REAL DIAGNOSTIC WORK. DONE RIGHT THE FIRST TIME.

Cintech Automotive Repair is an ASE-certified, family-owned auto repair shop serving St. Peters, St. Charles, and Cottleville since 1995. We work on all makes and models, foreign and domestic, from routine maintenance to the complex diagnostic problems other shops hand back to you unsolved.

We invest in equipment most independent shops don’t carry: PicoScope oscilloscope diagnostics, OE-level J2534 module programming, and OEM service data through Mitchell1 and Identifix. Our ASE-certified technicians use it on every job that calls for it, because a correct diagnosis is what makes a repair actually hold.

We’re not just a repair shop. We’re a shop that’s been part of this community since 1995, and we intend to be here for decades to come. Here’s how we got here, and why we still do it this way.

Cintech Automotive Repair is a family-owned shop that has been serving St. Charles, St. Peters, Cottleville, and the surrounding area since 1995. We built this business on one principle: fix it right the first time, or don't touch it.

That sounds simple. It isn't. Doing it right means investing in equipment most independent shops don't have: OE-level J2534 module programming, PicoScope oscilloscope diagnostics, and access to the same technical networks used by the best technicians in the world through our associations like our iATN membership, our affiliation with mitchel1 for the same OEM information the dealers use, or our Identifix database and contributions. It means our technicians actually diagnose your vehicle instead of guessing and replacing parts until something works.

We've seen what happens when cars get handed off to shops that aren't equipped for the job. Customers come to us after spending money elsewhere, frustrated and still broken down. We find what others missed. That's not a sales pitch. It's what our reputation in the community and our reviews reflect.

Maybe you don’t have the most complex check engine light or wiring nightmare that other shops won’t touch but; you do think you need brakes, or tires, or suspension work. The shop that provides the best diagnostic ability is the same shop who will do the absolute best work, with the correct parts for your needs. We stand behind every repair we do, and offer a hassle-free warranty process. If in the unfortunate scenario you have an issue out of town, we are proudly a 30 year member of the Napa Autocare Network which boasts a 2 year 24,000 mile nationwide warranty.

We're not the cheapest shop in St. Charles. We're the shop you come to when you're done wasting money on the wrong answer, or worse on parts that were never needed in the first place.

If you want it done right, we're ready.
