Took my A3 for a "free" mot today. Waited for it for 2 hours. I was told it failed on front brake pads being less 1.6mm. I said they are not, I checked them on the weeked. I asked to see the MOT tester and I did, He agreed the outside pad had 4mm on it but he couldnt see the inside pad clearly so he failed it. I know it was fine because i took them out saturday to check, only a ten min job. So I proceded to jack the car up in the car park and take the pads out and took them in to the service manager. He took them away to the MOT tester and came back 10 min later and said he still wont pass it! I ask for the apeal forms and left. Took it for another mot this pm and passed no problem! He said theres loads of pad left. Im going to be kicking off bit time with audi tomorrow!
