Wynns EGR clean i used that when i did my EGR, make sure you wear gloves though if you do get it, it melts the carbon into liquid it is like carb cleaner but 100 times more concentrated/powerfull.
I've not seen that before, being generally sceptical of magic additives - bad experiences with Radweld and Bar's Leaks many years ago (they stopped the leak all right, and then went on to clog up the radiator and pipes).
How is it used? Do you just spray it into the inlet system and wait? I expect you get clouds of smoke and a bad smell out the exhaust, at the very least
Did it do a good job of cleaning out the EGR?
