Why is the engine fault light on in your Audi?
The engine fault light is a dashboard warning light that is part of your Audi Q4 E TRON car alert system . It illuminates to signal a potential issue with the engine.
But what exactly is an engine fault?
It can range from minor issues that don't prevent you from driving to more serious malfunctions that can affect engine performance or, in the worst case, cause irreversible damage.
What should you do if a warning light comes on in your Audi Q4 E TRON
If you encounter an engine fault or other issues (airbag, abs, esp, etc.), our advice would be to act cautiously and find out the root of the problem causing the light to illuminate. You can diagnose the fault with a diagnostic tool compatible with your Audi to learn more about this issue.
Based in Brittany, France, we specialise in electronic car diagnostics. We've been working on fault diagnostics and OBD diagnostic ports since 2009.
On-board electronics started appearing in vehicles in the early 2000s. It has since become essential to scan vehicle ECUs to retrieve engine fault information, particularly OBD2 fault codes. Our goal is to make these car scanners — usually reserved for professionals — accessible to private users, allowing them to identify faults and electronic error codes in their own vehicles.
With our klavkarr car scanners (100% Made in France) and our EOBD Facile software and mobile apps, we hope you'll be able to fix electronic issues yourself, without relying on your dealership’s diagnostic tool. Our solution is plug & play and very easy to use.
