Why does the check engine light come on when I start my A6 allroad?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your A6 allroad firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Why is my Audi A6 allroad making engine noise?

Strange engine sounds can be a sign something’s off in your Audi A6 allroad. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Audi A6 allroad engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I use water in my Audi A6 allroad radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

What could cause my A6 allroad engine to suddenly stop?

Your A6 allroad car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
