Check Engine Light & Diagnostics
That warning light finally explained — clearly and honestly.
When a dashboard light comes on, we run a full diagnostic to find the real cause instead of guessing or throwing parts at it. We pull the codes, test the systems, and then walk you through what we found before any work begins. You'll leave knowing exactly what's wrong and what it takes to fix it.
What's included
- Full computer diagnostic scan
- Clear explanation before any repair
- No guesswork or parts-swapping
- Upfront estimate

We fix it right
Quality parts, skilled techs, and a warranty that backs the work.
“I mostly own classic cars because vehicles nowadays are just computers on wheels, so it's hard to find mechanics who work on cars older than the 1990's. I sent my '64 GMC pickup to Dettmer to figure out what was wrong, and within 2 weeks it was fixed and running perfect. Since then I've sent all my classic cars to them with perfect results. It's hard to find a trustworthy shop you don't have to worry about — they take pride in the work they do.”
