Diagnostic & Programming

Diagnostic & Programming Service

At KHN Services we use the latest state-of-the-art car diagnostic test equipment to help troubleshoot system warnings and check engine lights to identify issues early before a possible component failure occurs.

Our diagnostic equipment checks for faults with engine management, electrical systems, lights, emissions, tyres and more to quickly identify any potentially costly problems.

Our trained technicians can then assist with advising you of any recommended repairs to fix the problem, reset the engine management or warning light and prevent further damage in the future.

The standard diagnostic check can take up to 1 hour. However, if additional time is required to complete the diagnostic check, a KHN colleague will contact you for approval to proceed. Programming & Coding Services on many makes and models provided by KHN Services.
