Signs You Need a Replacement
If your equipment is showing any of these symptoms, the injectors & nozzle may be the cause:
- Rough idle or misfire — Uneven fuel delivery from a worn injector causes the engine to shake at idle. On engines, this is often accompanied by a knocking sound under load.
- Black or white exhaust smoke — Black smoke means excess fuel; white smoke indicates incomplete combustion. Both point to injector spray pattern degradation.
- Loss of engine power — A single failing injector reduces cylinder output. Multi-cylinder engines lose noticeable power when one injector flows less than the rest.
- Increased fuel consumption — Poor atomization means the engine burns more fuel to produce the same power. Monitor your fuel burn rate as an early warning sign.
- Hard starting or no start — If the injector doesn’t deliver fuel on cranking, the cylinder won’t fire. This is especially common in cold weather with worn nozzles.
- Fuel in engine oil (dilution) — Fuel leaking past the injector seat seal contaminates the crankcase oil. If the oil level rises or smells of diesel, inspect the injectors immediately.
Replace as a Set
Replace all injectors as a set whenever possible. On engines, mixing old and new injectors creates uneven fuel delivery — the new injectors compensate for the worn ones, shortening their life. When installing, use new copper sealing washers and torque to the specification in the service manual. After installation, run the engine at idle for 5 minutes to bleed air from the fuel system, then check for leaks at each injector connection before putting the machine under load.
Frequently Asked Questions
Which Audi models does this part fit?
Refer to the Vehicle Compatibility table above for the full list of Audi models. Each listing includes the body type, engine, and production years. Match your vehicle’s engine code (stamped on the engine block) against the listed codes to confirm.
Can I cross-reference 0280158117 with Application?
Yes. Both 0280158117 and Application are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.
This listing is for 4 pieces – do I need to buy a full set?
This listing includes 4 units. For best results, replace all injectors at the same time rather than one at a time. Mixing old and new units causes uneven fuel delivery and shortens the life of the new parts.
My vehicle is a 1999 model – is it covered?
The compatibility range for this part includes 1999-2006. The 1999 model year falls within this range, but verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.
