Re: Alternator and Battery Problem
you oil hadn't been fully changed since february, depending on the milage you've covered since then that could be considered old, and it would almost certainly be black. was it really neccessary to change it? hard to say. was it a bad idea to change it? definately not.
you should always change suspension, steering and braking components in pairs, if you change one side and not the other you usually need to change the other side shorty after, so your ball joint issue is no surprise. it may have passed MOT in february, that doesn't mean it would have passed in march.
