So F25 with a common rail tuning chip is a no go.

At which point did you give up? I got to the stage where I couldn't remove the common-rail plug, but I'm not sure if I was doing it right or not. The sun was starting to go down so I abandoned it and clipped everything back together. I didn't need any special tools to remove any of the parts. It can be a bit unnerving pulling off things like the engine acoustics cover and the filter cartridge, but they do come off with a bit of force. It's just that damn connector at the front of the common-rail. I started to think BMW glued it in place but surely they couldn't do that for servicing reasons.
