W177 A class not starting! Circuit 15!

Hello,
This is my first post 😊

I have a Mercedes A class W177 A180 1.5 Diesel
I bought it damaged however no airbags were deployed apart from active bonnet actuators. Now the car does not want to start and I don't think it's getting the full ignition.

It's currently stating Circuit 15 has short circuit to positiveCircuit 15R has short circuit to negative
also it is not detecting the driver's door however all electronics are completely working fine on the driver door.

Could you please guide me through to where is this circuit 15 and how could I check/rectify this issue of anyone has encountered this before.
I have also attached some pictures of the codes I'm getting.

Many thanks

Since your car is a W177, it's likely still in warranty. I would suggest contacting your local MB dealer and see what advise they have. The diesel model that you have is not sold in North America.
