2021 Audi E Tron Sportback Recalls, Issues & Maintenance

The 2021 Audi E Tron Sportback carries 2 open NHTSA recalls — most recently covering camera and pedals and linkages. Owners report 6 recurring issue clusters, led by “High-voltage battery recall part unavailable.” 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.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Campaign #25V900000 · Dec 19, 2025

Issue: Volkswagen Group of America, Inc. (Audi) is recalling certain 2019-2026 vehicles. Please see the recall report for a complete list of models. A software error may prevent the rearview camera image from displaying as intended. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

Risk: A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.

Fix: Dealers will update the software, free of charge. Owner notification letters were mailed January 14, 2026. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 90TV. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on December 23, 2025.

SERVICE BRAKES, HYDRAULIC:PEDALS AND LINKAGES

Campaign #26V240000 · Apr 15, 2026

The fastener that connects the brake pedal and the brake booster may have been improperly assembled during manufacturing, which can cause the brake pedal to detach from the brake booster.

Risk: Brake pedal detachment can cause a loss of brake function and increase the risk of a crash.

Fix: Dealers will inspect and tighten the pushrod screw joint as necessary, free of charge. Owner notification letters were mailed on April 28, 2026. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 46P7. This recall expands previous NHTSA recall number 24V621.

Partial brake failure and brakes sticking to rotors

SERVICE BRAKES

2 NHTSA complaints · 2022-10 → 2025-01

On five separate occasions across two separate drivers, we have experienced a partial brake failure in this vehicle. We strongly believe this to be a software defect and not a mechanical fault
Owner report, NHTSA ODI #11639800
Car turns on but won’t move. Take it to dealership as it happens for the second time and turns out the brakes are sticking to the rotors. Audi says it’s perfectly normal just put force to the accelerator

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (Longlife Service)

Every 10,000 mi

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

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 10,000 mi

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.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 10,000 mi

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.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 24,000 mi

Replace DOT 4 brake fluid every 2 years regardless of mileage — Audi's published schedule is time-based because the fluid absorbs moisture.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

S tronic Dual-Clutch Fluid

Every 40,000 mi

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.

Estimated cost — typical U.S. ranges

Dealer

~$470–$640

Shop

~$330–$450

DIY

Pro only

VW/Audi DSG service needs a fluid-fill procedure at a specific temperature — shop equipment territory.

Important maintenance

Keeps your vehicle running smoothly and efficiently

quattro Coupling Fluid (Transverse Models)

Every 40,000 mi

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.

Spark Plugs

Every 40,000 mi

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

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Air Filter

Every 40,000 mi

Replace every 40,000 miles; inspect at 20,000 on turbocharged engines — a clogged filter shows up as sluggish boost response first.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Timing Chain (EA888 — Inspect Tensioner)

On condition / lifetime

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.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Pro only

Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Differential Fluid (Longitudinal quattro)

Every 60,000 mi

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.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Dust & Pollen Filter

Every 20,000 mi

Replace the cabin air filter every 20,000 miles or 2 years. Audi specifies an activated-carbon filter on most models.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

G12evo / G13 Coolant

On condition / lifetime

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.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

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.

How we estimate: Dealer = OEM parts × 1.4 + labor × $165/hr. Shop = parts + labor × $115/hr. DIY = parts only.
