In Austin, shops are busiest on Monday mornings and before holiday weekends, so a mid-week appointment gets a car seen faster. Labor rates across Texas vary by neighborhood and by shop type, from small independents to dealership service bays, and mobile mechanics now cover many routine jobs in the driveway. Before authorizing a repair, ask for the estimate in writing, whether the shop warranties parts and labor (12 months / 12,000 miles is common, some offer more), and whether it can provide a loaner or a shuttle. Check the listing for hours, the makes the shop works on and its Google rating, then call ahead, since walk-in capacity is limited at smaller shops.

Hours are published for 5 days a week. On most of those days it is open 8 am–5:30 pm. Note that it does not open on Saturday, Sunday. Hours in the United States do change around federal holidays and long weekends, so a quick call before a special trip is sensible. You can reach Modern Diesel at (512) 717-2777; calling is usually the quickest way to ask about availability, prices or directions. More information is available on its website, moderndieseltx.com.

Customers rate it 4.5 out of 5 on Google across 161 reviews, placing it among the better-regarded diesel engine repair in Austin.

Austin is in Texas, in the South, where summers are hot and humid, winters are short, and severe storms in spring are a fact of life; businesses run air conditioning most of the year and many open early to beat the heat. US addresses list the street number and name, then the city, state abbreviation and ZIP code, and Austin follows the same pattern; a suite or apartment number such as Ste 200 refers to a unit inside the building. The map link on this page shows the exact spot.

Another week has passed and I still have not received any call or update regarding my car or its whereabouts. There has been no response to my messages or phone calls. The shop is not communicating with me at all. This situation is completely unacceptable. My car was moved without any consent from me, and I never signed or authorized anything for that to happen. Until today, I still do not know exactly where my vehicle is. This is highly unethical and extremely unprofessional.

My experience with this shop has been extremely frustrating and disappointing. The first time I brought my car in (2025), it was returned to me with the same check engine light still on and the air conditioning not working—even though it was functioning properly when I first dropped it off. I later noticed another customer review describing the exact same issue. Since I barely used the car afterward, I brought it back in January 2026 under their warranty, showing that the vehicle had been driven less than 50 miles since the original repair. They told me to bring it back, which unfortunately turned out to be a big mistake. Communication has been consistently poor. Thomas and the front desk staff provide vague answers and never give clear timelines. It took them about three weeks just to provide the first diagnosis in February, along with an estimate of $3,500. Then in March, they suddenly “found” additional issues—many of which are the same problems other customers have mentioned in their reviews here. I regret not reading those beforehand. By April 22, they finally returned my car after nearly three months in the shop. The final bill was close to $5,500 for all the supposed issu
