Is you car's check engine light on?

The check engine light is a useful way of knowing that your car’s on board computer has detected something outside of your cars expected operating parameters.  The computer stores the diagnostics code which can be retrieved later and used by our highly trained technicians to quickly troubleshoot the underlying problem.

Customer Testimonials

“Doesn’t seem to matter what I bring in, Rex’s Diesel and Auto can tackle it.  I’ve brought in a Jaguar XJS, BMW Z3, GMC Acadia and more and over time and the results are the same: effective communication, reasonable prices, and excellent workmanship.”

   Derek Rowley

“Rex’s was amazing!  They saved me so much money!!!  I went to another shop for safety and emissions and came out with a huge list of issues wrong with my car that would have cost over $1600.  After a lot of pressure to get it fixed there, I decided instead to Rex’s a shot.  They were able to help me understand what was truly urgent and what wasn’t without any pressure.”
