Oh well here goes, new member so this could end up anywhere!
I have a 2000 RX300, owned for 2 years an it's run perfectly even with these two warning lights on. I understand that it will fail the MOT this year if these lights are not put out. I know the fault codes and have investigated the problem from time to time but one piece of information that continues to appear, mainly on the US site, is that a small pipe into the air filter box has been disconnected causing all manner of warning lights. I have searched endlessly for this pipe and cannot find it or any connection for a pipe on the air filter box. Is this pipe common to all models, if yes can anybody tell me exactly where it is?
