2021-2024 Audi Instrument Cluster Warning Lights TSB

Audi has released Technical Service Bulletin (TSB) 90 23 19 2064789/3 to address a concern where various malfunction indicator LEDs in the instrument cluster may sporadically illuminate. This issue primarily affects 2021-2024 Audi A4, A5, S4, S5, and RS5 models equipped with an analog instrument cluster.

This TSB, which supersedes an earlier bulletin, Group 90 number 22-33 dated January 7, 2022, provides guidance for technicians on diagnosing and resolving the condition. Owners searching for information on Audi instrument cluster warning lights will find this document relevant.

Symptoms

Owners may observe that various malfunction indicator LEDs in the instrument cluster are sporadically lit. This typically occurs while driving with the Adaptive Cruise Control (ACC) system activated. Despite these warning lights, the vehicle's functions generally operate normally.

Diagnosis / Trigger Conditions

Upon inspection, workshops have found that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's modules when this condition is present. The technical background for this issue points to a deviation in the current draw of the LEDs specifically for the adaptive cruise control lamp. This deviation can cause other warning lamps to unintentionally illuminate.

Important Warnings

It is crucial to note that this Technical Service Bulletin does not apply if there are related DTCs stored in the vehicle or if the warning lamps are illuminated statically (i.e., not sporadically). In such cases, a different diagnostic approach would be necessary.
