Question What OBD2 scanner gets everything?

I've got what I thought was a pretty solid OBD2 scanner but when I brought my 1998 318ti in to a small BMW only shop they were able to pull way more codes, like 9 vs my 2. The format of them was different too, here's what they gave me:

Codes found for check engine light:
DME codes:
108 supply voltage, continuous
148 interface immobilizer
80 secondary air system
27 idle load fuel trim, limit reached
97 tank leak detect, minor leak
32 idle speed control valve mechanics

Antilock brakes (abs/ASC/DSC):
102 throttle actuator mechanical defective
99. Throttle valve potentiometer
103 brake light switch circuits
My scanner gives me codes I'm a bit more familiar with,
type codes.
  • Do I need a scanner that is "smarter" or one that is "dumber"?
  • Like if I get a OBD2 <-> USB cable would I be able to use a simple serial program to get a dump of all of these?

Best way to go is a copy of the dealer software INPA. I have it running on an old Panasonic toughbook and it gives everything. Also useful for newer cars.

I forgot to mention the cables and interference are via eBay. Or get a genuine one from the dealer.
