    Check Engine

    Warning light, power loss or uneven engine operation.

    Typical symptoms

    Warning light, power loss or uneven engine operation.

    • The Check Engine light stays on or flashes
    • The car loses power, jerks, or the engine idles unevenly
    • Fuel consumption increases, smoke appears, or you smell fuel
    • The fault returns shortly after clearing it

    What we check

    Computer diagnostics, error analysis and repair plan.

    • Read errors with diagnostic tools
    • Check symptoms and live engine parameters
    • Verify likely causes before replacing parts
    • Agree repair estimate before work

    Possible causes

    • Lambda sensor, MAF sensor, spark plugs, or ignition coils
    • Fuel system or intake system issues
    • Emissions system faults, DPF, EGR, or catalytic converter
    • Wiring, loose connectors, or faulty sensors

    When to contact the workshop

    • If the warning light is flashing
    • If the car loses power or enters limp mode
    • If the engine runs unevenly or makes unusual sounds
    • Before a longer trip if the warning light is already on

    What you can check before the visit

    • Whether the fuel cap is tightened properly
    • When spark plugs, filters, and oil were last replaced
    • Whether the issue appeared after refuelling, rain, or engine washing
    • When the warning appears: cold engine, acceleration, city driving, or highway

    Common questions

    Can I drive with a Check Engine light?

    Sometimes the car still drives normally, but if the light flashes, power drops, or the engine runs unevenly, book diagnostics quickly.

    Is clearing the error enough?

    Not always. Clearing a fault without finding the cause usually hides the problem only for a short time.
