Audi B9.5 A4 / A5 2.0T

ECU Unlocking, Tuning & Dyno Results

A locked ECU does not have to end your tuning plans. Vollux can unlock and custom tune supported B9.5 A4 and A5 ECUs in-house, with AWD Dynojet testing available under the same roof.

Compatibility depends on the exact ECU and software—not the facelift badge alone. We confirm the access method before scheduling.

Not sure which scope applies to your car?

Send the year, model, VIN, transmission, software, modifications, fuel, warning lights, and goal. Vollux will confirm support and the complete price before scheduling.

Availability, software access, recommended scope, and pricing are confirmed for the exact vehicle before work begins.

Unlock when needed. Tune in-house.

Our 2022 A5 example required an in-house ECU unlock; our 2021 A5 example did not. Both received custom ECU tuning at Vollux. The exact ECU and software determine the access requirements. Explore our unlocking capabilities or send your vehicle details to check support.

Only buy the software you need

On supported applications we can tune directly, without requiring a separate third-party flash-platform license. Transmission tuning is optional and only offered where the controller and software are supported.

Vehicle & model-year examples

Representative U.S.-market examples for this engine platform—not an exhaustive compatibility list. Years shown are model years.

VehicleExample model yearsGeneration / engine
Audi A5 2.0T2021B9.5 / F5
Audi A5 Sportback 2.0T2022B9.5 / F5

These are the two documented shop examples. A facelift badge alone does not establish ECU unlock requirements. A4/A5 engine and software versions are checked individually.

Final compatibility, unlock requirements and transmission tuning availability are confirmed by VIN, engine, ECU and current software before quoting. Check my vehicle and get a quote.
