Sounds like your clutch cable is about to break BTW. Replace that and it will probably fix ALL the gearbox issues. That accelerator free play? I pointed out earlier the cable had been recently hooked into a different hole at the front? Not to cast aspersions but did they do that to create a fault? Sure looks like it. Allegedly.
Put it in for a mot somewhere and fix the fails list Then head to techenders and start working through the advisory list
Christ, that's hilarious We could all make a list up like that about our buses if we looked hard enough, I'm pretty concerned myself about a missing teaspoon from the cutlery drawer.....
