Is a Relay Still Required to Install a P2 or P3 Brake Controller on a 2005 Porsche Cayenne
Updated 08/20/2014 | Published 08/19/2014
Question:
Another questions and answer, is all P3 controller are updated and no need a relay for VW or Porsche? How do I tell if the one I get is updated? Thanks.

All of the P2, # 90885 and P3, # 90195, brake controllers that we have now and the ones we will get in the future are all the newer versions so you wouldn't have to worry about that for your Porsche Cayenne. Some additional wiring will be required, see tech bulletin to the right.
On the off chance that you do get an erratic display the linked tech bulletin also covers that.
