Hello, I have a problem with my friends mercedes eqa300. It seems that the vehicle does not accept my ChargeParameterDiscoveryRes message. It just does not answer anymore. Does anyone have some suggestions what the problem might be? The PCAP is in the appendix.

Hmm...it does not check during pre-charge, but instead does this during charging.
Can you post the pcap file for your new test?

Ok I have already tried the scenario with 2 amps in the response but no difference. And if I actually follow the requested values from the car both timeout pretty quick after about 20 seconds.

Hi, I also face the problem of timeout on two different cars. VW ID.4 times out after exactly one minute and the BMW IX4 times out after 5 minutes. Is there any way to reset the timeout so that the car keeps the switches closed? PS - I'm responing with the exact voltage on the DC pins and zero amps ...
