Buzz 12v Strikes
I'm just adding a data point for future owners.
We (US) have had our 1st Ed RWD Buzz for 363 days and we woke up the other morning to the car only being charged up to ~64% and the 12v low. Got it towed to the dealership.
Thankfully, you all are VERY informative so I used prior posts and comments to figure out what was potentially the issue. The dealership attempted to say the issue was our home charger; however, I corrected them and told them to investigate the 12v and computer module.
They called and identified the computer module and rear heating element being faulty. Thank you all for your crowd sourced knowledge.
There's only one computer module in Canada and the heating element is being requested from Germany. We will manage.
Good luck to you all! We still adore our Buzz and still are excited to give tours.
