Well my 3.7 went in for it's MOT today. I've been sweating a bit because the MOT had ran out 2 weeks ago... About a month ago I was doing a pre MOT check and noticed the short brake line from the front calipers to the flexi-hose were a bit a corroded and I decided to them replaced only to discover TPS had no UK stock... The '8 was laid up while they arrived with no front calipers and a bleeder valve in the flexi-hose to stop any fluid leaks. I maybe could have bent my own with copper but the originals are steel with the PVC coating and are only £8 each. Work then got in the way and the MOT lapsed. Then when reinstalling the calipers I emptied the brake reservoir and got air in the master cylinder
Bled the lines, got a test booked and now I can stop sweating as it passed with no advisory notices.
Now at 91k and touch wood she's been fairly good with no serious problem or electrical gremlins except for a stuck thermostat 18 months ago.
