It hardly takes sixty minutes or sometimes, two hours. However, if additional work is required then it might add some extra time to it. The time is taken for your car’s diagnostic test also depends upon the car’s model and year. Usually, old equipped cars do not match with modern tools or are poor for it, hence in such conditions, the time might vary. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
