Do I need a diagnosis before requesting a repair?
Not always, but the enquiry should distinguish a confirmed fault from a suspected one. Investigation may need its own scope and estimate.
Can a repair estimate change?
It can when inspection reveals different or additional work. The operator should explain changed findings and obtain approval before extending the job.
Can I choose which parts are used?
Ask the operator what options are appropriate for the vehicle and repair. Availability, specification and warranty terms need confirmation for the actual job.
What records should I keep?
Keep the estimate, approval, invoice and any supporting test or parts information with the vehicle history.
Are repairs guaranteed?
No warranty or guarantee is claimed by this demo. A real operator must publish accurate terms that match the work and parts supplied.
