Irish buyers get the most car for their money in the B8 generation – the supercharged 3.0 TFSI is proven, and the facelift sorted early DSG headaches.

Five key facts every shopper should know before clicking “view listing”.

Bottom line: The Irish dealer market holds the bulk of S4 stock – but importing from the UK can unlock cheaper, better-specced examples for buyers willing to handle the paperwork.

What is the price range of a used Audi S4 in Ireland?

Five generations, five price brackets – here’s how they stack up from the cheapest high-miler to a low-kilometre facelift car.

Generation Typical price range (Ireland) Mileage range seen
B5 (1997–2001) €4,000–€10,000 150,000–250,000 km
B6/B7 (2003–2008) €6,000–€15,000 120,000–200,000 km
B8 (2009–2016) €11,950–€31,950 80,000–170,000 km
B9 (2017–present) €35,000–€50,000+ 40,000–100,000 km

The pattern: B8 dominates Irish ads, and within it the 2013–2016 facelift cars command a €3,000–5,000 premium over early examples.

Price by generation – real listings

  • A 2016 B8 S4 Quattro in Cork with 96,000 km was listed at €31,950 (DoneDeal (Irish classifieds)).
  • A 2009 B8 S4 with 111,044 km on Cars.ie was priced at €18,950 (Cars.ie (Irish car marketplace)).
  • A 3.0 TDI S4 Black Edition with 107,000 km was listed at €48,700 – a diesel rarity (Cars.ie (Irish car marketplace)).

Impact of mileage and condition

  • High-mileage B8 examples (over 140,000 km) can be found under €15,000, but expect pending maintenance (carbon cleaning, DSG service) (PistonHeads (performance car guides)).

Irish vs UK price differences

  • The Classic Valuer notes a median UK price of £12,426 (~€14,500) for the S4, while Irish ads average €18,450–€28,075 (The Classic Valuer (market database)).
  • After VRT (roughly 20–25% of UK price), a typical UK import still undercuts comparable Irish dealer stock by €2,000–4,000.
The catch

UK imports require a VRT payment, recalibration of speedo/odometer to km/h, and a NCT test – factor in at least €2,500 extra before you save anything.

What are the common problems with the Audi S4?

Engine issues

  • Carbon buildup on intake valves affects the B8’s direct-injection 3.0 TFSI – cleaning is recommended around 80,000 km and costs €500–€800 (PistonHeads (performance car guides)).
  • Timing chain rattle on cold start indicates stretched chains, a known issue on early B8 engines (Boards.ie (Irish motoring community)).

Transmission concerns

  • The DSG gearbox’s mechatronic unit can fail around 80,000–100,000 km – replacement costs €2,000–€3,000 (PistonHeads (performance car guides)).
  • DSG oil changes every 60,000 km are critical; missing them accelerates wear (PistonHeads (performance car guides)).

Suspension and drivetrain wear

  • Rear shock absorbers and control arm bushings are common wear items at 60,000–80,000 km (Boards.ie (Irish motoring community)).
  • Quattro system should not bind during tight low-speed turns – if it does, the centre differential or haldex coupling may be failing (PistonHeads (performance car guides)).
What to watch

An S4 with a full service history including DSG oil changes has a much lower risk of a €3,000 mechatronic surprise – skip any car without it.

Which Audi S4 model year is most reliable?

Four generations, four reliability profiles – pick the one that matches your budget and risk tolerance.

B5 (1997–2001)

  • 2.7 twin-turbo V6 is robust but age and rust are now limiting factors – subframes and rear arches are common corrosion points (Boards.ie (Irish motoring community)).
  • Best suited to enthusiasts willing to weld or replace panels.

B6/B7 (2003–2008)

  • The 4.2 V8 in B6 is thirsty and prone to chain guides failing – replacement is an engine-out job (PistonHeads (performance car guides)).
  • B7 introduced the 3.0 TFSI in later years; those are more reliable but rare in Ireland.

B8 (2009–2016)

  • Facelift models (2013–2016) are the sweet spot – improved chain tensioners, updated mechatronic unit, fewer carbon buildup reports (PistonHeads (performance car guides)).
  • Pre-facelift (2009–2012) cars should be checked carefully for DSG and chain issues.

