Services
Servicing
Our servicing packages cover Basic, Interim, and Full annual checks for all vehicle makes. Using manufacturer-approved diagnostics, we evaluate critical components including engine performance, brake systems, and fluid levels. Each service includes oil changes with OE-specification lubricants and comprehensive multi-point inspections to prevent mechanical failures.
MOT Testing
We conduct thorough MOT examinations assessing vehicle safety standards and emissions compliance. Our technicians inspect steering, brakes, lights, and structural integrity while providing transparent defect reports. Failed MOT repairs are prioritised with competitive pricing to ensure roadworthiness restoration.
Cambelt Replacement
Specialist cambelt changes include OEM parts installation and associated component replacements. We follow manufacturer guidelines for tensioner and water pump upgrades during replacements. Diagnostic checks ensure proper valve timing synchronization post-installation, preventing engine damage risks.
ECU Remapping
Our remapping services enhance engine performance through ECU software modifications. Using Shark Performance and ECUTek tools, we optimise fuel delivery and ignition timing for increased power output. Bench-flashing techniques ensure precise calibration while maintaining drivability and emissions compliance.
4 Wheel Alignment
Hunter Pro-Align equipment enables precise toe, camber, and caster adjustments. We correct thrust angle deviations and suspension geometry issues affecting tyre wear. Post-alignment verification ensures optimal handling characteristics and improved fuel efficiency through reduced rolling resistance.
