Audi only starts charging after reconnecting: why the second plug-in works

It's a common Audi quirk: you plug in, nothing happens, you unplug, plug back in, and now the session starts normally. Annoying, but rarely a real fault. In almost every case it's a handshake that didn't complete on the first attempt, and the reconnect simply forces a clean retry.

This behaviour affects both Audi BEVs on CCS Combo 2 and PHEVs on Type 2.

What's actually happening

When you plug in, the car and the charger run a short conversation: proximity detect, control pilot signalling, power negotiation, authentication if the station needs it, then contactor close. If any one of those steps times out or returns a noisy signal, the session never starts. Pulling the plug and reinserting it resets the conversation from step one.

The usual triggers:

• Plug not fully seated. Audi sockets need a firm final push. "Looks in" isn't the same as "is in".
• Dirty or oxidised contacts on either the car inlet or the cable.
• Slow backend authentication, where the station gives up before your account is authorised.
• A marginal cable with intermittent pilot or proximity continuity, especially common with worn or cheap aftermarket Type 2 leads.
• Stale charging schedule in the car that blocks the first attempt at a non-scheduled time.

How to fix it for good

1. Push the plug in firmly until you hear or feel the latch click. Many "won't start" cases die here.
2. Inspect both ends of the cable for bent pins, debris, or green oxidation. Wipe clean if needed.
3. Disable any active charging timer before testing, so the car isn't refusing the session because it's outside the scheduled window.
4. Try a different station to confirm the behaviour follows the car, not the post.
5. Swap the cable for a known-good one. A pilot-wire issue is impossible to spot visually. Replacing the lead with a Voldt Audi-compatible Type 2 charging cable eliminates the cable as a suspect in one step.
6. If the issue persists across cables and stations, book a software check at an Audi service centre. A myAudi firmware update has resolved this for a number of owners.

Bottom line

The reconnect trick works because it forces a clean handshake. Seat the plug properly, clear schedules, swap cables to rule one out, and the first plug-in should start the session every time.
