  1. Hello All, Please advise, I have an '04 Cayenne S for almost 1 year and I am using the IcarSoft i960 scanner. Recently had the suspension pump replaced at European Auto Wurks. I cannot communicate with the PSM ecu for starters. The above issue resets and fails on every drive. When I access DTC, KESSY, GATEWAY, and XFER CASE I get the code ( 1316 PSM CONTROL MODULE) in all of these windows. I verified good voltage on the fairly new battery. Replaced all 4 wheel speed sensors. There is no water ingress evidence beneath the floor boards. Verified brake fluid level. Cleaned both MAF Sensors. Verified no corrosion at ABS pump/ PSM module connector. Removed cover of the Xfer case motor and inspected brushes and look to have much life left. OBD II Faults cleared: P0021, P0501, P0507, P0306. Did not reoccur. Vehicle operates fairly normal while in failed mode. Thank you.
  2. Hello All, This car has 170K miles on it with the workshop code 1772. A friendly tech at the local european auto shop showed me on his Durametric when I first got the car 6 months ago, and said it was the pressure sensor. It only came on intermittently when very cold out, which is very often here in Colorado. Last week it failed hard and permanent. I would like to do some of my own troubleshooting. Can I buy a cheaper diagnostic tool or will I regret it. I see the Durametric harness with the CD to load the Durametric program on my laptop for $300. I see a iCarsoft POR-II for half the price. Will it do the trick? I see the pressure sensor is part of the manifold on the pump and no damaged wiring or plumbing so considering replacing that manifold assy. I see p/n 15-1524-0008, is this a good idea to purchase used? Would it matter if I bought the 15-1524-0008.2 from a 2010 vehicle? Also my owners manual only shows the left side fuse block and looks like they mislabeled the page for the right side when fuse 27 and 48 are for the leveling system, does anyone have solid prints for these? The MM I puchased on line does not address the fuse blocks. Thank you, Kent
