2010-2026 Audi A/C Compressor Replacement Test Plan

Audi has issued Technical Service Bulletin (TSB) 2041717/13 to clarify the mandatory procedure for replacing an A/C compressor in 2010-2026 Audi models. This bulletin emphasizes that a specific ODIS GFF cooling performance test plan must be performed before any A/C compressor replacement. This ensures proper diagnosis and documentation of the repair.

This TSB applies to any repair that involves replacing the air conditioning compressor. It was last revised as Revision 13, with previous revisions on December 17, 2024 (Revision 12) and September 20, 2024 (Revision 11), which removed a reference to TSB 2035582.

Symptoms

Owners may experience various issues related to the air conditioning system, including:

• "climate control -> operation, climate control -> A/C system switch" with a complaint type of "functionality -> too difficult to move"
• "climate control -> heating, cooling -> climate control unit cooling output -> A/C compressor activation\deactivation" with a complaint type of "functionality -> no function"
• "climate control -> heating, cooling -> climate control unit cooling output -> A/C compressor control" with a complaint type of "functionality -> no function"
• A customer complaint that the "air conditioning cooling is insufficient"
• For vehicles with an HV compressor, a "MIL and / or electrical error is displayed in the instrument cluster" where the system "does not cool"

Diagnosis and Repair Procedure Summary

Before replacing the A/C compressor, technicians must run the ODIS GFF cooling performance test plan. This test plan is crucial for verifying the compressor's functionality and documenting the repair process. The exact navigation path for this test plan within the ODIS system can vary depending on the vehicle model and equipment level.

Here are the general navigation examples for accessing the test plan:

• Vehicles with 08 – Heating and Air Conditioning Electronics: Navigate to the Guided Functions tab, then select 08 – Front A/C display control head –E87- >> 08 Heating/Air Conditioning Electronics, functions >> 08-Other Functions. Alternatively, from the Test plan tab, select Body >> Heating / Air Conditioning >> 01 – On Board Diagnostic (OBD) capable systems >> 08 Climatronic control module, functions J255 >> 08-General function tests.
• BEV Vehicles with C5 – Thermal Management Control Module: Navigate to Diagnostic capable system >> 00C5 - Thermal Management Control Module -J1024- >> 00C5 - Thermal management control module, functions >> System function test >> Interior cooling. Another path is Diagnostic capable system >> 00C5 - Thermal Management Control Module -J1024- >> 00C5 – Basic Settings Complete >> Basic Setting Selection >> System function test >> Interior cooling.
• PHEV Vehicles with C5 - Thermal Management Control Module: Navigate to Body >> Heating / Air Conditioning >> 01 - On Board Diagnostic (OBD) capable systems >> 00C5 - Thermal Management Control Module -J1024- >> 00C5 – Thermal management control module, functions >> System function test >> Interior cooling.
• Vehicles with HVAC control in 09-Vehicle Electrical System Control Module: Navigate to Body >> Electrical Equipment >> 01-On Board Diagnostic (OBD) capable systems >> 09-Vehicle Electrical System Control Module J519 >> 09-Electric Central Electric, functions >> 09-Other functions, Air Conditioning test plan.
