ECU 98133028 NW – description

We offer a Denso MB275800-9791 ECU intended for the Opel Astra / Zafira with the 1.7 CDTI engine. The unit has been refreshed and the housing refurbished – the electronics have never been repaired. The Car Pass (PIN) code is reset (Virgin), so the ECU is waiting to be programmed in the car.

How to get ECU 98133028 NW running

The Car Pass (PIN) code is reset, so after fitting you program the ECU in the car with Tech-2 or OP-COM. You can also use cloning included in the price: send the EEPROM and FLASH files from your ECU or the whole ECU, and we read the data and return both units. For an extra charge we do EGR OFF, tuning and – on versions with a DPF – DPF OFF. The warranty is 6 months.

Numbers on the label

  • Opel / GM number: 98133028
  • Letter code: NW (98133028NW)
  • Denso number: MB275800-9791
  • ECU type: Denso 1.7 CDTI

Why 1.7 CDTI ECUs fail

The Denso module is mounted low, in the left front wheel arch next to the bumper, so it is exposed to rain, road spray and snow. A damaged ECU causes starting and injector control problems, uneven running and misfires. Run a diagnosis before you buy.

Matching by part number

  • Application: the Opel Astra / Zafira with the 1.7 CDTI engine.
  • Number to compare: 98133028 NW (98133028NW).
  • Model and year do not decide compatibility – the label does.
