I made the first revision of my car RR TDV6 L405 2016 (he was 12.000KM), for a period of one year. I have checked the service note and saw that put several products the most, the TUNAP brand to circuit cleaning, among other things. I know that the dealerships always push unnecessary products, but I like to know if the same thing happened to someone and this can cause some damage in the car engine. They used a TUNAP T-157 to clean the engine. 12,000 km, I find absurd.I dont need this. My car is new, dont need this stuff.
