Saturday solutions. Range Rover Vogue, sorted. 🐺

Triple job this one — AdBlue, EGR and DTC all handled in a single session.

ECU read on the bench (firmware update on this one), original file secured before any changes, then every solution mapped cleanly into the calibration. Road-tested and verified on live data before it left.

No warning lights. No drama. Weekend doesn’t mean we down tools — if you need it sorted, we’re on it.

Precision in performance, every time. ⚙️

Flashback Friday 👻

We carried out this BMW M3 DTC delete around 3 years ago — clearing ghost engine codes and getting the dash back to clean.

Old job, same Merlin process:
diagnose, backup, calibrate, test ✅

Got warning lights that keep coming back?
