Audi_do_dat_den & ravashanks - did either of you find a resolution to your pinking in the end?
I have the same issue with almost exactly same symptoms and conditions where it occurs (low revs, under load, warmer conditions seem to encourage).
Mine’s had a carbon clean, newish sparks, injector refresh, new PCV, new optimised map. Thought we’d cured it but it’s recurring a little again now.
Let us know will ya!
