Removing and installing vane pump - Vehicles with 6-cyl. 5V engine — AUDI

🧭 Before you start

Clear the top cover and noise insulation, slacken the belt and lock the tensioner, clamp the hydraulic pipes and swing the ignition coil holder rearwards. Remove the pulley, disconnect suction and expansion hoses, unbolt the pump holder and take out holder and pump together. Refit the pump to the holder, tighten the two front bolts before the two rear ones, fit the banjo bolt on new seals and the suction hose to the P mark. After refitting the belt and coil holder, check fluid level, bleed the system and look for leaks.

Fits: platform code 4A

• Special tools named: 3094

Don't miss

• Mark belt running direction before removal; a used belt reversed could be destroyed.
• Tighten the holder bolts at the front first, then the two at the rear.
• Fit new seals to the pressure hose banjo bolt every time.
• Line the suction hose up with mark (P) at the pump end.
• Remove hose clamps 3094 before the system is filled and bled.
