The 2002 Audi allroad has no open NHTSA recalls. Owners report 8 recurring issue clusters, led by “Fuel tank and rollover valve leak.” Audi follows the VW Group Longlife service rhythm: oil and minor service every 10,000 miles or 12 months, whichever comes first, using oil that meets VW 502 00 / 504 00 (or 508 00 for newer 0W-20 engines) — generic synthetic does not qualify. S tronic dual-clutch gearboxes need fluid service every 40,000 miles despite 'lifetime fill' claims. Fully electric models (e-tron, e-tron GT) skip oil service entirely but keep brake-fluid, cabin-filter, and coolant-circuit intervals.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Critical for safety and preventing major damage
Replace oil and filter every 10,000 miles or 12 months with VW 502 00 / 504 00 / 508 00 spec oil. S and RS models driven hard: many owners shorten to 5,000-7,500 miles. Wrong-spec oil is the leading cause of TFSI timing-chain tensioner and PCV problems.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160

~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate every 10,000 miles with the oil service. quattro models: keep all four tires within 4/32" of each other — mismatched wear stresses the center differential.

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors, and wear sensors every 10,000 miles. Audi uses electronic pad-wear sensors on most models — replace the sensor with the pads.

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace DOT 4 brake fluid every 2 years regardless of mileage — Audi's published schedule is time-based because the fluid absorbs moisture.

~$180–$200

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
S tronic (DSG) gearboxes on A3/S3/RS 3, Q3, TT, and many A5/Q5 models: replace fluid and filter every 40,000 miles with the VW Group-spec fluid for your gearbox code. Skipping this service is the most common cause of mechatronic failure.

VW/Audi DSG service needs a fluid-fill procedure at a specific temperature — shop equipment territory.
Keeps your vehicle running smoothly and efficiently
A3/S3/RS 3, Q3, and TT use a Haldex-style rear coupling: replace its fluid roughly every 40,000 miles (some model years specify sooner — check your manual). Longitudinal quattro (A5-A8, Q5, Q8) has no coupling service; see differential fluid instead.
Estimated cost — typical U.S. ranges
Dealer
~$220–$290
Shop
~$155–$205
DIY
~$40–$90
VW/Audi/Volvo AWD coupling — specific fluid required. Filter usually swapped at the same time.
TFSI turbo engines: new plugs every 40,000 miles. RS models with the 2.5 TFSI five-cylinder: consider 30,000 miles under track or hard street use.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275

~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Replace every 40,000 miles; inspect at 20,000 on turbocharged engines — a clogged filter shows up as sluggish boost response first.

5-minute job on most cars; the airbox lid usually has clips, no tools needed.
2.0 TFSI (EA888) engines before roughly 2013 had timing-chain tensioner failures — have the tensioner revision checked by 80,000 miles on earlier cars. Later engines carry the updated design with no scheduled service.

Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.
Extends the life of your vehicle and improves comfort
Q5, Q8, and A5-A8 quattro: independent Audi specialists recommend front/rear differential fluid service around 60,000 miles even where Audi lists it as lifetime fill.

~$150–$195

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.
Replace the cabin air filter every 20,000 miles or 2 years. Audi specifies an activated-carbon filter on most models.

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Audi coolant is labeled lifetime fill. Independent VW/Audi specialists recommend a refresh around 5 years or 100,000 miles to protect the water pump and thermostat housing — and only with the correct pink/lilac VW Group coolant.

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Typical U.S. ranges. Actual quotes vary by shop, parts choice, and vehicle condition.
