Bridging the relay is just for diagnostic purpose, it won't fix anything, might be a wiring issue or bad contact in the plugs at the valve block cos DCV2, PCV and the transducer's values are not OK , troubleshooting is needed but you must understand diagrams and how the system works for that, there is a orange connector near the fusebox innthe engine bay, make sure it's well connected.... here are values from a working system
ACE INPUTS
1. DCVs (both) - .001A
2. Pressure control valve: 0 - .012A
3. Pressure sensor: varies between 16 and 19 but if it's out of that range the transducer is gone
4. Residual pressure: between 3 - 6 Bar but can be higher after the vehicle was driven or the ambient temp is low
5. System pressure: around 6 Bar fluctuating
6. Accelerometers: 0.01
for troubleshooting purpose: the resistance of both DCVs(top of the valve block, DCV1-toward front; DCV2-toward rear)= 2.7 Ohm, pressure control solenoid(on the left side of block) = 5.7 Ohm.
