When should Audi A8 Quattro spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Audi’s recommendations.

What do I do if I see a pool of liquid under my Audi A8 Quattro?

Don't ignore puddles of fluid under your Audi A8 Quattro. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

What do hard starts and stops do to my A8 Quattro engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
