Get a faulty OVP or pull it out of there. This will definitly disengage abs BUT also the ECU. Emission control is all mechanical. It's drivable..before pulling the ovp, take your car for a run and warm it up. In warm condition "limp home" mode will be quite near emission control. Especially on w201 newer than 87.
BUT this is probably not recommendable
You'll have to get someone to confirm this...On the models with two fuses; is one use for abs an the other ECU?!
