  1. Lol, and to think I was expecting a picture of a BMW. Still in the family!
  2. I’d suggest ohming out the wires as wiring issues can be tricky to find otherwise.
  3. Thanks! I ordered the Mann filters thinking they were the same/similar to OEM, but they may differ. I may try an OEM set next. Unfortunately discarded the old filters. Anyone have observations of this type of noise?
  4. Wow, okay. I would really expect it to be bled by now. Is the car taking a long time to heat up? If you drain all coolant try making sure the right amount came out.
  5. How much have you driven it? I recently did similar work and observed that I needed to turn left/right pretty aggressively to help bleed the system and get all the air bubbles out. Sounds like it either needs to be bled or the shop made a mistake.
  6. You should be able to see something by inspecting around the front of the engine area. See anything?
  7. Hi all, I did a large amount of work to my 08 Cayenne Turbo and am now hearing diverter valve/pressure relief sound if suddenly letting off the gas, especially at lower speeds. It reminds me of what I have heard on other cars, but I’ve never had it on this car. It’s not a “honk” per se; it’s what I consider normal DV sounds. What I replaced; - Coolant pipe, thermostat, water pump, acc belt - Air filters (Mann) - Spark plugs I inspected the DV lines and did not see any issues, but maybe the hard line got damaged? I realize I did a lot of work on it and may have caused this problem. Or I might have fixed something as I replaced some aging vac lines that came apart during disassembly. I was also going to check the airboxes as maybe one/both is not closed correctly. I am hoping this is normal or related to the non-OEM air filters. Please let me know your thoughts!
  8. Following up - going to 10W40 slowed/stopped the leak, at least for now.
  9. It may be inevitable, just hoping to reduce the leak a bit. Slightly thicker oil is something I will try. Anyone had success tightening the bolts? Or anyone had success doing this repair without a lift?
  10. Closing the loop on this one - it was indeed the pump. I purchased a used unit ($115 versus $725), installed it, and have been trouble-free since. The replacement pump is fairly loud, but this may be typical from what I have read.
  11. It appears my oil guide housing is leaking (2008 Cayenne TT). From reading others' experiences, it is a painful repair. It appears to leak more when the car has been sitting; if driven daily, the leak appears minimal. Are there any strategies that have worked besides dropping the subframe and resealing it? There were comments of poor bolt choice for 08 and possibly other years - might bolt tightening or replacement help? I may try a different oil weight; currently using Mobil OW-40. Any advice would be greatly appreciated! Pretty frustrated with this one.
  12. Removing the 5A fuse made no difference, nor did removing the Servotronic relay. It seems plausible that the relay or transducer on the rack has failed, but the pump whine is significant. At a dead stop, I only really get steering assist if I rev the engine; it appears the pump is the issue. Unless it is known that pump failures are incredibly rare, and Servotronic problems can cause pump whine, I am leaning towards replacing the pump. Thoughts?
  13. I checked the 5A fuse - it was OK. I flushed the steering fluid with a liter of Pentosin 202; it was coming out pretty clean at the end. Unfortunately, the issue persists. Oddly, I have noticed that I seem to have more steering assist at initial startup, before closing the driver's door. The iCarsoft scanner did not show anything although I will try again. It might not be able to access the steering module, or the steering codes may be under a different controller. Is it known that the Durametric can see the steering controller and identify codes? I might try removing the relay next to see if that makes a difference, although it sounds like the steering goes heavy when they fail. Or maybe I can pull the fuse. Other suggestions?
