So you have two other options rather than remove the pump,
1. find someone with GlobalTis and SPS programme the pump with your cars VIN, this will overwrite the pump software and virginise the pump, you can then use your cars security code to program the pump to your car.
2. Use a diganostic tool called Carprog to read the security code from the pump on the car, then use Opcom to reset the pump using the code you get with Carprog, once thats done you can use the cars own security code to program the pump to your cars immo system.
Only other way is to remove the pump, if you do this i would strongly advise you to get the timing pin kit and lock the engine at the correct TDC position using the tools before removing the pump.
