Our second job of the day was another Ford — this time a 2017 Transit Custom Diesel. These vans are among the most popular we see at Kernowsport, and while some are a pleasure to work on, others can be a real challenge depending on the year!
The pre-2019 Transit Customs are relatively quick and simple to remap and tune. The post-2019 models, however, are a different story — their ECUs are locked by the manufacturer, meaning they often have to be removed and sent to Magic Motorsport in Europe for unlocking before we can begin any work.
Thankfully, this 2017 example fell into the easy category. In fact, it turned out to be one of the fastest AdBlue and DPF delete jobs we’ve ever done, taking less than 20 minutes from start to finish — a new Kernowsport record!
🔧 The Job – AdBlue and DPF Delete
This Ford Transit Custom belonged to a local customer from Troon near Camborne, whose trusted garage had recommended us after working with Kernowsport several times before.
The van was suffering from AdBlue and DPF faults, causing warnings and reduced performance. The plan was for the garage to physically remove the DPF, while we carried out the software delete and AdBlue disable — ensuring everything was done safely and correctly.
We headed out to the customer’s site, battling strong winds, heavy rain, and a few flooded roads down a long Cornish track to reach them. Despite the weather, the process went perfectly.
Within 20 minutes, the ECU remap was complete, AdBlue system disabled, and the DPF removed from the software. The van started up cleanly, no warning lights, no limp mode, and no future AdBlue countdowns to worry about.
Another happy customer, another successful job completed, and time for us to head back to Hayle for a well-earned warm-up!

🧰 Why AdBlue & DPF Deletes Make Sense
AdBlue and DPF systems were designed to reduce emissions, but in many cases, they become expensive reliability issues — especially for working vans that cover short distances or idle frequently.
Deleting or remapping these systems (where legally appropriate and for off-road or export use) helps by:
- ✅ Eliminating recurring AdBlue warnings and limp modes
- ✅ Improving fuel economy and throttle response
- ✅ Extending engine lifespan
- ✅ Reducing maintenance downtime for tradespeople
