Plug & Charge doesn't work on your Audi: the real reason (and it's usually not the car)

Plug & Charge is the feature Audi owners are most excited about and most disappointed by. The promise is simple: pull up to a compatible station, plug in, and the session starts and bills automatically. No app, no card, no QR code. When it works, it's the best charging experience on the market. When it doesn't, you're standing in the rain wondering why a 70,000 euro car can't talk to a charger.

The single most common reason a Plug & Charge session fails on an Audi isn't a hardware fault. It's a missing or expired contract in the myAudi app.

How Plug & Charge actually works

Plug & Charge is defined by the ISO 15118 standard. For a session to start automatically, four things must all be true at the same time:

1. The car supports ISO 15118 Plug & Charge. All current Audi BEVs (e-tron, Q4 e-tron, Q6/Q8 e-tron, e-tron GT) do, on the CCS Combo 2 inlet.
2. The charging station supports it. Not all do. Many CCS chargers still only support older OCPP authentication.
3. You have an active Plug & Charge contract linked in the myAudi app. This is the step that fails most often.
4. The car has a valid contract certificate stored on board. Certificates expire and occasionally get cleared by updates.

If any one of these four is missing, the car silently falls back to RFID, app, or contactless. You'll see no specific error. It just doesn't auto-start.

Step 1: check the contract, not the car

In the myAudi app:

1. Open the charging or e-tron Charging Service section.
2. Confirm a Plug & Charge contract (Audi e-tron Charging Service or a partner network) is active and not expired.
3. Confirm your payment method on file is still valid. An expired card silently disables Plug & Charge even when the contract appears active.

A huge share of "Plug & Charge stopped working" cases trace back to an expired card, a lapsed contract after a trial period, or a country mismatch when travelling.

Step 2: refresh the certificate on the car

If the contract is healthy and Plug & Charge still doesn't fire:

• In the car, go to Settings, then Charging, then Plug & Charge, and toggle it off.
• Lock the car, wait a couple of minutes, then unlock and re-enable Plug & Charge.
• Drive to a station you know supports Plug & Charge (the myAudi or e-tron route planner flags them) and plug in.

This forces the car to renegotiate and pull a fresh certificate.

Step 3: confirm the station supports it

If two known-supporting stations both fall back to manual authentication, the issue is on the car/contract side. If only one station fails, it's that station's back-end.

A note on AC and PHEVs

Plug & Charge is primarily a DC-fast-charging convenience. PHEVs (A3, Q3, Q5, Q7, Q8 TFSI e), which charge on Type 2 only, don't really benefit. For everyday AC charging, a reliable cable still matters more than fancy authentication, and a Voldt® Audi-compatible Type 2 charging cable handles the day-to-day home and destination sessions that Plug & Charge was never designed for.

Bottom line

Nine times out of ten, Plug & Charge fails because the contract or payment method in myAudi has lapsed, not because the car is broken. Check that first, then refresh the certificate, then try a different known-compatible station.
