How reliable is the Audi A2's electrical system?

I've heard mixed reviews about the Audi A2's electrical system reliability. Can someone provide more insight into this?

From my personal experience with owning an Audi A2 for 6 years, I have never encountered any electrical issues. With proper maintenance and care, the car's electrical system has been very reliable and trouble-free.

I've been working at an Audi dealership for the past 10 years and have seen quite a few Audi A2s with electrical problems. It mainly depends on the vehicle's maintenance history and the year it was manufactured. Some models have a higher chance of experiencing issues.

I've owned my Audi A2 for 4 years now and have had no major issues with the electrical system. However, I have noticed that the battery tends to drain faster during cold temperatures.
