Exotic car diagnostics done right—by someone who actually understands these cars.

At Charleston Supercar, we specialize in real diagnostics—not just pulling codes. With nearly 30 years of experience and factory-trained drivability expertise, we go far beyond generic OBD tools and parts-swapping guesswork.

 

Whether you’re chasing an intermittent fault, an active misfire, a stuck rear spoiler, or a suspension warning light, we approach your McLaren with the same technical mindset we’ve used to solve the toughest issues at the dealership level.

Common McLaren Issues We Diagnose

  • Check engine lights with vague or multiple fault codes

  • Misfires under load (especially on 570S, 600LT, and 720S)

  • Electrical gremlins or CAN network communication errors

  • Suspension height, active damper, or “Vehicle Lift System” faults

  • TPMS or electronic parking brake errors

  • Crankcase pressure and PCV-related issues

  • Spoiler actuator or aerodynamics system faults

 

🧰 Many of these problems are misdiagnosed by shops using generic scan tools or unfamiliar with McLaren systems.

  • Deep drivability and electrical systems expertise

  • Advanced scan tools and manufacturer-level diagnostic logic

  • Detailed failure verification—no guessing, no parts cannon

    “Anyone can read a code. Very few know what to do with it.”
