Porsche Repair Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Being a newer model the info is somewhat limited here.The radar sensor for the ACC usually is active at all times.The radar detector usually uses a different signal separate from the ACC radar sensor signal so the radar detector shouldn't interfere with the ACC.The only way to be sure is to have it installed or mounted temporarily to the vehicle (the RD) and then operate the vehicle and see if it acts up or interferes with each other.If found to both operate properly you should be o.k.I have seen several RD in models with the sonar sensor with no issues before but this may not be the case with all of them.
Unfortunately I don't have the exact info if this will interfere for sure here or not.I don't know if anyone will have this info with the 2015 or 2016 yet.One thing the dealer can and should do is contact their tech support to see if they have had any experience with this model with interference yet.Their tech support may know of any testing that was done for this issue here to see if there will be any problems.This is probably the best way to find out for sure without ordering and finding out later on.
