A typical symptom of the valve failure is erractic movement of the roll bar/rear head rests. Typically, the head rests will not stay down. This is usually accompanied by loss of hydraulic fluid, but the leaks can remain internal.

The valve is located behind the rear seat, in the left rear corner, bolted to the roll bar assembly. It has several hydraulic lines attached, which are easily removed.

Valve removal: 8-mm wrench or pliers/vise grips to remove the supply line on the side, 4-mm hex wrench (Allen) to loosen the bolts that hold the retaining disc for the hydraulic lines in the front, 10-mm wrench for the bolts in the rear that mount the valve to the roll bar assembly.

There are two versions of this valve - see photos. Newer versions used in 2001+ models have the number 19.0306-0106.2 engraved on them.

Optional core exchange includes an additional $30 charge, plus a refundable deposit of $200.
