Watch out when buying a reader...there are lots of folks out there that have the wrong idea on the ODB or other digital diagnostic equipment. They are only as good as your information source and quality levels allow.
1. $150.00 is not going to get you one of any real quality.
2. Most of the 'generic' readers do not have the software module required to read the Volvo's system. You end up having to buy that as a separate item.
3. If you don't have the corresponding cross reference to identify the codes, you will get a nice list of numbers and no way of understanding what they mean.
