Audi only charges properly on some charging networks

Audi only charges properly on some charging networks: what's really going on

If your Audi starts a session cleanly on one network and refuses on another, it feels random, but it usually isn't. The car is the same. The cable is the same. What changes between sites is the station hardware, the operator's backend, and the authentication method, and any of those three can quietly veto a session.

This applies to both Audi BEVs (e-tron, Q4 e-tron, Q6/Q8 e-tron, e-tron GT) on CCS Combo 2, and to PHEVs (A3, Q3, Q5, Q7, Q8 TFSI e) on Type 2 only.

Why some networks work and others don't

A charging session needs three things to agree: the car, the station, and the operator's account system. Common reasons one network fails while another works:

  • Firmware mismatch on older chargers that haven't kept up with current ISO 15118 / OCPP messages.
  • App or RFID authentication delays. If the operator's backend doesn't authorise quickly, the car gives up and the contactor opens.
  • Ground/earth sensitivity, especially on Q4 e-tron and other MEB-platform cars. Stations with marginal earthing show "Error in the charging infrastructure" while the car next to you on a different network charges fine.
  • Cable-locked stations. A tethered Type 2 cable on the station may be damaged, even if it looks fine, and your own cable would have worked.

How to narrow it down

  1. Keep a short note of which networks work and which don't, including the operator name and the station ID. After a handful of sessions a pattern usually emerges.
  2. Switch authentication. If you started the session in the operator's app, try the RFID card next time, or vice versa. A lot of "network won't charge me" reports are just app glitches.
  3. Try another bay on the same site. If a second post works, it's the individual charger, not the network.
  4. For untethered AC posts, bring your own cable. A known-good Voldt Audi-compatible Type 2 charging cable removes the station's tethered cable as a variable and often gets a session going where the built-in lead failed.
  5. Report the bad station through the operator's app. Most networks fix flagged chargers faster than people assume.

Bottom line

It's almost never the car. Log the failures, switch authentication, bring your own AC cable, and most "this network doesn't like my Audi" issues turn out to be one specific charger that needs servicing.
