I’ve got about 4ish months left of my technical training, and in Nov. I am going for my last 3! Engine Performance and the two Trans./Drive Trains. Would be pretty cool to leave a Master Tech. but there is Jan. as well.
My A4 test had a major amount of just wear and tear on parts and being able to understand noise complaints. The best trick I learned was to sit there during the test and position my hands the way caster, camber, and toe were showed. Helped out a lot.
A5 is pretty basic. As long as you have an understanding of a few noises and a general concept of pedal problems, process of elimination isn’t that bad on brakes.
Good luck, and if you have any questions I can try my best to help.
