VW TECHNICIAN said: Most parts stores have tools to check 12V battery under load for SOH. The trick to this is they need to disconnect the 12v for this test, or else it will be getting up to 200A charge from the DC - DC converter (even if they think the car is 'off') CO Early Adopter - Solar PV and EVs since 1987.

Test the 12v. Also turn on the battery care, that maintains the 12v battery. If the car has sat around that long the 12v could be the issue. Yes, the Care is in the infotainment screens/system. 👍. Testing the 12v is old school, a volt meter to check where it's at. 12.6V is a perfect car battery. 12.2 is ok.

In rear-wheel-drive models of the ID.4, VW says the 12V battery's charging cable can rub against the steering column, potentially resulting in a short-circuit if the insulation becomes worn. If

There's no setting you missed, that's how it's wired. It's pretty common in German cars to not have the accessory ports powered with the key off. It prevents accidental battery drain. How do you power the 12v outlet in the back? Is It only powered when the car is on? I guess I missed a setting somewhere but I can't figure it out.

VW roadside assistance sent a tow truck the following morning, the driver rolled it out of my corner garage and took it to the dealership. When I spoke to the service department they said that they need to order a new 12v battery and it would take over one month to get the part in. I'm currently in a rental that VW is paying for.

Splice the unstripped (black with white stripe) signal wire into a positive (+) 12 volt power wire from the vehicle. IMPORTANT: Jeep vehicles, the signal wire must connect to the battery and not the vehicle light. harness. Use the self-stripping connector provided. This wire provides power to the Wireless Controller.

VW is planning on allowing you to use the main battery for other things and probably be what you're looking for instead of having to go through the 12v. Yes as long as the ignition is on the 12v will remain topped up by the DC to DC converter. You can put a weight in the driver's seat and tap the power button to achieve this.

ixlr08. A quick search here would have told you that, yes, the ID.4 has a 12v battery. Nothing happens with the car if that battery is dead, it provides power to all the computers. Yes it is charged from the main (drive) battery when the car is switched on. Conflicting reports if the 12v battery gets charged while the main battery is charging.

When charging our solar power station I.e Bluetti or Ecoflow in our ID Buzz it charges at expected rate of approx 105w (8amps) for just a few minutes then the voltage on the Buzz drops to low side of 12v. I would expect to see high 13v or low 14v at a constant with "Optimised Battery Use" switched on. Why can't we have a Tesla style

3. The wheel lock adapter (star shaped nut) is with the tow adapter in the trunk. 4. The 12V outlet will not normally stay on if you leave the drivers seat (unless you put a weight on the seat). Instead, you should press the start/stop button on the right side of the steering column. This one baffled me for a while.

The entry-level ID.Buzz will include a smaller 62 kWh battery. However, VW has yet to set a price for the new model. Deliveries of the first ID.Buzz models will start in the next few months in the US.

1. Converts the 12V plug to 120V outlet. This can only provide maximum 120W or so. Enough to run a laptop, fan, LCD TV, cellphone charger. OR. 2. A full size inverter that has 1500W or more capacity (similar to the one above that Sun Wizard posted). This would directly clamp onto the 12V positive battery terminal under the hood and a ground
