DIESEL TECHNIC manufactures this Manual Transmission Oil Seal DIESEL TECHNIC OE Ref 0189979147 to original equipment tolerances, which is why it's specified as a direct replacement for OEM 01019481B rather than a rough equivalent.
You'll find it referenced as 4.20734, EAN: 0405779526767 — worth noting down if you're getting a second opinion from a mechanic before fitting.
It's built for selected MERCEDES-BENZ vehicles. The safest way to confirm is matching OEM reference 01019481B against your existing part, or using our vehicle lookup tool with your registration.
