A price for assessment and a price for an identified repair describe different work. Before dispatch or booking, establish what the quoted stage includes and what happens if the suspected module is not the cause of the vehicle complaint.
Agree the practical details
Ask about testing scope, additional work requiring approval, return arrangements and any installation requirements. Provide the module identification and diagnostic evidence before assuming a price applies. A generic online starting price cannot define every damaged or previously modified unit.
Keep the agreed description with the job reference and make sure the vehicle garage understands what remains outside the bench service. Do not interpret a repair estimate as a guarantee that the whole vehicle will be fixed by that one operation. Clear information helps the specialist assess suitability and helps the customer compare like-for-like proposals. If the fault is still unconfirmed, ask which diagnostic stage should come first rather than purchasing a guessed repair.
