“It just works! Maybe if there's a multi-year 'mess' you have to give it a workout and repeat later, but it does what it was designed to do.”

“It is very difficult to apply the contents of the can to the throttle, in other manufacturers in similar agents there is no such problem, the cost of purchase after all is not low, so it is probably worth working on its application. When working on the car, you need to be careful not to spray, for example, the lamp shade, it will be suitable for polishing, the agent with acetone, so it melts such plastics.”

“Revelation. EGR cooler and manifold like new. Highly recommend (1.9 Jtd 150 km).”

"Ok."

“RECOMMEND!!!!”

“Brilliant product for cleaning carbon build-up from diesel (1.9TDI AUY) intake.”

“It works as much as possible. I used half and the car took a deeper breath. Only you need to be careful and dose gently. In my case, at first it choked the engine a little, so at higher revs (about 1500), while after 2-3 pushes it started to raise the revs on its own.”

“It certainly cleans and you can smell the agent in the exhaust, but whether effectively, it's hard to say, because I used prophylactically after fixing a leak in the intake system. I advise you not to add too much at once. The whole procedure should take about half an hour.”
