Interesting, I now look after loads of Foci and have never come across this problem at MOT time,I am always present when the car is going through, a BET is a basic emmission test,I have never heard the tester say " oh yes I have got to jack a wheel up for it to pass emmissions", and If a VOSA man was watching I wonder what their comment would be?. What is worrying is that the VM could actually write this procedure into its software surely knowing the parameters of the BET test, sounds like a cheat to me,
