Frequently asked questions
The check engine light came on in my car in Hyderabad — how urgent is it?
It depends on the light behavior: If the check engine light is SOLID, it's a non-urgent fault but should be checked within a week. If it's FLASHING, stop driving immediately — a flashing check engine light indicates an active misfire that can destroy the catalytic converter within minutes. Metre Per Second performs OBD scans for ₹500 — we read all fault codes and explain each one clearly before any repairs.
How much does it cost to fix a check engine light in Hyderabad?
The OBD scan to identify the fault costs ₹500 at Metre Per Second. The repair cost depends on what the fault code reveals: loose fuel cap (₹500 cap replacement), O2 sensor (₹3,000–₹9,000), EGR valve (₹2,500–₹8,000), MAF sensor (₹2,000–₹8,000), catalytic converter (₹8,000–₹30,000).
