What is S tronic, and why does it matter?
S tronic is Audi's name for its direct-shift gearbox, a two-clutch design that changes gear quickly with no torque converter. Volkswagen calls its version DSG, and the idea is the same.
A gearbox like this runs on specialist fluid that needs changing, so ask where that falls in your Audi's schedule, and don't let it become something nobody checked. If yours jerks at low speed, hesitates pulling away or shows a gearbox warning, go to someone who knows these units. A transmission check is the place to start.
Quattro isn't one system
Quattro is the trademark Audi puts on its all-wheel drive cars, and the hardware under it changes with the model and the era. An A3 quattro, with its engine across the car, uses a clutch-based setup. Cars with the engine sitting lengthways use a different centre differential, and the Q7 has its own again.
So "it's a quattro" isn't enough to go on. When you tell us the job, give the model and the year. Ask which system your car has and what fluids it calls for. A mechanic who works on Audis regularly should be able to tell you.
Does an A3 need the same care as a Q7?
The schedule idea is the same, but the size of the job isn't. A big SUV like a Q7 works its brakes, tyres and suspension harder, while an A3 used for city trips can see its 12-month limit long before 15,000 km.
S and RS models ask more of everything. If yours is one, mention it, because brakes, tyres and fluids on a performance car aren't always the same as the standard model's. CarsGuide reported in 2022 that e-tron cars came with a six-year servicing plan, so check what's left on yours before you go elsewhere.
Your Audi warranty and roadside cover
New Audis delivered to private customers from 1 January 2022 have a five-year, unlimited-kilometre warranty, and that includes S, RS and e-tron cars.
Going to a qualified independent mechanic who follows Audi's schedule and specifications doesn't by itself void it. The thing that can lapse is roadside help: Audi Roadside Assist is reactivated each year after scheduled servicing at an Audi dealership service centre. If you step away from the dealer, line up roadside cover elsewhere.
Good questions for an Audi mechanic
- How often do you work on S tronic gearboxes, and do you do the fluid changes yourselves?
- Which quattro system does my car have, and what does it need at this service?
- Can you read Audi fault codes and reset the service reminder?
- Which oil specification does Audi list for this engine?
Finding the right mechanic
Look for someone who sees Audi and other European cars every day, not once in a while. Our European car service page explains what to expect.
Under a national scheme covering vehicles made from 2002 onwards, repair information that dealers use is available for independents to buy. Whether a particular workshop subscribes is another matter, so raise it. A local mechanic who specialises in your car.
What an owner can look after
You can
- Find the next service date in your service record or on the dash.
- Note when a gearbox jerk or warning shows up, and whether the car was cold.
- Keep tyre pressures right and all four tyres in good shape.
Leave to the mechanic
- S tronic fluid changes and anything inside the gearbox.
- Quattro diffs, couplings and their fluids.
- Fault codes, and high-voltage work on an e-tron.
What we'd do with an Audi
We'd find out exactly which gearbox and quattro system the car has, then look for a mechanic who works on that hardware often. We'd want a written estimate that names the oil specification, any gearbox or drive fluids due, and the service reminder reset. If the car's still under warranty, we'd keep the invoices and sort roadside cover before leaving the dealer.
