I have CHF 7.1. I wonder if that's the same as what you're recommending or if it can be used. This is what I have from my BMW. Oil cap removal it's no problem so I hope the AOS is not malfunctioning but I'm still curious as to why there's oil inside of it - there are two vacuum hoses that I need to find out where they come from. Noticed a little smoke at startup lately. Probably from the oil in the intake tube. The intake tube has no cracks or holes and all four clamps are holding well.
