[DIY] BMW N52 Disa Valve Replacement & Test With Inpa!

If you have a 3 stage intake on a BMW N52 engine, then you have 2 DISA valves. These valves open and close depending on the RPM and Throttle to get better fuel economy and torque in the lower rpm range while being able to open up fully to get more horsepower in the higher RPM range. The problem is they fall apart after a while, the plastic pin can break in the flap and go into your engine if you dont catch it soon (like I did). Here is how you replace your Disa Valve and test it with inpa. 🛢️Check out THE BEST ENGINE OILS list here https://bmw-repairs.com/best-engine-o... 🔧Click HERE for Everything You Need To Maintain Your BMW (All Fluids, Spark Plugs etc) https://bmw-repairs.com/basic-mainten... --------------------------------------------------------------- ☕Was the video helpful?
