Why does my Q4 e-tron’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your Q4 e-tron testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my Audi Q4 e-tron making engine noise?

Strange under-the-hood noises can point to problems within your Audi Q4 e-tron engine. Knocking or tapping could be a symptom of low oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing may be caused by a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Audi Q4 e-tron engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving your engine while the vehicle is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Is it okay to put water in my Audi Q4 e-tron radiator?

It’s not recommended you put water in your Q4 e-tron radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What can cause the engine in my Q4 e-tron to suddenly stop?

Reasons your Q4 e-tron car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
