OVERVIEW
Genuine VW/Audi lower air conditioning mounting adapter
8K0-260-753-B is the individual lower adapter used in the assigned air-conditioning mounting arrangement. It is listed separately from the corresponding bracket and upper intermediate piece.
The supplied component is the bare lower mounting adapter. Select the required bracket, upper piece and fasteners separately for the original assembly being repaired.
Technical details and supplied quantity
- Manufacturer part number: 8K0-260-753-B; compact reference 8K0260753B.
- Brand: Genuine VW/Audi.
- Component: lower air-conditioning mounting adapter.
- Position: lower adapter location in the assigned original support arrangement.
- Quantity: one individual adapter per purchase.
The relevant factory catalogs distinguish this lower adapter from the upper intermediate piece. They also identify production changes on the earlier A4, A5 and Q5 arrangements. Match the original part and build date rather than treating the earlier unsuffixed adapter as interchangeable.
Common reasons to replace
- The original adapter is missing after assembly work.
- The mounting profile is split, distorted or otherwise damaged.
- The adapter no longer seats correctly in the specified support arrangement.
- Repair of the affected mount requires its separately specified lower component.
Inspect the bracket, mating component and fasteners before fitting the replacement. A damaged receiving mount needs its own repair. An A/C cooling fault or refrigerant leak requires diagnosis of the actual circuit fault; this mounting component does not replace a pressure line, seal or compressor.

Installation and service guidance
Follow the factory procedure for access to the assigned mounting location. Record the orientation of the lower adapter, upper piece and bracket before disassembly. Compare the mounting profile with the replacement and inspect the surrounding components for damage.
Fit the adapter in its prescribed lower position using the correct separately specified parts and attachment hardware. Follow the factory tightening and assembly sequence. Do not force an incompatible support profile into place or use the bolts to correct a distorted mount.
If the repair requires opening the refrigerant circuit, follow the applicable recovery and service procedure. Restore all disturbed supports and inspect the repaired arrangement for secure seating and correct clearance before completing the work.
