I did a diesel purge over the weekend using Liqui Moly diesel purge fluid.
Consists of sending an 'injector cleaner fluid' directly into the injectors after bypassing the fuel feed from tank. Then you run the engine using this for about 15-20 minutes.
Loads of reviews online about this, some video tutorials too.
I found it worked well. car seems to rev freely, its much smoother and more responsive.
Worth doing for the higher mileage disels in my opinion, mine has 88k on it and has used a mixture of fuels thorughout its life. More recently I have been using shell only, every couple of fills I use v-power.
