What's the difference between dealer diagnostics and a generic scanner?
A generic OBD scanner reads engine fault codes — it sees maybe 5 modules out of the 30+ in a modern car. Dealer-level (manufacturer) tools read every module: transmission, ABS, airbag, body control, gateway, comfort, infotainment, and more. They also see live data, adaptation values, hidden codes and module-specific tests that generic scanners can't access. We use manufacturer-level tools for every job.
My garage cleared the code but it came back — why?
Clearing a code without fixing the underlying fault just resets the counter. The fault is still happening, the ECU detects it, the light comes back on. We trace codes to their actual source — sensor, wiring, mechanical fault — rather than playing whack-a-mole with the warning light.
How long does a full diagnostic take?
A full system scan and report takes 45–90 minutes for most cars. Intermittent faults that need live-data logging or test drives can take longer. We'll always tell you up front what to expect.
Will you do the repair afterwards or just diagnose?
Both. For coding, ECU work, cluster repairs, mileage correction and most electrical faults we can carry out the repair on site. For mechanical work outside our scope (engines, gearboxes, brakes, body) we'll give you a clear report you can take to a trusted mechanic — so they're fixing what's actually wrong, first time.
Do you do pre-purchase inspections?
Yes. A full diagnostic scan before you buy reveals hidden fault codes, recent module replacements, mileage inconsistencies between modules, and any modifications. Worth its weight if you're buying a 5-figure car private.
Do you cover my make?
BMW, Audi, VW Group, Mercedes, Porsche, Mini, Land Rover, Jaguar, Ford, Vauxhall and most Japanese, Korean and French marques are routine for us. Send the registration over and we'll confirm before booking.
