A check-engine light is a symptom, not a diagnosis. We find the actual fault before we quote the fix - so you never pay to replace parts that weren't the problem.
Parts-swapping is the most expensive way to fix a car. A code tells us which system complained - not which part failed. We test the circuit, the sensor and the mechanical side before anything gets ordered, and we show you what we found in plain language.
You approve the repair with a written estimate in hand. If it's not worth fixing, we'll say that too.
A flat diagnostic fee, quoted up front - and if you have us do the repair, we put that fee toward the job.
Reading a code takes seconds; knowing what it means takes testing. We'll always tell you the code, but a real diagnosis is what saves you money.
The fault is still stored. If it set once it will usually set again, and it's cheaper to catch early.
