It's a well known issue that Mercedes made the power steering low pressure return line on the NCV3 and VS30 platforms juuuust a bit too short. When combined with the low clamping power of banded clamps, it's common for the hose to slip off or get dangerously close to it.

The Van Compass Power Steering Fix kit includes a small hose extension to alleviate this issue permanently and ensure that your van never suffers a loss of hydraulic pressure at an inopportune moment. This convenient kit includes everything you need to make a simple correction to a messy potential problem!
