Common Causes of a Flashing Audi Glow Plug Light:
The glow plug light on your Audi can start flashing due to several reasons. Here are some common causes:
Faulty Glow Plugs:
Audi’s diesel engines rely heavily on their glow plugs for optimal performance. Over time they can wear out and lead to:
- Difficulty starting the vehicle.
- Increased emissions.
- Poor engine performance.
|The car takes longer than usual to start
|High Emission Levels
|Excess smoke from exhaust indicates high emission levels
|Reduced Engine Performance
|Loss of power while accelerating
Fuel System Issues:
- Clogged Fuel Injectors: These prevent adequate fuel flow which results in poor engine performance.
- Malfunctioned Fuel Pump: This might not deliver enough fuel causing loss of power and hard starts.
- Dirty Fuel Filter: A dirty filter restricts proper flow of gasoline through it eventually affecting overall functioning.
Faulty Relay Module:
Finally, if there’s an issue with your car’s relay module (which controls how current is sent to various parts), this could result in a blinking warning sign too!
In conclusion, always pay immediate attention when you notice that pesky little light flickering! It’s definitely signaling something important about your Audi’s health!
