Tamm Auto Service’s diagnostic fee is not published here as a fixed amount. For the San Francisco workshop on Geary Boulevard, ask for a quote that identifies the testing scope and how extra diagnostic work is approved.
What makes two quotes different?
One quote may cover only retrieving codes; another may include investigation of an intermittent fault. Explain when the problem appears and ask what the initial charge buys.
What comes after the assessment?
Ask for the findings and a separate repair estimate. Read the diagnostic preparation guide before booking.
Is the fee automatically credited toward repairs?
Ask Tamm before authorizing testing. This site does not promise that diagnosis is free or that its cost will be deducted from a later repair.
