Description
Part number 028906021DK is a genuine used, tested Engine ECU Control Module for the Seat Ibiza II, specifically the 6K1 body code variant fitted with the 1.9 TDI diesel engine. The Ibiza II 6K1 was a compact and practical hatchback produced in the 1990s, and its 1.9 TDI engine was known for strong fuel economy and reliable low-end torque from the Bosch injection system.
This ECU manages the 1.9 TDI indirect or direct injection system, controlling fuel injection quantity, injection timing advance, turbocharger boost pressure via the wastegate or VGT actuator, and glow plug pre-heat duration. It calculates fuelling corrections from the coolant temperature sensor, needle lift sensor, and mass airflow reading to optimise combustion across all operating conditions.
Drivers of the Ibiza II 6K1 1.9 TDI with a failing ECU may experience pronounced power loss at highway speeds, repeated entry into protective limp mode, excessive smoke from the exhaust at light throttle, difficult cold starting in winter, or fault codes for injection timing and quantity plausibility that return after clearing. The turbo may also appear to underperform due to incorrect boost targeting.
This unit was recovered from a written-off Ibiza II 6K1 and tested against the 028906021DK OEM specification before despatch. Given the age of the platform, installation by a technician familiar with classic SEAT and VAG diesel systems is recommended. Coding requirements are minimal for this era, but immobiliser matching may be necessary. Returns are accepted within 14 days.
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.
