Description
Part number 1H0907311 is a genuine <a href="/brand/volkswagen“>Volkswagen engine control unit from the Golf III and Vento era, covering petrol engine variants produced between 1991 and 1997 — removed from a serviceable vehicle and individually tested.
This ECU manages ignition timing, fuel injection, idle stabilisation, and lambda sensor feedback on the Golf III and Vento petrol engines, maintaining the correct air-fuel mixture and spark timing across the full engine operating range.
A failing ECU on this platform can cause rough idling, poor throttle response, high fuel consumption, intermittent misfires, failure to start, or a permanently illuminated engine warning light that cannot be resolved by replacing sensors or ignition components.
This is a used, tested OEM part matching the original specification. Professional installation is recommended and coding or adaptation with VAG-compatible diagnostics may be required to complete the fitment.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
