Why does the check engine light in my 4000 turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your 4000 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 4000 making engine noise?

Unusual noises can signal a problem with your Audi 4000 engine. Tapping or knocking could mean you need an oil change. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Audi 4000 engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving the engine while still 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.

Can I add water to my Audi 4000 radiator?

What can cause the engine in my 4000 to suddenly stop?
