Type 25 Oil Dipstick Guide Bracket - 1986-92 - Waterboxer Engines

This replacement metal bracket secures the oil dipstick guide tube on 1900cc and 2100cc petrol Waterboxer engines fitted to Type 25 buses from August 1985 through to the end of production. It is a direct-fit replacement for the original factory support bracket and restores proper alignment and stability of the dipstick tube.

On Waterboxer engines, the dipstick guide tube must be held firmly in position to ensure accurate oil level readings and smooth dipstick operation. This bracket bolts to the engine and clamps or supports the guide tube, preventing vibration, movement, or fatigue cracking. Over time, the original bracket can rust, fracture, or go missing during engine work—allowing the tube to move, which can cause inaccurate readings, oil misting, or difficulty inserting the dipstick.

Replacing this bracket is a simple but important fix that helps keep the dipstick system working exactly as Volkswagen intended.

What this part does and how it works

The bracket anchors the dipstick guide tube to the engine, maintaining the correct routing and height of the tube. By holding the tube rigid, it ensures the dipstick follows the correct path into the sump every time, giving consistent and reliable oil level measurements while reducing wear at the tube’s base.
