Strange how differing the range/standard of MOT inspectors can be.
The MOT on my Jazz had an 'advisory' in a similar vein to what Jock said about undertrays 'obscuring some underside components'.
This week however, I took the better half's Audi for its MOT and the tester took a lot of time examining the 'covered underside components' from above (and below obviously) and passed it with no advisories.
I 'get' the standards, but I also wonder if the first examiner had followed the same mantle as the second, it would save the 'perceived blemish'?
As a footnote, nothing wrong with either testers standards, it's just the anomalies that seem to exist in the procedures.
