so your telling me that they ALL STRICTLY ADHERE to the book mmmmm how come my van fail on an obtruction in the windscreen (sticker in the passenger side mind detailing what the window was for )and he had it put in for me while it was there for the mot and a tyre that was supposedly below min depth 2mm (1.6mm) min across central 3/4 i must have t t across my fore head
If you're not happy ask to see the section in the manual that he's failed it on. They have to have the manual and they have to show it to you when requested.
Sticker isn't a problem as you just remove it in front of him and he's then required to do a free retest. Did you check the tyre depth yourself inorder to dispute his measurement. Though to be honest taking a vehicle in with a tyre that close to been bald is a no-brainer really..
