Audi S4 recalls in Canada

Transport Canada runs its own recall programme. Its campaigns do not always mirror the American ones, so a Canadian owner reading a US-only list is reading about a different car than the one on their driveway.

2021 Audi S4 Recall 2022565 5 Oct 2022 19,006 units in Canada

Visual System

Issue: On certain vehicles, a software problem could cause the rearview camera image not to appear on the display.

2008 Audi S4 Recall 2018342 22 Jun 2018 19,649 units in Canada

Airbag

On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Dealers will replace the passenger frontal airbag inflator. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected. Additional Note: This recall supersedes recalls 2016-266 (Audi Recall 69O2), 2017-026 (Audi Recall 69P6) and 2018-022 (Audi Recall 69U1). Vehicles completed under the previous recalls require repair under this recall, as the previous recall remedy was an interim repair. Interim repair parts must be replaced with final repair parts.

These issues could increase the risk of injury. Correction: Dealers will replace the driver frontal airbag inflator. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected. Additional Note: For the Audi A4, S4, A5 and S5 models, this campaign only affects the Cabriolet versions of these models. Also to Note: This recall supersedes the Audi brand vehicles subject to recall 2016-064 (Audi Recall 69N1) and 2016-065 (69N2). Audi brand vehicles completed under the previous 2016-064 and 2016-065 recalls require repair under this recall, as the previous recall remedy was an interim repair. Interim repair parts must be replaced with final repair parts.

2008 Audi S4 Recall 2017026 13 Jan 2017 18,064 units in Canada

Airbag

On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Dealers will replace the passenger frontal airbag inflator. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected. Additional Note: This recall is superseded by recall 2018342 (Audi 69R7). <a href="http://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/detail.aspx?lang=eng&&rn=2018342">Click here for more information</a>.

2008 Audi S4 Recall 2016065 9 Feb 2016 15,039 units in Canada

Airbag

On certain vehicles, the driver frontal airbag inflator could produce excessive internal pressure during airbag deployment. Increased pressure may cause the inflator to rupture, which could allow fragments to be propelled toward vehicle occupants, increasing the risk of injury. This could also damage the airbag module, which could prevent proper deployment. Failure of the airbag to fully deploy during a crash (where deployment is warranted) could increase the risk of personal injury to the seat occupant. Correction: Dealers will replace the front driver airbag inflator. Note: This only affects the Cabriolet versions of the Audi A4 and S4 models.

2015 Audi S4 Recall 2014477 23 Oct 2014 15,116 units in Canada

Airbag

On certain vehicles, it is possible that the front airbags may not deploy in a crash as designed, due to an improper algorithm/coding within the airbag control module. Front seat occupants may not have the intended protection from the frontal airbag system in crash events where second stage deployment is warranted. This could increase the risk of injury to the front seat occupants. Correction: Dealers will adjust the airbag control unit deployment parameter.

1994 Audi S4 Recall 2000097 14 Apr 2000 565 units in Canada

Fuel System

On certain vehicles, a fuel feed line connecting the fuel filter to the engine can prematurely age and shrink through exposure to high under hood temperature caused by the turbocharger. Such shrinkage could cause a clamp connection adjacent to the turbocharger to loose its clamping force resulting in fuel seepage. Correction: Dealers will replace the entire fuel feed line from the filter to the engine with a fuel line of shrinkage-proof material.
