Used Audi S4 B8: strengths, market context and inspection points

The S4 B8 combines 333 PS, quattro and understated everyday usability. Before comparing prices, establish saloon or Avant, pre-facelift or facelift, manual or S tronic, servicing, tyres, brakes and modifications.

This guide covers the Audi S4 B8 saloon or Avant with the 3.0 TFSI petrol engine on the German used-car market from 2009–2015. It excludes the S4 B9, RS4, diesel, cabriolet and heavily modified cars. Production phase, body, gearbox, modifications and VIN need to be confirmed for the individual vehicle.

Before the viewing, clarify these points: 1. Clarify stock condition, software, exhaust, and registrations. 2. Assess brakes, tyres, and quattro drivetrain with records. 3. Plan a specialist check for engine and drivetrain context.

If you already have one concrete listing, a Listing Audit can help sort the visible information, missing evidence, and next seller questions before you travel.

AUTO BILD describes the S4 B8 as a 333 PS 3.0 TFSI with quattro, offered as saloon and more commonly as Avant. Manuals were initially available; the report says this option ended with the model-year 2012 facelift. Registration date alone does not prove the production phase. These are model notes, not condition evidence or an in-house Vehilo road test.

FAQ snapshot on 5 September 2026: AutoScout24 reported 39 S4 B8 offers and one new listing in seven days. The median was €16,500 and the middle 50% €11,799–€19,999; dealers supplied 53% of adverts and 87% were automatic. Average mileage was 174,856 km.

Our market view: saloon and Avant, pre-facelift and facelift, manual and S tronic, and different modification states are mixed. These are adverts and asking prices, not completed sales, transaction prices or ownership transfers, not a valuation, and not a value, trend or resale forecast.

KBA reference 12491 with Audi code 69R7 (formerly 69EQ), Krit. 05, was published on 22 February 2023 for A4/S4/RS4 and other Audi models produced from 12 May 2003 to 29 September 2011. A faulty Takata gas generator in the passenger airbag can release metal fragments on deployment; the airbag module is replaced. The row lists 1,894,210 potentially affected parts/accessories worldwide and 545,012 in Germany, no known incidents and status ‘überwacht’ (monitored).

The row overlaps only early S4 B8 cars and names no VIN. ‘Monitored’ does not establish completion on an individual car, and the entry is not a complete S4 recall list. Check the VIN on Audi's official Takata/field-action page and request completion evidence.

The main inspection areas are: 1. Brakes, tyres, and suspension after hard use 2. quattro, differentials, and gearbox 3. Engine and cooling system depending on generation 4. Modifications, software, and road legality

Our view: AUTO BILD provides model and gearbox context, not evidence of current condition. AutoScout24 shows a small, high-mileage asking market, not sales. The KBA Takata row overlaps early B8 cars but replaces neither a VIN check nor a complete recall history.

Questions for the seller: 1. Which performance-related work is documented? 2. Has software or exhaust been changed? 3. Are all modifications registered? 4. Which tyres/brakes are fitted and when were they replaced?

Inspection priorities on site: 1. Check cold start, temperature behaviour, and fault memory. 2. Inspect brakes, tyres, and axles carefully. 3. Observe gearbox, quattro, and differentials under load. 4. Document underside and modifications.

Slow down when these signals appear: 1. Power is advertised while service stays vague. 2. Mismatched tyres or cheap brake parts. 3. Modifications without paperwork.

Is every manual S4 B8 a pre-facelift car?

AUTO BILD says the manual ended for model year 2012. Registration date alone still does not prove the production phase; vehicle data and features need to agree.

Are 39 offers sales figures?

No. They are visible advertised stock, not completed sales or ownership transfers.

Does KBA 12491 apply to every S4 B8?

No. The row covers several Audi models up to September 2011, but not an individual VIN. Audi's check resolves the specific car.

The evidence tiers separate authority or manufacturer sources from buyer guides and owner-reported patterns. Reddit, YouTube, and forums help discover questions for research, but they are not used as standalone proof for public defect claims.

This article is buyer guidance, not a technical diagnosis, workshop inspection, guarantee, legal advice, or proof that a specific car has a fault. Model notes are inspection prompts. A specific car still needs history, condition, recall status, and qualified inspection context.
