Common problems & what to inspect

Based on 7 owner complaints filed with NHTSA for the 2018 Audi s4, here are the most-reported problem areas — and exactly what to check before you buy.

Engine 4 reports

🔍 Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.

Suspension 1 report

🔍 Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.

Service Brakes 1 report

🔍 Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.

Structure 1 report

🔍 Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.

Power Train 1 report

🔍 Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.

Vehicle Speed Control 1 report

🔍 Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.

Pre-purchase checklist

Match the VIN on the dash, door jamb and title — they must be identical.
Cold-start the engine; listen for knocks and check for blue or white exhaust smoke.
Test-drive through all gears at low and highway speed — no slipping, shudder or pulling.
Confirm every warning light clears at startup (none should stay on).
Check fluids — oil, coolant, transmission — for level, color and leaks.
Look underneath for rust, fresh undercoating or signs of collision repair.
Always get an independent pre-purchase inspection from a trusted mechanic.

Complaints filed with NHTSA by owners of the 2018 Audi s4.

ENGINE

Water pump defect for the 3.0L ea839 turbo engine found across many Porsche and Audi models. Defect causes damage to vacuum lines, thermostat, and can eventually lead to engine failure if not resolved. No way of knowing this is happening until you start to lose coolant (which will throw an engine code), but by that point the damage is done. There was a rec…

ENGINE

My 2018 Audi S4 has a catastrophic engine failure issue and this is common with the EA839 engine. There is a knocking in the motor that is caused by internal engine parts (rocker arms needle bearings) becoming loose and dislodged. The metal shavings travel in the motor oil and destroy the engine from the inside. Hendrick Audi northlake examined the car on Fe…

ENGINE

PCV housing and lines failed. Caused pressure to build up thus shooting off the oil cap shooting oil everywhere! in addition to that it is a huge fire hazard considering the turbo is right next to it.

SUSPENSION

Audi Dealer inspection revealed Rear spring is broken and mounts are deteriorating. Dealer states not common and would result in accident if not repaired. Research indicates broken springs common with certain Audi vehicles (A4/S4, Q5 & Q7), especially 2018 model year. See Audi World forum website. It would appear these springs are defective and will result…
