I have this problem with my 2cv at Mot time with the tester who is about 35
Year 1: Fail - Reason, corrosion of the coolant pipes - The car is air cooled, he was looking at the exhaust manifolds
Year 2: Fail - Reason, Passenger front door lock inoperative - I pointed out that you need to unlock them with the key first.
Year 3: Fail - Reason, headlights will not switch off. The tester managed to bust the light switch mid test with the lights on...
Unfortunately the place burnt down about 6 months ago (wasn't me Guv) and they currently can't do Mot tests so I'm going to have to start again with a new tester. I dread to think what they would have made of my Morgan!
