Detailed Description

Bosch 1986AD1117 is an A/C compressor replacement for Audi models that require a 6SEU14C compressor with R134A refrigerant. The unit is oil filled and specified for PAG 46, helping simplify service preparation when replacing a worn or failed compressor. Its 6-groove pulley and 125 mm outside pulley diameter support OE-style belt alignment, while the 12-volt coil voltage matches the vehicle electrical system requirements.

For Audi A6 and Audi A6 Quattro service, as well as Audi A7 Quattro, Q5, S4, S5, and A5 Quattro applications, this Bosch compressor is built around OE dimensions to help maintain proper mounting and connector alignment. Part number 1986AD1117 is also a practical cross-reference for the same application when matching replacement options.

This part cross-references Bosch OE-style replacement numbers (e.g., 4F0260805AF, 4G0260805A) for the same application.

What It Helps Fix

• Weak or no cabin cooling from a failing compressor
• Compressor noise caused by internal wear
• Refrigerant circulation problems in the A/C system
• Belt drive issues related to compressor pulley wear
• Fitment problems when replacing an OE compressor with the wrong configuration

Installation Notes and Quality Assurance

Confirm refrigerant type, oil specification, pulley groove count, and connector alignment before installation. Replace the compressor only after the system is properly evacuated and inspected, and verify that the vehicle uses R134A with PAG 46 service requirements. Because this compressor is supplied without a seal ring, reuse or replacement of sealing components should be handled according to the vehicle service procedure.

Bosch subjects its A/C compressors to endurance, performance, vibration, leak, salt spray, and noise testing before release. That validation process supports OE-level fitment accuracy and durability for Audi HVAC repair.
