I know i've asked this question before (just spent 2 hours googling trying to find the answer) so 'scuse me if i ask again.
Rear height sensors on D2 with Air suspesion. The bottom bush has rotted through and is in danger of falling off. Typical Landrover means you've gotta change the whole sensor unit rather than the broken bush.
Can i change the whole thing without having it re calibrated on Testbook??. Sods law that it should go now when i've got 15 mins before the nearest dealer with testbook shuts and i wanted to use the car tonight.........
