Our second job of the day was a great local one — a 2.0 Audi A4 Avant from Redruth, brought in to Kernowsport for a DPF delete and Stage 1 performance remap.
The owner had been experiencing intermittent engine management lights, with fault codes indicating injector and glow plug problems. However, these weren’t the true cause — the real issue was excessive back pressure from a blocked DPF (Diesel Particulate Filter).
This is a common issue we see on a lot of vehicles: the sensors detect pressure problems caused by a blocked filter and wrongly assume a hardware fault. Once the DPF is cleared or deleted and the pressure normalised, these “false” injector or glow plug errors usually disappear entirely.
⚙️ DPF Delete & Power Boost
After diagnosing the issue, we carried out a DPF delete and reprogrammed the ECU to safely remove the system from the vehicle’s software.
With the blockage removed, we took the opportunity to give the car a Stage 1 performance remap. The results were impressive — the power increased from 140bhp to just under 200bhp, giving the car a smoother, stronger drive and noticeably better throttle response.
If you’re curious about what kind of gains your vehicle could see, check out our Performance Tuning page for examples and options.
💨 Improved Driveability & Reliability
DPF issues not only reduce performance but can also lead to unnecessary stress on other components such as the turbo, EGR valve, and injectors. By resolving the DPF problem properly and applying an ECU remap, this Audi now drives like new again — stronger, cleaner, and more efficient.
