Key Product Information
Additional Information
| SYMPTOMS | Common complaints that lead to 4E0-260-749-B being replaced: visible fluid seepage or drips, water intrusion into the cabin or trunk, wind noise at speed, oil residue collecting on surrounding components, or a fluid level that drops between services. Addressing the issue early usually keeps the repair contained to this component. |
| TROUBLESHOOTING | Isolating the fault around 4E0-260-749-B: clean the area completely and use dye or powder to confirm the actual leak source, since fluid migrates downward and the highest wet point is usually the origin. A scan tool with Audi specific coverage will show considerably more than a generic code reader. |
| INSTALLATION | Installing 4E0-260-749-B correctly requires clean, dry, undamaged sealing faces, the correct sealant only where specified, and even torque in sequence so the seal is not distorted. Torque values differ by model and production date, so consult the factory literature. |
| MAINTENANCE | Maintenance for this gasket and seal (4E0-260-749-B) is inspection based, checking for early seepage during routine service so a seal is replaced before it becomes a leak. Use fluids and parts that meet the Audi specification for the vehicle. |
| GENERAL_NOTES | Ordering note for 4E0-260-749-B: rubber seals harden with heat cycling and age, so a seal that has been disturbed should be replaced rather than reused even if it looks intact. Genuine Audi parts are built to the original specification, so fit, finish, and function match the factory component. |
| REPLACEMENTS | Related parts to order with 4E0-260-749-B: the surrounding gaskets, O-rings, and fasteners in the same joint are replaced together because the labor is shared. Confirm the related part numbers against the vehicle identification number. |
