Choosing the best OBD-II scanner for Porsche vehicles

In this article, we take a look and review some of the best OBD2 scanners for Porsche. With hundreds of OBD-II scanners on the market, it is overwhelming for many Porsche owners to figure out what is the best OBD2 scanner for Porsche.

While you can diagnose Porsche check engine light with a standard obd2 scanner, you can not diagnose airbag, transmission, and other systems without a scanner that can read Porsche specific fault codes.

Scanners we review here range from $140 up to $700 and can diagnose multiple Porsche systems including Engine, Anti-lock Brake System, transmission, airbag and more.

1. Autel MaxiDAS Professional Scanner

Who is this scanner for?

The Autel MaxiDAS is a professional level diagnostic scanner for Porsche and other makes. While it is the most expensive scanner on this list, it is also the cheapest scanner that you can get that will offer similar functionality to a dealer level scanner.
What do we like?

The Autel MaxiDAS can not only access all Porsche systems and modules, but it can also carry out sensor activations, programming and display live sensor data from all the modules.

Another advantage of the Autel MaxiDAS is that it covers almost all makes and makes and is not just for diagnostic Porsche vehicles.

What don’t we like?

This scanner is a bit expensive for Porsche owners who may only use it a couple of times.

If money is not a concern this is without a doubt the best Porsche scanner for the money.
