1 pointForgot to make final update. The car is up and running well. To summarize, had to replace multiple parts: broken plastic pipes that the splintered serpentine belt broke (3 of them by radiator) Repair coolant leak at back of engine (where the coolant vent Y line connects to the rubber hose) Replace power steering pulley (cracked when I installed replacement belt, you guessed it, ruined the belt too) Belt tensioner Belt tentioner pulley Replace serpentine belt itself, twice (first replacement split once power steering pulley broke Replaced valve cover seals Replaced cracked coolant splitter pipe (going into front of engine) Replace oil cooler pipe (since it came with part #6 already) Repaired a cracked wiring harness for injector #2 (was damaged during the job - brittle and one wire frayed, shorting the wire to other side of injector harness - bad thing - battery short) Most of it was very easy, just time consuming to get to, as cayenne turbo is famous for stuffing all sorts of ungodly wires all in a tiny space. Hardest part was waiting for the parts to arrive, after issues diagnosed. After I repaired everything, car would not start. Thought it was battery, but turned out to be injector wire shorting. Once I rewrapped harness, issue went away and all great. Battery was also leaking slightly so I had it replaced with new one under warranty. DONE. Now, have few small sensor things to replace and it will be better than new.
1 pointThe install is great news GSpence2, i’m sorry to hear about your O2 issues. Hopefully you’ll get them resolved soon. I did the intercooler upgrade at the same time as a tune so I couldn’t tell who the real boost hero there is. I'm guessing both because the car pegs the boost at .8 at WOT every time now which would be the tune but it holds it well thanks to those big intercoolers. Good luck and please keep us posted. Joel
1 pointThanks, I will have a go during lock-down, gives me something to do!

1 pointA couple of days ago my head unit started cycling off and on every minute or so. I found some posts that these things are notorious for failing so I started looking for a place that would repair it. Luckily I found the Becker office in Saddle Brook NJ, called them, and they emailed me instructions how to fix it. Apparently my XM SAT provider caused the problem. It required a reboot as per below: WARNING It was brought to our attention, that the PCM 3.0 and 3.1 units have been rebooting continuously on a number of Porsche vehicles at the moment. It seems that a signal was sent by SiriusXM which has caused this issue. SiriusXM and Porsche are investigating currently and are working on a fix. VERY Important: Please DO NOT replace any parts or hardware on a vehicle, due to this issue. In order to rectify this issue, you will perform a “PCM handover” (also known as a PCM Hard Reset). Instructions are listed below; Press and hold the PCM>>Info button for approximately 10 seconds until the PCM reboots. Immediately select the following from the PCM; CAR>>OPTION>>Set PCM System>>Reset PCM>>Vehicle Handover>>Yes>>Yes These instructions can also be found in the respective Owner’s Manuals for affected vehicles. Hopefully this may prevent Dealership / workshop visits. If your vehicle is already at the workshop, recommend that the technician update it to the latest available software level. **PLEASE NOTE: Performing a PCM Hard Reset will also erase all of the radio presets and Bluetooth connections and these will have to be reentered by you after the reset.** In order to rectify this issue, you will perform a “PCM handover” (also known as a PCM Hard Reset).
