Where can I buy comprehensive auto scanner good for BMW 530 and Volvo S 80 that can read car computer info not only engeen info?
You can buy a OBD2 compliant scanner online from a company
called Innova. These scanners are capable of reading all car codes
on every vehicle sold in the US after, I believe, 1998. The model
is Equus 3030. It worked fine on my Volvo S80. I was able to read
the problem codes and reset the check engine light.
