1) Firstly i would look to reset the adaptations and then set the teach in feature again and see how that goes and also look at the history of the software to see if it has the latest updates. Upgrade the software if required. Secondly the valve body gets sticky pistons and would need to be removed to test out on the bench to see if that requires replacing. Thirdly if that fails and the thump has been going for a while, there is a fair chance the clutch packs are worn and the trans requires rebuilding or replacing.
2)The brake lights could be a stop light switch
3)These engines are prone to leaky vac pumps at the rear of the cylinder head, i have a repair kit for these now and the cam cover gaskets leak like crazy as well. If it has suddenly developed heaps of leaks, like the sump and cam sensors as well as the above, and everything has started leaking, then i would recommend changing the PCV valve and the hoses as the crank case over pressurizes and causes the failure of the seals.
