Mine is still playing up.. even after getting it back from the dealer and them asking me to drive for an hour at 70mph so the regen can reset it hasn't worked a couple months since getting it back.

weirdly when I am on my long drives from down south to Manchester etc after around 1 hour at motorway speeds it kicks into 8th gear for the rest of the journey then once the car is cooled down and I do the journey again won't go into 8th gear until again arund 1 hour at motorway speed.
at one point it would only do it at 84mph and then at 70mph..

with the wait times at the dealerships and them unable to fix I might have to change the exhaust which I was going to do anyway but not sure if to go with catback or opf back
