The Data Bottleneck
As vehicles become increasingly software-defined, the ability for independent workshops and tuners to access in-vehicle data has become a major point of contention. In March 2026, CLEPA, the European Association of Automotive Suppliers, highlighted that the European Commission’s Data Act requires further guidance to ensure a level playing field. For the aftermarket, this is about more than just diagnostics; it is about the ability to calibrate advanced suspension systems, tune engine management units, and perform complex retrofits.
Impact on Tuning and Customisation
Modern performance parts—from advanced coilovers with electronic damping control to sophisticated LED lighting retrofits—often require integration with a vehicle's onboard systems. If manufacturers restrict access to this data, the ability to install and calibrate aftermarket performance parts is severely hampered. Ensuring that independent businesses can access this data is vital for the health of the European tuning scene, allowing for the continued innovation of performance upgrades.
Takeaway
Data is the new frontier of the automotive aftermarket. As regulations evolve, the industry must remain vigilant to ensure that car owners retain the right to modify and repair their vehicles using high-quality aftermarket components.
