlue Fixes in Cornwall?

Kernowsport mobile ECU van working in heavy rain in Cornwall

Citroën DS4 AdBlue Fix in Perranporth Cornwall

This job was a little unusual and highlights how often we’re called out to help holidaymakers in Cornwall. A gentleman from Nottingham rang us in a panic — his daughter had just arrived at a holiday camp in Perranporth with an AdBlue countdown warning on her Citroën DS4, and she had two weeks of holiday left before driving home. At Kernowsport, we know how stressful these situations can be. When possible, we’ll always try to accommodate same-day visits, and that’s exactly what we did here. Despite the worst weather of the year — and getting absolutely soaked in the process — we headed off to Perranporth and successfully resolved the AdBlue issue. The DS4 was back to normal, and the lady could enjoy her holiday without worrying about being stranded. This was actually the second AdBlue delete of the day, and on both occasions the heavens opened, leaving us drenched. Luckily, our Kernowsport van is fully equipped for all-weather conditions, including a diesel heater to keep us warm while working.

Mercedes V-Class 250 in Wadebridge Cornwall after remap and AdBlue delete by Kernowsport

Mercedes V-Class 250 Remap & AdBlue Delete in Wadebridge Cornwall

While working on another job in Bodmin, we were stopped by the owner of an immaculate Mercedes V-Class 250 diesel who was keen to know if we could improve its performance. After a chat, we arranged to head over to Wadebridge the following day to give the V-Class the full Kernowsport treatment. Overnight, the owner had done some research on AdBlue issues and decided to tackle the problem pre-emptively. Rather than waiting for warning lights or countdowns, he asked us to perform an AdBlue delete at the same time as the performance remap, ensuring peace of mind for the future. This turned out to be a relatively straightforward job — and for once, a Mercedes was well behaved! The results were excellent: a strong performance gain over standard, smoother drivability, and no more risk of future AdBlue faults. The owner was delighted, and that’s exactly what we like to see. Why Choose Kernowsport for Mercedes Remapping in Cornwall? If you own a Mercedes V-Class, C-Class, or Sprinter, Kernowsport can help keep it running at its best with safe and reliable ECU tuning.

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.

Kernowsport ECU bench-level AdBlue fix on Hyundai Santa Fe in Cornwall

Hyundai Santa Fe AdBlue Fix in Mawla near Portreath Cornwall

We’ve lost count of how many holidaymakers this year have called us with an AdBlue countdown warning on their vehicles. These issues often leave drivers with too few miles left to get home before the car enters no-start mode. Joyce from Essex rang us one evening with exactly this problem on her Hyundai Santa Fe. To make matters worse, she still had a whole week of driving planned in Cornwall before heading back home, so the issue needed resolving straight away. The following morning, we travelled to her holiday home in Mawla near Portreath. As usual for Cornwall, there was no phone signal — but thankfully our Starlink satellite internet on the Kernowsport van kept us connected so we could get the job done. This turned out to be a bench-level job, but we were able to carry it out without removing the ECU from the vehicle. Once complete, the AdBlue fault was permanently resolved, giving Joyce and her husband the peace of mind to enjoy their holiday without worrying about countdowns or breakdowns.
