2021-2026 Audi Collapsible Spare Wheel Inflation TSB

Owners of various 2021-2026 Audi models may notice that their collapsible spare wheel does not appear to inflate fully when using the compressor from the vehicle's tool kit. This can lead to concerns that the tire is not properly pressurized or safe for use. Audi has issued Technical Service Bulletin (TSB) 44 23 02 2065160/2 to address this common customer observation.

Symptoms

Owners typically report the following symptom:

• "The temporary/collapsible spare wheel does not inflate fully when it is filled using the compressor from the breakdown set. The pressure specified on the collapsible spare wheel is not reached using the compressor."

Despite using the compressor and following instructions, the Audi collapsible spare wheel inflation may look incomplete, giving the impression that the tire is still underinflated.

Technical Background

Audi's TSB clarifies the technical reason behind this appearance. The collapsible spare wheel is designed to be used when the tire tread is aligned horizontally with the hub. When this alignment is achieved, the sidewall of the collapsible spare wheel may not align perfectly symmetrically with the rim.

This asymmetrical alignment creates the visual effect of the tire not being fully inflated. However, the compressor is designed to reach a pressure of 3.5 bar (approximately 50.7 psi) after running for a certain period. This pressure is sufficient for safely using the tire.

What Owners Should Know

It's important for owners to understand that the perceived underinflation of the Audi collapsible spare wheel inflation is a visual characteristic and not an actual defect. The TSB confirms that the tire, when inflated to 3.5 bar by the vehicle's compressor, is in suitable condition for use.

This bulletin is informational and does not require any repair procedure or parts replacement. It serves to inform technicians and owners that the tire's appearance is normal and does not indicate a fault with the spare wheel or the compressor.

Important Warnings

This TSB is informational only and is not applicable to any Audi Warranty. This means that if you take your vehicle to a dealership solely for this concern, it may not be covered under warranty as there is no defect to repair.
