Customer Testimonials

AG Diesel does a complete diagnosis of everything, it is amazing what can be found wrong that I did not even know about until I took a good look for myself! I appreciate the thorough evaluation of my 2002 Chev pickup, then the repairs are far superior to anywhere else I have taken it to. Thank you guys.


Great service from start to finish, Thank you


My experience at AG Diesel Repair was most excellent, the customer service was very awesome almost like your family and the employees were also very friendly, the shop is very clean and up to date. I will recommend you guys to everyone I know, my truck runs so awesome, you guys are the best.


Any one who is in need of diesel repair, I highly recommend this place. Shawn, the technician working with me, was very friendly and knowledgeable. Everything was done in a very professional manner. And most important of all, it was done with full disclosure, down to the most minute detail. Above all, a five star experience!


AG took care of my Volkswagen TDI when I needed a new timing belt. They kept me informed throughout the process and got me in and out very quickly. They also got me set up with a regular maintenance schedule so I don’t have to worry about what I need to be doing in the future. I definitely found my Diesel shop.


Excellent repair and very complete. Kept me informed and gave me written issues about the repairs.
