  1. My 08S with 108k gave me the sudden banging Wednesday during acceleration... thought I ran over something, til it happened again.... Searching the internet.... driveshaft support! Put it into Special Terrain Mode and crawled under to check, yep, shaft loose.... Normal driving and there is no sign of anything being wrong, drove 50 miles home on Fwy before starting repairs.... I'm starting to think my trips to Yosemite are cursed!!! Last year, 1st trip, a coil pack failed (second one) about a half hour out of Fresno on a Saturday morning..... found a replacement and was back on road later that afternoon... (after I got home, replaced remaining 6 coils). A couple month later, back to Yosemite.... leaving the park the first night, the melting snow and darkness hid a big pot-hole.... sudden blowout! (ultimately new control arms and 2 new tires).... The next day, cones in place.... 5 cars had blowouts while I was changing my tire that night! Planned a trip to Yosemite next week and Drive Shaft Support failure.... Fortunately I replaced the Thermostat, Water Pump and repaired the loose tubes in thermostat housing last month. Since I'm limited on time, I decided to go with the hose repair method. Can't really see any reason this won't last for a long time. This shows the rubber support failure: This is where I cut off the rubber support from bearing and housing, leaving the rubber that was attached to the bearing and housing. I had some 3/8" air hose that was just about the right size. I cut pieces 1" (25mm) long and tied together with SS Safety Wire. I think I actually used a total of 13. I tied them around the bearing first, then slipped the housing on at the top first, then used a screwdriver to compress each piece of hose at the bottom to fit into the housing. Once I got the housing in place, I used safety wire to hold the hoses into the housing. I figured the safety wire was a longer lasting product than cable ties. The fix works, no noise, no vibration on hard acceleration.....
  2. I just discovered that my failure in the thermostat might not be the thermostat but the wiper seal that's inside the thermostat housing. Information on some of the other forums got me to looking inside the thermostat housing and after a trip to the dealer looking at a new housing there is in fact a seal or wiper pressed into the thermostat housing that seals against the sleeve on the thermostat. The lip of the seal is totally gone on my housing and if I put in a new thermostat I would come up with the same problem again. Now it's time to find a replacement seal I'm going to try and find a PTFE wiper seal Sent from my SM-G920V using Tapatalk
  3. Next step is to replace the O-rings on the coolant pipe in the rear of the Thermostat housing
  4. Finished installing pipes in thermostat housing.... One pipe installed and epoxy spread on inside of housing for second pipe... I used the radiator hoses to hold the pipes in the proper position while the epoxy cures. Spread epoxy on pipe before installation... Both pipes installed I'm quite happy with the results..... and saved $300++ Glen
  5. Yesterday I got the pipes & housing cleaned and ready to install pipes....
  6. Guess I'm going to epoxy the pipes back in, both were loose..... Glen Sent from my SM-G920V using Tapatalk
  7. Great help! Thanks! Got into my '08S and found the pipe loose on the thermostat housing.... guess I'll try cleaning and using epoxy to reinstall.... the epoxy I use for golf clubs seems to work fairly well.... Sent from my SM-G920V using Tapatalk
  8. Problem fixed!!! YEA!... Turned out to be the pressure sending unit... Once I reinstalled the working Durametric, I did a road test while monitoring Oil Temp, Oil Pressure and Oil Pressure sender voltages. All was normal until the oil temp rose above 80C then things started to happen. Very erratic pressures and voltages, and when RPM was near 1000, all pressure sending stopped at something around .360V and something under 600mbar..... thus the deduction of sending unit failure. Ordered the sending unit from the local Dealer (got a good price!!! :-) ) and about 3-hours of work I replaced it (not the easiest thing to get to).....however, no more errors!!!
  9. The problem is the new software version for the Cayenne has basically been bricked for diagnostic... there are no actual values output from the SDI4 V8 engine module... This should be simple OBDII data readout...
  10. Okay, found a copy of the Durametric software, and it works and reports actual values. The oil pressure is approximately 2300mbar at idle, 640RPM (oil temp 70C) and 4200mbar to 4400mbar at 2500RPM Oil pressure reading is a bit eratic as well as voltage for oil pressure. Again, the problem doesnt arise for a while... I'll have to take it on a test drive again with the monitor attached and watch/record the errors when they happen. From the surface, seems like the sending unit!
  11. Yea! I found a download on one of my other computers of .... It works!
  12. The Actual values for the engine are not responding, RPM, Fuel trim, Oil pressure, etc. I have the car parked because I cannot diagnose the Oil Pressure Monitoring fault... Because Porsche periodically changes the game by switching DME suppliers and the like, Durametric is always playing catch up. And when Porsche does make an unannounced change, shops or end users are the ones that discover it and report it to the Durametric crew. That said, a couple of months is not at all unusual time frame for them to find a work around to address it, and often it can take a lot longer. I have always found the Durametric crew to be upfront when some problem pops up, so I wouldn't be quick to label their frankness as poor customer service. You may not like what they have to say, but they don't sugar coat things, or over promise and under deliver. At the end of the day, unless you have the bucks to jump for a PIWIS lease, they are still the best alternative................ Yea, but it's been a couple years since they said they would fix the transposition of the error codes... still not done on the Cayenne! The frustration has been being told it would be soon, fixing the current problem and having ther car parked waiting....
  13. Having issues with my Cayenne and went to use my Durametric software and there are no real time actual values available... Talked with Durametric nearly a month ago, they were aware there is a problem...sent data logs to them to help. Sent a followup e-mail to check progress... no answer. Called today and was told they don't know when it will be fixed. I asked if there was an older version to run that did work... No! we cant offer anything to help... no idea when it will be resolved... Absoutly the worst customer service attitude I have experienced... I have the Durametric version ... does anyone have a copy of the earlier software that worked?
  14. Thanks Dan, I'll consider them. After 19K on my Michlein Latitudes, still another year if tread left (they were in the car when I bought it used) they have performed very well and going to the new LRR Michlein (265/50/19 N0) has some interest.
