^I didn't enjoy it either when I did my CCV job, took me about an hour just to get the O-ring seated properly and the new dipstick tube secured to bolt it in.
Replaced my brake light switch as my 2 year, intermittent ABS trifecta, even after rebuilding my ABS module, would still come around. Only code thrown was for brake light switch so it was replaced today, and I also cleaned and lubricated the clutch pedal spring as it was full of gunk when I was under the pedals working.
Also finished the install of the updated spring loaded hatch stoppers, very satisfied and no longer needing felt pads on the top hatch resting points. Rest of the weekend will be dedicated to running the angel eye harness for my Spyder headlights, and replacing the inner black door handle on the passenger door panel (peeling), if I'm really on a roll I will replace the regulator clips as well.
Picked up my E70 front wiper arms/blades as well from the dealer, small shortening of the passenger arm and I'll be able to lift my wiper arms without making them vertical when washing the X, and the updated wiper design will be a welcome addition as well
