Vauxhall Astra 1.6 CDTi Remapping

Independent Stage 1 ECU remapping for the Vauxhall Astra 1.6 CDTi (2015–2021), subject to a suitability check. Workshop or mobile, same price either way, from £135.

The Astra 1.6 CDTi is a common sight on UK roads, and a frequent candidate for straightforward Stage 1 or economy-focused work.

What to expect

Remapping the Vauxhall Astra 1.6 CDTi

A Stage 1 remap recalibrates the factory ECU software to improve throttle response and smooth out power delivery, within limits appropriate for a standard, unmodified Vauxhall Astra 1.6 CDTi.

As a turbo diesel, this platform is also commonly approached for economy-focused tuning, which can improve drivability and reduce gear changes on longer journeys. We don't publish generic bhp or torque figures, since actual results depend on the specific vehicle's condition, mileage, and history, confirmed properly during a suitability check.
