There's an arrow on the rubber boot, should it face forward or face backward? i installed it back with arrow pointing forward, don't know if that's correct or incorrect.

Otherwise great DIY! Jacked the car up, got it on jack stand and everything worked. 1 word of caution is for my Canadian 07 328i, the circlip, etc is completely inaccessible from the interor. There's more metal blocking you than as shown in the photos of the original DIY. However tho things are still managable (both in removing circlip, removing gear selector, putting things back) underneath the car. Cheers!
