Service completed - 5 ltrs, Mobil One 0w40 (£34). Forte engine flush and oil fortifier (£12). Fuel filter, oil filter, pollen filter (£21). Labour (£25). Total (£92)
N75 valve replaced (£28) from German Auto Spares - Boost issues have now been resolved, turbo now spikes at 21.6psi and holds at 17.5psi..... Cracking job Gromit

BSH PCV kit also installed, rough idle resolved and an altogether much sturdier piece of kit than the oem cheap plastic version.
Heko deflectors also installed, not my favourite thing and certainly not overly aesthetically pleasing, but they don't half reduce wind noise and stop all the bastard rain falling in your lap too!
