I went this route ( https://www.germanautosolutions.com/...12_bar_cap.php )

Then i realized after you can just get one from the parts counter at BMW or order it online. they all state the pressure on them. I think the BMW one is 1.4 bar now.

I have been running the GAS one for years without any issues. I add about a cup of blue bmw coolant per year.

I wonder why the "application list" only lists the 3.0i motor for e53?
