On the 1994-1998 Audi Cabriolet, the power convertible top uses a hydraulic system with pump, cylinders, and hoses that develop leaks with age. The top can become stuck in the up or down position when the system loses fluid or the pump fails.

Common Symptoms

  • Top not operating
  • Slow top movement
  • Hydraulic fluid leak
  • Top stuck partially open

How to Fix

Inspect the convertible top hydraulic system by checking the pump reservoir fluid level, looking for ATF/hydraulic fluid leaks at the pump, lines, and lift cylinders behind the interior trim, and verifying pump power/ground before condemning the motor. Leaking cylinders or cracked hoses should be replaced or professionally rebuilt as a pair, then the system refilled with the correct hydraulic fluid and cycled/bled to remove air; if the pump runs weakly or not at all, replace the pump assembly and inspect the top frame/linkages for binding. Typical repair costs range from about $300-$700 for hose or single-cylinder repairs, $800-$1,500 for both cylinders and fluid service, and $1,000-$2,000+ if the hydraulic pump assembly also needs replacement.

Typical repair cost:$500 - $2,500
