BMW VANOS and Timing Chain INPA Diagnostics

Ever wondered how the Vanos units are doing and if your timing chain is stretching? What about that rattily valve train in your BMW Engine? Here's how to find out using INPA diagnostics. I go through each page of INPA diagnostics for the valve train and explain what the values mean.
I also explain the most important page for seeing how much wear there is in the timing chains, guides and tensioners. These diagnostics are for all BMW engines with Vanos and/or Valvetronic systems.
