Description
Part number 1H0907311H is a genuine <a href="/brand/volkswagen“>Volkswagen engine control unit for the Golf III and Vento petrol range, built between 1991 and 1997 — removed from a serviceable vehicle and tested before listing.
The module handles fuel injection mapping, ignition timing curves, idle control, and oxygen sensor correction for the Golf III and Vento petrol engines, working in tandem with the immobiliser transponder to authorise starting and maintain the correct closed-loop fuel strategy.
Common ECU failure symptoms on this generation include an engine that cranks but won’t fire, intermittent misfires at idle or under load, high fuel consumption, stalling in traffic, or a check engine light accompanied by fuel or ignition-related fault codes that persist through sensor replacement.
This is a used, tested OEM part matched to the original factory specification. Professional fitting is recommended and VAG-compatible diagnostic software may be required for adaptation.
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.
