Day 8, bolt still remains 😭 As I uploaded the photos from the phone I couldn’t mark the bolt in the photo, but it’s the only one visible.

There doesn’t seem to be any cover over the rack to allow more access.

I’m seriously considering getting the angle grinder out and cutting into the car to gain access.

The DR Seuss tool looks amazing!

The links to the other tools are appreciated, the third one won’t work, but the first looked possibly plausible.

I had to give it up for a while yesterday for my sanity. I’m now looking at bending and chopping some of my existing tools to get to the bolt.

I’m fairly certain BMW techs must have a specific tool to undo this bolt on RHD models, it has to be ratcheting and deep.

I have a picture of the replacement compressor that I will upload so you can gauge the depth and bolt position from the rear.

Thank you everyone for your suggestions
