This was our second EGR delete on the same Audi A3 2.0 TDI model in just three days, underlining just how common EGR-related faults are on these vehicles—particularly across the 2007–2013 model years.
This particular car was an early 2007 Audi A3, suffering from the classic symptoms we see time and time again:
- Persistent EGR fault codes
- Limp mode while driving
- Poor drivability and reliability concerns
Mobile ECU Work Near Penzance
The job took us to Praa Sands Holiday Park near Penzance, making this the second vehicle we’ve repaired on-site within a week, the other being a BMW 3 Series.
It was good to see the area recovering after recent storms. When we last visited, there was significant damage across the site, but this time most of the fallen trees and storm debris had been cleared, and things were starting to look more normal again.
The Audi’s owner lives and works on site, so restoring reliable transport was essential.
Professional EGR Delete Using Alientech KESS 3
We carried out the EGR software delete using our Alientech KESS 3, which is our go-to tool for Audi and VW Group vehicles. While we also run Magic Motorsport FLEX and Autotuner as backup systems, the KESS remains our daily driver due to its reliability and speed.
The ECU file was securely uploaded via our Starlink connection to our long-term calibration partners at Viezu, allowing us to:
- Modify the EGR strategy correctly
- Retain the original factory file for safety
- Ensure a stable, repeatable solution
Once written back to the vehicle, we cleared all fault codes, carried out checks, and confirmed the Audi was fully out of limp mode and driving normally again.
