Car making a strange noise?
Start with the right test.
Describe what the vehicle is doing in plain words. OYENA gives you the exact physical check to run before you buy parts, swap sensors, or lose unpaid diagnostic hours in the bay.
Built for the technician holding the wrench
You are the real asset. When you diagnose vehicle faults faster, your shop makes more money and your reputation grows.
1. Works With 0 Codes
Strange shudders and rattles rarely trigger a check engine light. OYENA structures diagnostic paths from acoustic and physical symptoms alone.
2. Zero False Specs
Generic chatbots invent false torque specs that crack aluminum heads. OYENA is strictly grounded in verified factory service bulletins and OEM manual specs.
3. Test Before Buying
Never tell a customer "let me buy this part and see if it works." Show them verified factory evidence, test the component, and fix it right the first time.
4. Fast in the Bay
Runs cleanly on any Android phone, tablet, or workshop PC, even with intermittent cellular data in Nigerian and international repair bays.
