In Willcove's case, I'm guesing it was a "grey import"? This is one of the problems with these cars. They are outside the "system" so VOSA has nobody to go to to get an "official" figure for ther brake test chart. When your car came in, it should have done an SVA test and the car would have been weighed at the time. Ironically, this is one of the situations that helped drive the computerised MOT system! The idea would be that as soon as the tester identified your car (registration / VIN) the computer should have found all its relevant data (brake test weight, emissions etc) and TOLD the tester what to test it to! Clearly the system isn't quite working as intended just yet!
The car is a Mitsubishi Pajero which underwent SVA. However, the system knew of the car but didn't know much about it and all the details had to be entered by hand. When I booked the MOT, the tester asked me to bring my V5 because he apparently he would have difficulty doing the test without the document number. BTW, I shudder to think what would have happened if I'd bought one of the other cars on my shortlist: Mitsubishi Delica L400 or Mazda Bongo SGL5 - neither of which have UK equivalents.
The system also didn't get my other vehicle (a Citroen Dispatch) right and incorrectly flagged it as two-seat, 1.9D, 815kg payload whereas it is actually a three-seat, 2.0HDi, 900kg payload variant. So I suspect that there are serious problems with the MOT system data. That said, according to a DVLA report over 70% of their records contain one or more errors, so the data quality issues of the MOT system aren't surprising. What is crazy is that the Government are rolling out system after system based on the flawed DVLA data.
That said my original post was to highlight the problem of using unladen weight for the brake test without actually weighing the vehicle at the test station. They could do this very easily just by fitting load cells to the carlift they use for most of the test. The unladen weight changes over the life of each vehicle. They all put on weight due to accumulation of detritus, corrosion, fitting of accessories and even when new, the weight of two examples of the same vehicle can be different because of manufacturing tolerances, difference of options fitted, etc. So the wallchart that's been used for years, in which the weights are specified to the nearest kilogram, are inaccurate. In borderline cases, this can result in a pass that should have failed, and vice versa.