B9 (2017–present)

  • Turbocharged 3.0 TFSI delivers 354 hp and better fuel economy, but repair costs are higher – an intake manifold can cost €1,500+ (Complete Car (Irish car reviews)).
  • Too early to judge long-term reliability; most Irish examples are still under 100,000 km.
Bottom line: B8 facelift (2013–2016) is the pragmatic pick – proven supercharged engine, addressed early flaws, and Irish supply is deep enough to find a good one.

Audi S4 vs Audi S5 vs Audi RS4: what is the difference?

Three models, one platform, but very different characters. Here’s how they stack up on specs, body styles, and running costs in Ireland.

Model Engine (B9) Power 0–100 km/h Body styles Typical price (Irish used market)
Audi S4 3.0 TFSI turbo V6 354 hp 4.7 s Saloon, Avant €35,000–€50,000
Audi S5 3.0 TFSI turbo V6 354 hp 4.7 s Coupe, Sportback, Cabriolet €38,000–€55,000
Audi RS4 2.9 TFSI twin-turbo V6 450 hp 4.1 s Avant only €65,000–€80,000

The trade-off: S4 and S5 share the same powertrain, but the S5 coupe sacrifices rear space for style. The RS4 Avant is faster and more exclusive but costs nearly double and insures accordingly.

Running costs comparison in Ireland

  • Insurance: S4 is group 38–40, S5 group 39–42, RS4 group 48–50 – expect a €500–1,000 annual premium difference between S4 and RS4 for a 30-year-old with full no-claims (Complete Car (Irish car reviews)).
  • Road tax: B9 S4 costs €750–€1,200 per year (depending on CO2 band); the RS4 sits in the highest band at €1,800+.
  • Fuel economy: S4 returns 7.5–8.5 L/100 km on a motorway run; RS4 is 9–11 L/100 km.
Why this matters

For a family buyer wanting daily pace without the insurance sting, the S4 saloon gives you the same engine as the S5 but with four proper doors – and saves you at least €3,000 compared with a similar S5.

How to inspect a used Audi S4 before buying?

Check the service history for two critical items

  • DSG oil change every 60,000 km – no stamp? Budget for an immediate service and mechatronic inspection (PistonHeads (performance car guides)).
  • Timing chain or belt service – B8s should have chain tensioner checked; B5/B6 require belt changes every 80,000 km (The Classic Valuer (market database)).

Listen for timing chain rattle on cold start

  • Start the engine cold – a diesel-like rattle that lasts 2–3 seconds indicates stretched timing chains, a €2,000+ repair (Boards.ie (Irish motoring community)).

Test all Quattro components

  • Accelerate hard from a standstill – the car should pull evenly without wheelspin or clunks.
  • Perform tight turns in a car park – binding or skipping from the rear suggests a failing haldex coupling (€1,200–€1,800 to fix) (PistonHeads (performance car guides)).

Check for rust on rear wheel arches and around sunroof

  • B5 and early B6 models are notorious for arch corrosion – poke the inner lip with a screwdriver; any soft metal means welding needed (Boards.ie (Irish motoring community)).

Carbon cleaning history

  • Ask if the intake valves have been cleaned – if the car has over 80,000 km and no record, budget €600–€800 for walnut blasting (PistonHeads (performance car guides)).

“A full service history with DSG oil changes is non-negotiable on a B8 S4. I’ve seen too many cars blow the mechatronic unit within weeks of purchase because the owner skipped the 60k service.”

– Irish mechanic quoted on Boards.ie (Irish motoring community)

“I had the carbon cleaning done at 80,000 km on my B8 and it felt like a different car – smoother idle, better throttle response, and almost 20 hp back. Do it before it causes misfires.”

– Owner on AudiSRS forum (enthusiast community)

Upsides

  • Quattro grip transforms wet Irish roads into secure driving
  • Strong tuning potential – B8 engines map to 430 hp reliably
  • Practical; saloon boot fits golf clubs and a buggy
  • B8 prices have fallen to accessible levels (€12k–€18k for a good one)
  • Approved Used programme by Audi Ireland includes 12-month warranty and 110-point check (Audi Ireland (manufacturer certified))

Downsides

  • Carbon cleaning and DSG repairs are expensive if neglected
  • High road tax (€750–€1,200 per year for B8/B9)
  • Insurance group 38+ puts off younger buyers
  • UK imports add VRT and compliance costs
  • B5/B6 rust is a real threat, especially in coastal regions
Bottom line: The implication for Irish buyers is clear: target a B8 facelift (2013–2016) with full history – that combination gives you the best balance of price, performance, and reliability.

For first-time S4 buyers in Ireland, the choice is clear
