Hello, I'd like to ask if there's anyone with any experience of retrofitting IBS system into their E90's . I've noticed that on OEM IBS from i.e. from factory the wiring harness for IBS is coming from behind the covers

random picture with IBS

as you can see there (I couldn't find better pic rn), but i've noticed that the wiring goes beneath the covers so i'm just thinking, if it's just tapping into the main harness which is that roll of cables, because i've been thinking about just tapping into them so that i could get an IBS working

Hello guys, I'd like to ask how can I remove stripped vacuum bolts on the engine head. The issue is that I was working on my car late at night and i've been changing some stuff and when i removed the head rocker cover which has another bolts going into those vacuum ones the vacuum ones just broke. So I bought new ones, but the issue is that I kinda messed up and used dull drill without any drill oil (I know, smart move 🫠..) so they are currently is bad state (more in photos)

as you can see one stripped vac bolt is in bad shape and I can't drill through it even with much better drill bits. I bought some with cobalt 12% i think and i tried it on the broken tip outside of the car and it went through easily, but it can't get through this since it cannot bite into it. Neither center punch works. The second hole of which i don't have photo is in the same state kind of, but i got the extractor in there and it broke.. So it's extremely "lucky" situation :).. I've been told on some forums to weld it, but i don't have welding machine, neither i know anyone. Maybe some car service could do it, but from what i heard there are some people that do these type of that, but they take a lot of money for it so yep.

I was thinking about buying dremel and using diamond heads to brush the hardened surface of and drill through that then, but I've got no idea if that would actually work or if it's even right stuff to do with it.

Any tips, experience would be really helpful. Thanks! <3
