Rear Motor Mechanical Seal (ATA250)

🔧 Fix the Most Common Audi e-tron Problem – Save Time, Money & Stress

If you own an Audi e-tron, you’ve probably encountered a well-known issue: leaking coolant seals and worn rotor bearings in the rear drive unit. These problems can lead to:

⚠️ Coolant intrusion into the motor
🔊 Increased drivetrain noise
📉 Reduced efficiency
💥 Complete motor failure if left unchecked

Instead of paying thousands at the dealership or waiting weeks for repairs, you can solve the problem yourself by replacing the coolant seal and upgrading the rotor bearing quickly and effectively.

IMPORTANT TIP for Optimal Performance of Mechanical Seals

1. Lubricate Seal Faces
Before operation, ensure that both faces of the mechanical seal are properly lubricated with coolant or technical-grade glycerine.

2. Purge Air from the Cooling System
Completely remove air from the cooling system using computer-assisted or vacuum methods. Air pockets near mechanical seals can cause premature damage!
