I need to replace the bolt that goes through the bracket, and into lower part of intake manifold. fI know the size, I can probably purchase locally.

The crossover water pipe on the Wife's 2009 R55 was leaking where it enters the Waterpump. I watched a couple videos, and read some tutorials, but I couldn't remove the waterpipe with intake manifold in place. It was banging against the transmission linkage, and seemed very tight. I suspect the Non-turbo Intake must have a less space, because I used a lot of force and couldn't remove it. The lower bolt is really tight, and difficult to get off. I dropped it, and haven't been able to find it. I considered just leaving it off, but not sure if I can get away without it. I read on an online tutorial that its 9mm head, but I'm pretty sure I found a 10mm to be best fit.

Hoping someone here can help.

Thank in advance,
Lou

 

Your car is not turbo? Looks like it’s an m8x30, bolt #6, part number 07147543380:

Thank you! This is exactly the information I need. You are correct its "Non-Turbo" model.

 

I ordered m8-30 bolt and it didn’t fit. My car is m6-30 for bolt that goes into bracket

 

The bolt for my wife's R55 Non-turbo is M6-20. I looked up the parts on Real OEM, and bought replacement (M8-30) but it didn't fit. I might have mis-read the exploded diagram, but it pretty clearly looks like bolt #6 goes through the top hole of the bracket. I noticed that the bracket is easy to see with Intake Manifold removed. I took a picture, and made a mental note of the approximate distance from edge of valve cover, to bracket location. I originally started using an inspection mirror, but there are several wires that make it difficult to see with mirror. https://www.realoem.com/bmw/enUS/showparts...

 

Glad you got this sorted, mate. For reference, i typically get this type of metric hardware locally rather than ordering it with shipping.
