AudiSpecialist.
Independent Audi specialists in Hurst, Berkshire. RS3, S3, TTRS and the wider S and RS estate. Diagnostics, calibration and engineering carried out with dealer-tier tooling and an enthusiast's eye.
Why owners come to us
A specialist for the Audi platform.
Audi RS and S cars reward properly engineered work. The 2.5 TFSI five-cylinder in the RS3 and TTRS, the EA888 in the S3, the 4.0 TFSI V8 in the RS6 and RS7. Every one of these platforms has known quirks, well-documented sweet spots and very specific calibration needs.
Whether you're booking in for a routine RS3 service, chasing an intermittent EPC fault on a S3, or planning a full bottom-end refresh on a TTRS, we'll work through the car methodically and explain everything we find before quoting.
