The first proper job of the new year took us to Camborne, where we were called out to resolve issues on a VW Golf 2.0 TDI that had been left in limp mode with an engine management light following a DPF delete over the holiday period.
The physical work had already been done, but as is often the case, the software side hadn’t been completed, leaving the car restricted and undriveable.
More Than Just a DPF Issue
On inspection, it quickly became clear that this Golf also had an EGR blanking plate fitted, meaning the ECU still expected emissions components that were no longer present.
This is a common scenario—and exactly where professional ECU calibration is essential. Without the correct software updates, fault codes, limp mode and warning lights are unavoidable.
Prepared for Any Situation – Even Snow and Flat Batteries
Thankfully, all Kernowsport vehicles are fully equipped for on-site work. This one needed a little extra care, as it was also suffering from:
- A flat battery
- Freezing conditions
- Around two inches of snow
Using our CTEK battery conditioner, we stabilised the voltage and safely carried out a full OBD ECU write, applying:
✔ DPF delete software
✔ EGR delete software
✔ Stage 1 performance remap
Voltage stability is critical during ECU programming, and this is one of the reasons customers trust Kernowsport to do the job properly.
Back to Life – and Nearly 200 BHP
Once the updated file was written, the Golf fired up immediately, free of fault codes and no longer in limp mode. With just under 200 BHP, the transformation was obvious—and the smile on the owner’s face said it all.
A problem vehicle turned into a strong, reliable, and enjoyable drive, exactly as it should be.
