Scanner question

[Pdwight]

Probably like Dracula Movies....been done to death...but

I have a Durametric for my Boxster , but I also have a code reader from Harbor freight that seems to be almost worthless (Thanks mom for the Christmas present). Does anyone have a CRP123 or Launch X431 and how well so they work ??

I was trying to read codes with my Harbor Freight for my good friend on her BMW128I and nothing showed up......nothing...saif couldn't communicate with vehicle , I tried every way and nothing...so any idea if I decide to acquire a new general purpose scanner in the future...and I am talking under or around $200 bucks...bot 5 grand.

Thanks in advance

Dwight
