Just after the MOT on my daughter's Seicento three years ago I gave it a routine service and found the rubber bushes on both sides were past their best. The car had been given several advisory notes at the MOT, brake imbalance, rusty brake pipes (just where the flexible pipes are crimped in), exhaust emissions, an oil leak on the engine and the colour of the indicator bulb, no mention of the rubber bushes.
The rust on the brake pipes was very superficial, the 'oil leak' was a dribble left from when I had topped the oil up, the 'wrong' colour of the bulb was barely detectable. I did not think that the brakes were out of balance but took the car to a local garage for their opinion, they tested it and the results were fine, they also checked the exhaust emissions, which were fine.
Since then she has moved, she now takes her car to a different main agent for MOT and has had no advisory notices until this year when they mentioned that one of the bushes was slightly slack. I will probably deal with the buses before the next MOT when it will have been four years since Ifirst noticed it, and only one year since it was flagged up at MOT!
