GM Diesel Enthusiast Must Have

The combination of this app and its concise diesel emission trouble shooting guide are invaluable! Using them, along with OBDlink MX+, I was able to resolve the “Exhaust Fluid Quailty Poor” issue that was on the verge of bricking my LWN diesel. Being able to conduct diagnostic tests to resolve diesel emission issues removes the haunting fear of diesel ownership. I give thanks to the developer for sharing his skill and automotive passion!

Duramax def test

Used it to run a service bay test to check what was going on with my sensors and def system. App is awsome and I don’t mind paying the $20 so the devs can keep this app updated. Awsome job on this. Will be testing more with this app in the future.

Does not support ‘old’ vehicles

I was excited to purchase this app and happily pay for quality. I was highly dissatisfied given the description in the App Store did not give caveat that there is not a very long list of supported GM vehicles. I had to find out after sending an email to the developer. Once I got that email I had to go to the Gretio support site and find a link of supported vehicles. This link should be front and center in the app description so an informed decision can be made before purchase.
