Hi Guys,
Here are my 11mm tools that I plan to tackle the CDV job! I am 99% sure the bleed nipple is a 11mm. Every BMW in the past used this size. Sometimes they use a smaller 7mm on the brake calipers for the rear axle. Most of my tools are Hazet since they are high quality and not too expensive over here. I paid 23 euros for these three tools. The bottom long 11mm wrench is a Gedore - an Hazet sub-line I think. Made in the same zip code! Any excuse for me to buy new tools is good!
11mm wrenches
Hose clamp - to prevent brake resivor from draining out!
And every tool box should have wrenches like this:
when working on brake lines - a flare wrench like this will not strip or round the corners of the brake line nuts. or... when ever possible use a 12point box(ring) wrench.
Next week when I change my oil, I will replace the CDV too. I'll see which wrench fits!
