Hello to all,

Thank you for taking the time to read this.
As the title suggests I have an error since I bought the car. The guy I bought it for said that this error appeared when he made a facelift for the car (maybe he had a crash and decided it was a good moment to make a facelift).

The error's are:
1. When i start the car I get a battery low warning (i have charged the main battery and the old one, also i have disconnected the auxiliar battery and still the error wont go away as some suggested)
2. Radar Sensor blocked and Forward Alert Radar Blocked show every 5 - 10 minutes with the most annoying light that constantly flash every 1-2 seconds (seen in picture attached with a red circle)

I also made some pictures with some errors when I went to a diagnostician and some pictures with the car.

Please advice what should I do in order to get rid of the sensor error.
Also if you have any advice with the other errors I am all ears.
PS I have resolved the DPF error.

Thank you in advance for the help
