Stone Grey 924S (my wifes daily ) passed it's MOT again today with 1 Advisory-nearside front tyre which I had checked with my tyre tread gauge beforehand & was quite OK but I will be changing both front tyres in the near future-even my friendly tester said at the mileage the car does annually -around 2500 miles-it would probably still be OK next year.
Last couple of years although he passed it ,the CO reading was high at 4.12 % so this year I screwed out the bypass screw by a modest 5 degs & result ,CO reading is 3.5% with HC's also lower.No exhaust tester to check with since it doesn't work since I lent to someone a few years ago but only found this out recently
As the notched wheel spring setting in the AFM was altered many years ago to improve throttle response,this is not a bad result
