Glad you're back mate, your car was always one to watch... As for the advisories it sounds like a pisstake... I had a long list of them when I first got my car, including the fuel filler pipe being corroded. Year later I had the car MOT'd and asked them to see how it was, there was no issue. The year after that I went back to the original place, same tester, checked the advisories... Nothing... I said to him "Wow, Toyotas are f*cking amazing cars" he said "yeah they're ok" I then explained to him how over the last two years, the car had magically healed itself of all these issues he had previous found... He had literally not a word to say, told his manager and made it clear that the business I work for would no longer be taking the company vehicles there because of them trying their luck.
Watch them mate. Very rare these days that anyone with a trade is an honest man and will try and lever the extra cash from your wallet. Feel free to be petty enough to ask the advisor to point out all the problems, if they wanna treat you like you're clueless, act clueless... Get them to point out what the advisory is exactly and why its a fail... If you want to give the impression you'd have the work done there it'll help Also may be worth swinging by a different mot place and asking someone to look over the advisories and slipping them some cash for their trouble.
