This module suits an Opel owner with the 1.8 16V Z18XE engine who needs to replace a first-generation Siemens engine ECU. We supply the original, later GM version: its housing design was changed and it does not carry the faults of the earlier model. The memory has been wiped to Virgin state.
The list is not exhaustive and the numbers have the final say. Check GM 55351702 and Siemens 5WK9 1720 on your own ECU label – a different ending means a different module. If your car is not listed, email a photo of the label to sale@ecusale.com and we will confirm the match.

Instead of adaptation, you can have us transfer the data from your old ECU – cloning is included in the price.
Can I start the engine without the PIN code?Adaptation needs your car’s Car Pass code. If you do not have it, cloning the data from your old ECU, which we do at no extra cost, may be the solution. |
How is the new housing different?It has a different shape and ribbing, but it uses the same 3 mounting points, so fitting it needs no changes to the car. |
Do you ship exactly this number?Yes. You receive an ECU numbered GM 55351702 and Siemens 5WK9 1720, as shown in the photos. |
Other numbers for this engine are listed in the Opel Engine Control Units category.
