IMMOBILISER BYPASS  see notes below * :
After three years of R&D in house, we have made a solution to free run these engine ECU version which uses the 1708201726 5WK48697 Siemens Immobiliser box after an unrepairable start error situation. The car will start with any key, there are no signs visible displaying in the cluster or by diagnosis. All your remote keys will continue in a normal manner. This service is made uniquely for the original vehicle ECU, all coding and VIN remain original. The immobiliser box remains in the car with all connectors attached. Subject to workload three days may be required to carry out this immobiliser bypass process. This is our own solution we do not subcontract.

We can clone your original into a compatible replacement making it plug and play.

This service will unlock all aspects of a used ECU, With the correct equipment and knowledge, you will be able to update the VIN, personalize & activate in the same way you would with a new part.

If you have a no communication issue we can do a static bench test and investigate a possible repair or replacement option.

We require your engine ECU, immobiliser box and key with your contact details.
* Note: These ECU's have a folded seam it will be visible after our work that it has been taken apart!

Please Note *
Immobiliser bypass for these engine control units are based on software versions and not all are covered at this time.
Send us an image of your diagnostic report showing ECU identification so we can confirm our bypass service will meet your requirement.

    After three years of unreliable engine starts and two new immobiliser boxes later, this car has been running faultlessly for the last 12 months on the ECU Decode Bypass.
