It does sound like your battery could be the issue. A weak battery can cause low voltage readings and poor starting, especially in cold weather. I suggest you start by checking the battery. You can do this by using a multimeter to measure the voltage. A fully charged battery should read around 12.6 volts when the car is off. If it's lower, you might need a new battery. Please let us know how it goes and if you have any further questions.

This error code suggests a communication issue between the DME-DDE (Digital Motor Electronics - Digital Diesel Electronics) and the IHKA (Integrated Automatic Heating/Air Conditioning System). This could be due to a weak battery, as previously suspected, or a problem with the wiring or connectors. I recommend you first address the potential battery issue. If replacing the battery doesn't resolve the problem, you may need to have the wiring and connectors checked by a professional mechanic. Please keep us updated on your progress.
