Macan MY26 Charging Problem: Car Sets Its Own Departure After IO Go Pause

[MMR]

I’m having trouble getting my MY26 Macan Turbo to charge properly overnight using Intelligent Octopus Go with an Andersen A3 wallbox.

I plug the car in with no departures or schedules set on either the Macan or the Andersen, so IO Go can take full control. It creates a charging plan without any issues (screenshot attached).

The car charges normally until the first pause in the IO Go schedule. As soon as there’s a break, the Macan seems to set its own departure time automatically, even though I haven’t asked it to. Then, when IO Go tries to restart charging for the next slot, the Macan won’t accept it—almost like it’s now following its own new schedule instead.

What’s even more frustrating is that when I go into the Porsche app to delete or switch off the auto-created departure, it doesn’t work—the app just says it can’t “send to the vehicle”, so the unwanted departure stays in place.

The Andersen A3 appears to be behaving exactly as expected, so it looks like the Macan is the one interfering.

Has anyone seen this before? And more importantly, is there a setting that stops the Macan from generating its own schedule whenever there’s a planned break in the charging?

IOG controlling the car is super buggy due to how there is no button to start charging in the app directly. Instead, they add a departure schedule about a week ahead to stop the car from charging, and then turn the schedule off when they want it to charge. However the porsche app connection is very spotty and it seems like IOG only attempts to control the schedule once. Then when it inevitably fails the car continues to charge not on schedule. Sometimes it works, but it fails more often than it works.

Fortunately, the A3 is much better when controlled by IOG. If you add the car again but this time select a different car that cannot be controlled by IOG (I chose Fisker Ocean) then it will default to controlling the A3 instead - much more robust in my experience so far.

For those of us with Andersen chargers they have now added compatibility with IOG. All chargers Including A2 from 2023->on.

I used to have IOG control the car instead of the charger, and as as we all know, it is super unreliable and will charge the car outside of the arranged off-peak slots.

You will need to remove the car from IOG and then add it is a new vehicle again. Note that if you select your Andersen charger and car as a Macan it will default to controlling the car instead of the charger. Not what we want. I got around this by choosing a car I knew could not be controlled by IOG, my previous car the Fisker Ocean! Then IOG logs into your Andersen account instead.

Andersen app shows this for the first time below. The charger now only releases power when it gets a slot from IOG, not the instant that the car is plugged in. Finally!

Have you tried Direct Charging?

It’s no help at all, but I’ve just turned smart charging off as IOG is so buggy with the Macan. Far too many occasions where it would be charging outside of the IOG schedule. All charging now done between 11.30 and 5.30

Direct charging won’t really help with Intelligent Octopus Go, because IOG only works if the car stays completely passive. If I switch the Macan to immediate/direct charging, it just pulls power at the full day rate, which defeats the whole purpose of IOG.

With IOG, the smart schedule gives me energy at roughly 30–40% of the normal cost. So if I bypass it and charge directly, the cost of a full charge jumps massively.

That’s why I’m trying to stop the Macan from creating its own departure after the first pause — I need the car to stay hands-off so IOG can actually deliver the cheaper energy.

Thanks — that’s really useful insight. I hadn’t realised IOG was basically “faking” a departure a week ahead and toggling it to control charging. That explains why it’s so unreliable with Porsche’s app connection.

If I switch the vehicle in IOG to something unsupported so it only controls the Andersen A3, is there any downside to doing that?

Will I still be able to see the Macan’s charge level and status in the Porsche app, or does that disappear once the “car” is changed?

I get why you’ve switched smart charging off — it definitely feels buggy with the Macan.

For me though, I don’t actually mind if it charges outside the 11:30–5:30 window, because IOG is supposed to give the night rate even during peak hours if the algorithm chooses to charge early.

For example, last night mine kicked in around 8pm, but it still counted at the lower IOG rate, so I’m happy with that as long as it works consistently.

I didn’t mean that sorry, when the car should be ‘paused’ according to the IOG schedule, it just doesn’t pause. So carries on charging into periods that will be at full rate. I’ve seen it happen too many times to have faith it in pausing when it’s meant to

Ah ok, I get what you mean now. That makes sense.

I’m having the opposite problem — when it hits the first pause, it turns into a permanent stop and never resumes. It’s happened both times I’ve tried charging with IOG so far.
