Diagnostics, Mobile Call-Outs & Electrical Testing
Mark Warren Automotive provides diagnostics-led fault finding using a professional Launch X431 diagnostic platform, supported by practical mechanical and electrical testing. Our goal is to identify the cause of the problem, not simply clear a fault code.
Mobile Vehicle Diagnostics — Johannesburg
Local call-out diagnostic assessments by appointment in Johannesburg and surrounding areas, subject to location and availability. Suitable for initial investigation of warning lights, starting issues, intermittent faults and drivability problems. More extensive testing or repairs may require a workshop visit.
Battery, Starting & Charging System Tests
Assessment of battery condition, cranking performance, alternator output and charging-system operation using appropriate diagnostic and electrical test equipment. Available testing functions depend on the vehicle and connected equipment.
