Peugeot 1.6 Bluehdi N75 Problem and Solution The N75 valve problem I experienced usually gives an error code for this valve or the hoses are punctured. However, my 2016-1.6 Bluehdi did not give any error. No hose was punctured. It caused low performance, high fuel consumption, jerky start, incorrect atmospheric reading of the air bar. Due to inexperienced technicians, they removed the Turbo wesgate and changed its setting. They completely damaged my vehicle and started to enter protection mode. As a result, I bought a new Turbo and we went back to before the turbo was damaged. Why does it burn a lot? Why does it start jerkily? Why does it lose performance? The solution is that I bought a vacuum pliers for testing the N75 as I watched in the videos. I tested 2 new N75s that I bought from the service and they turned out to be defective. I decided to buy them from a spare part shop I know by testing them. One attempt was defective and I asked the part shop to try another one and the result was good. Even the part shop was surprised but the testers wrote that 50% of the time it turns out to be defective and it turns out to be defective. It happened to me so that it could help someone else. I passed out.
