Diagnostics

Finding out what a warning light actually means, and what it will cost. These cars are a network of modules rather than a set of parts, so the question is less whether a workshop can read a fault code than whether it can code and reset the module afterwards.

What diagnostics involves

  • Reading the fault across modules, not just the light on the dash
  • Coding and resets afterwards, which is where most independents stop
  • A written account of what the codes actually said
  • Often an hour’s work to find a fault that takes ten minutes to fix

Compiled by the register from what workshops on it are asked for. Not advice about any individual car, and not a specification any workshop has agreed to.

What to ask before you book

  • Which diagnostic system they run, and whether it is the factory one
  • Whether they can code and reset a module or only read from it
  • What the diagnostic hour costs, and whether it comes off the repair
  • Whether they have seen this fault on this model before

Verified listings answer several of these on the page already — the ones confirmed at inspection are marked as checked rather than stated.
