Audi Maintenance Service – Minor and Standard – What’s the Difference?

Audi Maintenance Service – Minor and Standard – What’s the Difference?

When it comes to Audi maintenance, there can be a lot of questions. Audi’s schedule on many of its late-model vehicles alternates from minor to standard every 10K miles or yearly depending on which comes first, and for vehicles in extreme service conditions, the recommendations can be even sooner. So, you can imagine how it can become confusing if you don’t keep track. But what’s the difference between these services, and how do you know what is really needed and what is just being done preemptively? 

We recommend oil changes every 6,000 miles to keep your engine in tip-top shape.

If you are looking for a short answer, Audi Minor and Standard Maintenance Service is nothing more than a glorified check and lubrication that often goes along with oil changes. Most recommended fluids and maintenance items are not part of these checks themselves. Those are typically recommended additionally at a certain mileage. Dealerships and most independent service shops are in the habit of wrapping this service all together at a set price, and this is done for simplicity, but also as a revenue generator. We feel this shotgun approach is disingenuous and does little to benefit the vehicle’s longevity or reliability. In the article below we will go over Audi’s service schedule and why we feel that Fluid MotorUnion in Naperville can do a better job maintaining your vehicle with less cost and more emphasis on keeping your vehicle on the road for years to come.

What are the two levels of Audi Maintenance?

Firstly, let’s go over what the minor maintenance service is. Minor maintenance is most importantly a check done after 10k miles usually done in tandem with an oil change, then alternately after the standard maintenance, or 20k miles or 2 years from the previous minor maintenance, whichever occurs first. The following are points of inspection during a minor service.


  • For diesel vehicles: the AdBlue fluid is filled completely with fresh fluid and adapts to learned values for the AdBlue tank under guided fault finding after filling fluid (All TDI models) 
  • The Brake system is checked for wear and leaks, as well as the thickness of brake surfaces and condition and level of brake fluid. 
  • The vent caps on the calipers are checked as well as the brake hoses
  • The cooling system for electrical e-tron vehicle’s coolant level is checked according to the description in ElsaPro 
  • Engine oil/oil filter is checked for it’s condition and is replaced with a new filter

What’s different about Fluid MotorUnion Audi Maintenance?

That’s why at Fluid MotorUnion, we do these checks as part of our digital inspections and recommend items a-la-cart. By taking extra time to inspect everything that a Minor and Standard Maintenance Service checks every time we ensure we are recommending only what your car needs when it needs it. This in turn allows us to better estimate what your vehicle will need next, and allows us to push potentially premature services to a time where you are getting the most life out of the component. Saving on things you don’t need urgently allows you to take better care of the major items that the vehicle might need, or if noted during our digital inspection, before failure ever occurs. Getting the most value out of your vehicle is important to us, and with our transparent digital inspection service, you know exactly where your vehicle stands.   

We only use high-quality fluids and parts
