BMW E46 M3 & E39 M5 EWS Removal

The EWS control unit is a major part of the BMW security system ensuring the engine will not start unless the correct ‘chipped’ key is used.

This EWS system can also be troublesome as these vehicles start to age often resulting in costly repairs.

If you plan on removing your EWS control unit for tracking their vehicle or prepping the engine for an engine conversion into something else then EWS removal ensures a smooth transition. This can also be useful when installing second hand DME control units.

After this firmware modification, you can physically remove the EWS control unit from the vehicle, rewire the starter exciter and start the car. This service totally removes the factory immobiliser function.

The cost of this EWS removal service is £150.00 inc VAT.
