Hello everyone I am new to the site and have a problem that I hope you can help with.. I own a 05 cayenne tt. It is heavily modified which includes techart wheels and body kit, flashed ecu, full exhaust from the manifolds back, 8 piston brembos with 15in two piece rotors, 4 piston in back, techart lowering mod. larger intercoolers with dv's installed on top of the motor close to the intake. A couple of months back I had an alternator go bad and porsche replaced. I dont drive the truck everyday but last week I got a PSM failure on the dash. Called Porsche and they said to bring it in Monday. Well I decided to poke around and see if iI could see anything under the hood that was obvious. As I was looking around the dv's and the intake I noticed that the boost hose had completely come off where it connects to the intercooler on the driver side. Who knows how long this has been like this, probably they never attached it correctly when they did the alternator replace. I re-attached the hose, but in doing so noticed a good amount of oil that had made its way up inside the boost hose only on the side that was dis-connected. The other side was was completly dry. Is this normal?? Anyway cleaned all the oil out from inside the hose with sensor cleaner and also cleaned the intake sensor and the housing before putting it all together. Reset the computer, started it up and all is now fine.. My question to you is do you think any damage was done from the air entering the engine directly through this hose that fell off and was not filtered at all?? Thanks in advance, Bryan

 

How long was it like that? Unless you are in a very dusty environment I would think that a couple of hundred miles or less of unfiltered air would not be too big a deal. I have had the same thing happen on my 1.8T Audi motor... although with that one once the hose pops off the motor dies. Kind of keeps it from damaging itself with no filter. I am surprised the Cayenne would even run with an entire bank of unmetered air flowing into it.
