HI guys,

I was asking for valve cover gasket change some time ago. Me and my friend successfully (I hope lol) changed the gasket (+ ESS gasket and valvetronic motor gasket) and reassembled the engine.

We did not start the car yet due to different opinion I heard about valvetronic calibration (i.e. just turn on ignition vs calibration with some software tool). I have e90 325i 2006.

I want to do the software calibration and I have INPA tool. Is it possible to do the calibration through INPA? I do not have it with me right now, I will only have it on a borrowed laptop in evening, and I just wanted to see beforehand how to do it instead of figuring it out when already connected to a car. I cannot seem to find any specific instruction from people except for them saying "just use some software for the calibration".

Is INPA enough or should be some other tool?

I have done many valve cover jobs on an E9x and never do the valvetronic procedure. It works itself out. You can do it with INPA, but it's a lot easier if you can get your hands on ISTA.

Somehow I managed to find the proper button (I hope? ) in INPA. I will try to get ISTA for the future. Anyway, after valve cover gasket DIY, for now at least, I see no leaks, and no errors from the car. Yes!
