Some background - E70s and even the 3.0i were produced in two different configurations. One (early) uses a relay to turn the fuel pump on and lacks any kind of control mechanism other than on or off. The other configuration uses a control module, the EKPS or EKPM, to electronically vary the speed of the fuel pump. Turbo vehicles use the electronic module and some 3.0s do as well, I believe. If Legokcen has a relay, it doesn't use the electronic module.
