2021-2023 Audi Q5 e Fuel Tank Juddering TSB

Symptoms of Audi Q5 e Juddering

Owners of 2021-2023 Audi Q5 e vehicles may notice a distinct juddering sensation. This Audi Q5 e juddering typically occurs after moving off from a stop or specifically when the combustion engine engages. In some instances, even after software updates, a slight jolt might still be felt in certain accelerator pedal positions, which is attributed to the combustion engine switching on.

Diagnosis

When diagnosing the Audi Q5 e juddering complaint, technicians will first verify that the issue can be consistently reproduced. A key step in the diagnostic process involves checking the diaphragms on the fuel tank's non-return valve for any signs of damage. This visual inspection helps determine if the mechanical component is contributing to the juddering.

Repair Procedure Summary

Addressing the juddering condition involves a two-pronged approach as outlined in TSB 2077067/1. First, it is crucial to ensure the vehicle's software is updated to the current version specified in TSB 2071340, which relates to the condition "93 E-motor: Shuddering when charge level is low." This software update aims to optimize the e-motor's operation and reduce shuddering.

Following the software update, or if the juddering persists, technicians will physically inspect the non-return valve on the fuel tank. If the diaphragms are found to be damaged, the fuel hose containing the non-return valve must be replaced. The labor operations associated with this repair include removing and installing the fuel pump (operation code 2066 19XX), checking the fuel hose (non-return valve) (operation code 2037 0199), and replacing the fuel hose (non-return valve) (operation code 2037 5599).

Required Parts

The primary part that may need replacement to resolve the Audi Q5 e juddering is the non-return valve on the fuel tank. The specific part number for this component is 80A 201 741. Replacement parts should always be ordered for the individual vehicle using the Electronic Parts Catalog (ETKA).

Important Notes for Owners
