Description
Postal EWS (immobiliser) delete service for BMW E39 525i (M54B25) MS43. This service is carried out on your ECU, which you must send to us.
This product is for the EWS (immobiliser) to be removed from your engine’s ECU.
Unfortunately the EWS / immobiliser system can often fail, you may be looking to fit a second hand ECU which is not coded to your car or you may have done an engine swap and need the EWS removing to allow your new ECU to run. In some instances you may need to cut and join 2 wires but we can show you how to do this.
You will need to send your ECU to us to have the EWS removed.
In most instances we also offer Plug and Play ECUs with no need to send your ECU to us.
If you are looking for a bit more we can also offer tuning your ECU with the EWS removed or even a Plug and Play Remapped ECU.
