Description
Part number 036906032M is a genuine <a href="/brand/seat“>Seat Leon engine control module for the 1.4 petrol hatchback, removed from a running vehicle and verified through bench testing before despatch.
This ECU controls sequential fuel injection, ignition timing and advance, idle speed stabilisation, and closed-loop lambda management on the Leon 1.4 petrol engine, communicating with the vehicle’s immobiliser and instrument cluster to confirm a secure start and maintain the correct fuelling strategy under all load conditions.
Typical failure symptoms on the Leon 1.4 petrol ECU include a cranking no-start with no sensor faults found, rough idle that worsens after warm-up, lean or rich fault codes that return immediately after clearing, hesitation under light acceleration, or a hard-start condition that only affects the vehicle when fully warmed through.
Supplied as a used, tested OEM part matched to the original factory specification. Professional fitting is recommended and VCDS or a compatible VAG diagnostic tool will be required for immobiliser 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.
