Know Before You Tune. Dealer-level diagnostic capability
Before carrying out any ECU remapping, we always perform a comprehensive diagnostic health check. Using dealer-level OBD equipment, we read fault codes, analyse live data streams and verify engine health - ensuring your vehicle is in the correct condition for tuning. The same rigorous approach adopted by Europe's leading calibration specialists, delivered mobile across Bournemouth, Poole, Dorset, Southampton and Hampshire. Many customers book standalone diagnostics when warning lights appear, even if they are not planning a remap.
Our car diagnostic session provides a complete picture of your engine's current health:
Remapping a vehicle with existing faults - a failing MAF sensor, clogged DPF or weak turbo - can mask problems and potentially cause further damage. Our pre-remap health check identifies these issues so they can be resolved first, protecting your engine and ensuring your remap delivers reliable, long-term results.
Many customers book diagnostics independently when warning lights appear, even if they are not planning a remap. Independent fault finding avoids unnecessary dealer visits and provides honest advice on repair options.
We diagnose all major car brands including BMW, Audi, VW, Mercedes, Ford, Vauxhall, Toyota, Honda, Nissan, Peugeot, Renault and performance marques. Our equipment reads manufacturer-specific codes beyond generic OBD-II, providing deeper insight into your vehicle's systems.
Mobile diagnostics are available across Bournemouth, Poole, Christchurch, Wimborne, Southampton, Romsey and nationwide.
Our engineers regularly uncover boost leaks, failing MAF or MAP sensors, weak turbo actuators, clogged DPFs, EGR restrictions and misfire conditions on petrol and diesel vehicles across Dorset and Hampshire. Identifying these issues before remapping protects your engine and ensures any subsequent calibration delivers reliable long-term results.
Customers in Bournemouth, Poole and Southampton book standalone diagnostics from £89 when warning lights appear - even if they are not planning a remap. You receive a written report with clear, honest recommendations.
Whether you drive a BMW 340i, VW Golf GTI, Audi diesel commuter or Ford Transit van, our diagnostic equipment reads manufacturer-specific fault codes that generic scanners miss. We monitor live data - boost, fuel pressure, lambda, coolant and emissions status - to build a complete picture of engine health before any remapping or repair decision.
