It’s a poor translation. It means traction as in “traction battery” not “traction control”.Weird! I'd probably do basic things like check tyre pressures are correct as that can upset traction control.
Usual 12v battery voltage check as that's a gremlin cause.
I think you can turn off the traction control. I'd try turning it off and driving the car a bit and then turn it back on and drive it some more. See if it's ok then or still grumpy. If you can't turn it off I'd disconnect the 12v battery positive lead for a minute and then reconnect, lock the car. Leave it for 10 minutes. Then unlock and see if it's still the same when you start it.
Using rapid chargers shouldn't cause this. If it does then PSA have dropped a massive clanger!
It’ll be the 12v. When was the last time you drove it?
