OVERVIEW
Genuine VW/Audi flat washer, part number N-011-524-26. This original washer provides the specified bearing surface within its assigned fastening joint. The listed Audi applications use it in engine-cover, door-mirror or water-pump assembly hardware; the correct position depends on the vehicle and assembly.
Technical details
- Original part number: N-011-524-26 / N01152426.
- Flat circular washer with a central opening, supplied individually.
- Factory hardware assignment varies by assembly. Match the original washer and the complete fastening arrangement.
- Bolts, nuts, covers, mirrors and pump components are sold separately.
- This hardware washer is not a replacement for a separately specified coolant seal, gasket or O-ring.
Common reasons to replace
Replace a missing washer, a distorted bearing surface, damage around the center opening or corrosion that prevents the washer from seating correctly. Hardware may also need renewal when restoring an assembly that was previously fitted with an incorrect washer or missing parts.
Inspect the mating component and companion fastener as well. A fresh washer cannot repair a cracked cover, damaged mirror support, stripped thread or coolant leak from a separate seal. Identify the actual fault before replacing hardware.
Installation and service notes
Confirm the assigned location and factory hardware stack before disassembly. Keep track of any spacers, sleeves and companion washers, and inspect the bearing surfaces before refitting. Do not add extra washers to compensate for an incorrect bolt length or a damaged mounting point.
Seat the washer flat and start the fastener by hand. Follow the vehicle-specific tightening specification and service procedure for the assembly being repaired. Check alignment, secure mounting and the relevant component's operation afterward.
