(I thought it best to start a new thread with this question rather than hi jack an existing thread).
Like many, I had the misfortune to experience the Water pump, thermostat housing, cooling warning lamp " issue" on my previous GTi, a 2013 PP at around 25k miles.
Did VW manage to resolve this issue in later Mk7 & 7.5 variants, or is still to be expected as we approach 3 years & 30k miles?
