Other Engine Info
Emissions Certification Test Group: KVGAJ03.0N7F; Federal/California Emissions Certification: Tier 3 BIN 70 LEV3 ULEV70
Problems:
1. dynamic brake support (dbs) issues
Dynamic Brake Support (DBS) systems, while high-tech, can sometimes malfunction due to sensor issues, software glitches, or wiring problems, leading to unintended braking or failure to activate when needed.
2. engine misfires
V-shaped engines, like the V6 in this Audi S4, can suffer from engine misfires due to faulty spark plugs, ignition coils, or fuel injectors, leading to rough idling and poor acceleration.
3. turbocharger trouble
The 2019 Audi S4's V6 engine is turbocharged, and turbocharger issues such as oil leaks, worn bearings, or boost pressure loss can result in reduced power and increased fuel consumption.
4. carbon buildup
Direct injection engines, like the one in this Audi S4, are prone to carbon buildup on intake valves, which can cause poor engine performance and reduced fuel efficiency.
5. emission system problems
The complex emissions systems needed to meet Tier 3 BIN 70 LEV3 ULEV70 standards can sometimes fail, leading to increased emissions, check engine lights, and the need for costly repairs.
6. timing chain wear
Audi V6 engines are known for timing chain issues, which can result in a rattling noise, poor engine performance, and potentially catastrophic engine damage if not addressed.
7. cooling system failures
The high-performance nature of the Audi S4's engine means that cooling system components like radiators, water pumps, and thermostats are under high stress and can fail, leading to overheating.
8. oil consumption
Some Audi V6 engines have been known to consume oil at higher rates than expected, which can lead to frequent top-offs and potential engine damage if oil levels are not maintained.
9. fuel system problems
Issues with the high-pressure fuel pump or fuel injectors can lead to poor engine performance, starting difficulties, and reduced fuel efficiency.
10. electrical problems
Modern vehicles like the 2019 Audi S4 have complex electrical systems that can suffer from issues such as faulty wiring, failing sensors, or software malfunctions, leading to a range of engine performance problems.
