Thanks everyone, very happy with this car. I just found out from a look through the previous service records that the previous owner installed an RSS crank pulley! And the car already has mesh on the front bumper to help keep crap out of the rads.
hi, what is this RSS crank pulley, what does it do? nice car, love those x 51's...
my car is also X51 and i have the connector disconnected as well, i hook it up once in a while and cycle the valves a few times to keep them loose, or whatever, i can imagine they might rust or just seize up from lack of movement at some point....i don't know what the purpose of them shutting down the open valves during acceleration is, but the explanation proffered makes sense, i was told that it has something to do with noise abatement here in deutschland, also could be...whatever it is, i like the sound of always open ... much mo betta... like i said, love those X51's
Agree the car looks wicked but minor changes make a huge difference, like LED lights
