This line goes from the valve block on the left side to the right main drive cylinder. It is a common failure in E46 convertibles. If you buy OEM part number 54347025598 for more money from the dealer, you will likely get the same problem again. Top Hydraulics ships an EXTENDED LINE.

Please see the detailed DIY guide for line replacement in our DIY section - it shows you how you can save a lot of time in replacing this hose, plus install a product that is far less likely to break again.

Lines 23 and 24 go from the valve block (aka solenoid block or hydraulic unit) to the right main lift cylinder, and they are routed close to each other. Each is secured to the valve block by a retaining disc. Line 23 connects to the upper retaining disc, and line 24 connects to the lower one. The retaining discs have numbers engraved on them that match the hydraulic lines they are holding in place.
