Hi I hate to say this but most of your faults would lead back to the battery as when they go down hill it causes all sorts of weird and wonderful faults, if its the original battery it should have the year of the battery on the unit somewhere, if in doubt change the battery clear all faults and start again, see which faults reappear that will give you a good indication of what is realtime and what is caused by voltage draw being low, depending on your milage my pure guess is that the oxygen sensor is failing and your throttle body has excessive carbon this throws up ABS and traction control lights as both units are switched out when the engine is struggling to produce enough power as both these elements are a massive drain on engine power, I would stick with VCDS as it is a manufacturer specific software.
