So i had the fuel injectors checked, and they're done, spray pattern is way off on 2 of them and one of these 2 do only get like 60-70% of their capacity.. 1 is good and 1 leaks after shutoff. they had them cleaned ultrasonic the whole morning but they don't get better. Going to get me 4 new ones. The rs4 injectors are sometimes used but they're not ideal because they have a different spray pattern then the S3 injectors and the RS4 injectors are designed to work at a different rail pressure. They do work on a 2.0 BUT there are issues when using them. Going to get me 4 new S3/R20's, too bad that they aren't cheap, gonna cost me another 450 euro's..
