Needed to check ABS fault in 1997 VW. Worked exactly as described. Found faulty RF wheel speed sensor and ordered new one from AutohausAZ. Well worth the investment.

I have a 2001 VW Cabrio that used to be my mother’s. The Check Engine light used to cause her concern. She’d get it checked and they’d tell her, “Don’t worry about it.” I’ve had the car for a year and the Check Engine light has come on a couple of times for me. In contrast, the Check Engine light has NEVER come on on my ’98 4Runner that we purchased new.
Rather than run to Auto Zone or Pep Boys every time the light comes on, I purchased this hand-held.
I found it rather easy to use and best of all, I can check it myself, log the results and reset the light. Well worth the cost; I’d recommend.

Took my 1998 VW beetle to the garage, they charged me to read the code then another 0 to do some repair work. Two weeks later the engine light came back on. This little reader and an internet search showed that the code is intermittent on these cars. Clearing it got it through the CA smog check and it hasn’t come back on since.
Also, the CA smog check caused the ABS light to come on (front wheels rolling, back wheels not) and the reader was able to identify that and clear the code for me turning the light off (and that one hasn’t come back either).
Simple to use, works well.
