The front of the Bosch manual for the injection system on the 306 HDi says in big red letters, DO NOT USE FUEL CLEANERS/ADDITIVES ON THIS SYSTEM... or words very similar to that effect.
There are baskets on top of the injectors that act as filters, there are filters in the tank pump, and a pre-high pressure filter on the engine too. Cleaning out all those is something the fuel cleaner won't do... if anything it'll just dislodge more crap to block up the injector basket filters!?
I'd save up and get new filters and maybe an ultrasonic clean on the injectors done, it'll make more long term difference than cleaners which Bosch say you shouldn't use!
Tappy injectors seems to be a characteristic, and fuel cleaner won't fix it. Even the very best HDi's I've seen have ticked loudly, while some cars that look like they are on deaths door, had very subtle ticking noises.
