    HV replaced and now coolante heater failed

    Hi, one morning a few weeks back I came to my 2018 tesla model S and I had a bunch of errors on my screen and car wouldn't start and died in just a few minutes. I had a mobile technician come a couple of days later to change the 12v battery but he refused and said it was not the problem, so I...

    HV batterij probleem. Mijn model S85 viel volledig uit....

    Ik woon gedeeltelijk in Noorwegen en daar rijd ik een Noorse Tesla Model S P85D Heerlijke auto met 147K op de teller. Zelf daarvan 30K gereden vanaf het moment dat ik hem tweedehands kocht. In maart 2023 liep de HV Battery / aandrijfunits garantie af. Ik ben in Noorwegen voor de zekerheid even...

    HV replacement mileage ?

    Has anyone come across stats on the usual mileage for battery replacement on model 3s? A recent post got me wondering if that 1500 cycle figure is right (this person needs a replacement at 150k).

    BMS-029 - Tesla Must Do Better

    I am an early adopter of Tesla. I bought my Model S in Feb of 2015, laying out close to 90k for a car – which is something I would have never dreamed of doing previously. But I believed in the mission, I believed in the car – so I traded in my Kia Optima and subjected myself to this grand...

    HV Battery Pack Replacement

    I have a 2021 Model 3 SR+ without the LFP and I got the “BMS_a066” error message. From everything I’ve read, this indicates that the HV battery pack will most likely have to be replaced. I was wondering if LFP packs are used as replacements, or do they use the same type of pack that originally...

    Model 3 HV battery diagnostics cable and software

    Few weeks ago there was a link on Tesla Service to procedure, software and cable on how to read Model 3 (guess also Y) HV battery status directly from battery itself via low voltage communication port (one under read seat). Status was intended for 3rd parties who handled HV to know what they...
