DIESEL DIAGNOSTICS MOBILE SERVICE runs on one rule. Tell the customer the truth, and only do the work that needs doing. That rule shows up in every estimate, every diagnostic, every repair we hand back.
Every technician is ASE certified. Every diagnostic is shown to you before we touch a wrench. Every repair leaves our shop with a 12-month warranty, written down, with your name on it.
Local car owners aged 25-65 looking for a trustworthy mechanic with honest pricing. If that sounds like you, we will take good care of your vehicle.
Four things we will not compromise on.
- i.
We diagnose before we quote.
No charge for a proper look. You see what we see, then you decide.
- ii.
We use OEM or premium parts.
Cheap parts cost more in the long run. You get parts that last.
- iii.
We back every repair.
Twelve-month, twelve-thousand-mile warranty on every job, in writing.
- iv.
We finish when we say we will.
Same-day service on most jobs. If it slips, you hear it from us first.
The work, not the marketing.
A look inside the shop. Real cars, real repairs, real customers.
