What affects the price
- Whether the fee covers reading the fault codes only, or genuine investigation of the cause
- How long the garage allows before charging further diagnostic time
- Whether the diagnostic fee is deducted from the repair if you go ahead
- Whether the vehicle needs manufacturer-specific equipment
When a cheap price is a warning
A very cheap 'diagnostic' is often just a code read, which tells you which system reported a fault but not what caused it. That is a starting point, not a diagnosis, and paying twice is common.
What to ask before you book
- Is this a code read or a full investigation of the cause?
- Is the diagnostic fee deducted from the repair if I go ahead with you?
- What happens if it takes longer than the time included?
- Will I get the findings in writing so I can get a second quote?
