🔥 FROM ROUGH RUNNING TO REFINED PERFORMANCE — ASTON MARTIN DB9
This stunning Aston Martin DB9 arrived at our workshop after the owner had experienced ongoing frustration with a severe rough idle that previous repair attempts elsewhere had been unable to resolve.
Through a thorough diagnostic process, our team identified multiple vacuum leaks caused by a faulty oil separator and leaking injector seals.
🔧 Work completed:
✅ Replaced the faulty oil separator
✅ Replaced the injector seals
✅ Rectified the vacuum leaks
✅ Restored a smooth, stable idle
✅ Performed a Stage 2 ECU calibration
Once the engine was repaired and operating correctly, we completed a custom Stage 2 tune to unlock additional power, sharpen throttle response and deliver a stronger, smoother driving experience.
The result? This beautiful DB9 is running exactly as it should—and performing even better than before.
At SemCar Automotive Group and Euro-Aus Performance, we believe performance tuning should always begin with accurate diagnosis and a mechanically healthy vehicle.
Is your European performance car still not running properly after repeated repair attempts? Let our experienced team get to the source of the problem.
