Hi, well done👍. I would like to do the same…some questions: when you say disconnect the battery, you mean positive and negative or just the negative is enough?, it is necessary to desamble the turbo plastic house from down the vehicle…it is possible to change the tensione from that position too? Are you able to have the strength of 80N from upside as you showed? Or better from down side…if the car is on a lift.. thanks for your answer. In future you can make a video about cleaning the EGR valve…will be very useful 🖐
