2001 Volvo S40
I am trying to get my car past Emissions, but it failed due to a "failure to communicate" issue. I have been advised to have my on board diagnostics tested.
1. Is there any way that I can figure out what's wrong without having to go to a dealership?
2. If I do have to go to a dealership, how much (approximately) would this cost, and what exactly happens?
have the same problem?
