As the title suggests, I ask if, according to your experiences ? can clean the fuel injectors of a fuel (Bosch Audi) over the counter without the aid of the equipment to the ultrasound. Then without gasoline additives or stuff like that. In the net you can find the video of cleaning the injectors at the counter facts with a given pressure (usually 3-4 bar) and liquid too diluted and with a device for opening and closing manually controlled during the cleaning process.
May work a thing of this kind of the actual inconvenience resulting from time lost, etc etc? I thank those who have actual experience to report about it.
