"burnt valves" aren't a thing. They overheat because they can't be properly cooled, then they fracture.

It would be difficult for customers to know what to do if their owner's manual says one thing and the Internet says another thing. Ignore the manufacturer's recommendation out of fear of having the warranty voided or follow what people say online out of fear of having the engine destroyed? What would you do?
What Audi says for this engine in the owner's manual is below.

Burned valves are definitely a thing. A burnt valve is just a valve that has been damaged by excessive temperatures. The heat causes the edges of the valve to literally burn away. In some cases, the valve may experience thermal shock, causing a portion of the valve to crack or break off which you are referring to.
Temperatures in the combustion chamber can far exceed what you are referring to and are definitely hot enough to burn a valve.

You guys were discussing oil brands earlier and I was surprised nobody mentioned using Castrol. The oil filler cap on my 2018 A6 3.0T and my daughter's 2018 Tiguan both have "Castrol" printed on them. I've been using Castrol Edge 5W40 in them since new without consumption issues, at 63,000 and 70,000 miles. Is "Castrol" printed on your filler caps too?
Btw, because of this thread, I've started using a bottle of Techron in the gas & am planning to add a bottle to the gas with each oil change from now on.

So far, so good. Occasionally would add Techtron - every 4-5 months or so. So far, so good.

FCPEuro. You ship your old oil and they refund you. Lifetime warranty. Changed the oil on my Q5 last weekend and sent the oil back yesterday - 25$ oil change.

I purchased my 2017 Audi Q7 in August 2016. The vehicle is advertised as requiring servicing and oil change every 10,000 miles. Unfortunately, my vehicle has never made it to a 10,000 mile interval without the yellow oil indicator light come on. When I asked the Audi service agent , he states that the car does not typically make it to a 10,000 mile interval because of the large engine. Over the past 5 years the interval to add one quart of oil has been less and less. It has gone from ~9500, 7500, 3000 intervals. On July 22, 2021 I took my car in for the 80,000 mile service. The actual mileage on the odometer was 80,304. The car service was complete and returned. On August 16, 2021, my yellow oil indicator light came on at 81,588 miles. I called the my local Audi Service and was advised to come in for an oil consumption test. I also notified the National Audi Customer Service line to voice my concern for my car. I inquired if oil consumption is a known issue in the Audi Q7 2017. There was not a clear admission of this concern in their vehicles but it made me concern that this could be an issue because of historical issues with Audi's early consumption of oil. I am concerned because this vehicle has the oil indicator light come on in shorter intervals which make me concerned about the longevity and reliability of the engine.
I had the same issue and it only gets worse. Mine started leaking oil periodically. Has anyone had the same issue and actually got to the bottom of it?
