So with some help from ECS Tuning I found out fuse 22 on passenger side fuse box keeps blowing. It doesn't blow until you turn on the seat warmer. Also it doesn't matter which one you turn on - you can turn on the driver first or passenger first and it will blow. Where can I look now? Do they have a relay that controls both seats? If so where? I know on the previous years its under the dash but when I looked on the relay box underdash mines empty vs the previous years in that particular spot there was a relay.

Today my Porsche Cayenne turbo 2008 as same your car. check engine light On, and fault code is P1248 (Basic boost pressure adaption)- I understood that the value of boost pressure will adjust Turbo charge through DFI module. But I don't know how to re-adaption by my PIWIS. Can some one help me to fix it? Thanks in advance

were you ever able to fix this? if so how?

hey man let me know where at.. im not far from duluth.. pm the info.. maybe i can look this weekend for you

hrmm what about this knob underneath the drivers dash?

no coding needed.

So my guess is the previous owner installed an aux/USB setup.  Many of these systems means removing the changer from the fiber optic network and replacing it with this.

 

See if you put it on CD changer, if that little box activates and or does something.

when i do put it on cd changer the box works with rca cables however i cant close the glove box.. i have not been able to get the aux cable to work though

Did you have to purge any air as well?

no i did not.

dealer recommends it every 48k or 6 years. It has a filter built inside the reservoir and supposedly the PDCC system is very sensitive to any dirt in the system.. $50 a sense of security is good for me.

Based on this it looks like you can do it under the hood..

Briefly, the PDCC reservoir has a built-in filter, the Powersteering reservoir not. This should be the reason.

Are you sure about that? From what I see the part numbers are the same for both the PDCC and Steering reservoir.

I believe Porsche recommends to change the PDCC reservoir every 48k miles or 6 years. Does anyone know if you need to do the same for the power steering reservoir? If not I wonder what is the difference between having to do the PDCC reservoir changed vs the power steering?

no codes or anything and runs fine.. just paranoid.. but its almost like a small knocking sound or valve clatter.

Hey guys i just got delivery of my new to me 08 CTT.. i am going thru the service records and about 12k miles ago when the previous owner took it in for service they replaced it with a Bosch plug part number 999-170-130-90.

From what I read this plug is for the non turbo models.. Did they install the wrong plugs or should it still work fine on the Turbo model? If it is wrong does this harm the motor in any way?

Looks pretty highly optioned as well. Congrats. The only thing in my hunt that is keeping me away from the 2004-2008's is the PCM change in 2009. Love the interior color on that tho.

 Thanks it was actually highly optioned when I looked up the build sheet.

For those that did I have a question for you. What did you use to remove all the old rubber on the bearing of driveshaft.. I saw a video of a guy using cutting wheels and sanding it down with that.. I dont think I want to go that route..

The one that is pictured above is part # 955-355-579-51 for the piece that included the check valve. from the pump to the "Y" split and to the engine and firewall" I paid $133.34 probably cheaper online tho, if u dont mind waiting.

thanks!! just what i needed.

04 TT, same fault, "brake booster warning".Same problem as TopGun2000. the hose/plastic pipe is cracked at the connection (bottom end). Most likely due to heat exposure. Wrapped electrical tape (for now), i guess 3/4" heatshrink will also do.P/N is 7L5-611-931 G. Cleared code, seems ok.it is under pass side engine cover (remove blue washer lid, remove torx screw at lid, loosen rubber gasket around, remove that "+" screw lock thingy, remove plastic cover, and it's right under the plastic cover.)15 minute job total.Thank you Renntech, thank you Durametric!

I found the problem: a cracked vacuum line (on the top of the hose at the "931" mark)!!! :cheers:DSC_0012.JPGObviously there was another old leak which was fixed by the previous owner in a JB Weld way. :jump:DSC_0010.JPG :renntech:

Thank you very much!!! i have the same issue and it was this hose. I will order a new one.. thx everyone who contributed!

Also it should be normal at cold start for car to idle high at 1krpm then dropped down correct after about 30-40 seconds?

I noticed when I get on it sometimes it surges like not enough fuel. I know it's not coilpack or plugs cause I just changed them. I also notice when I come to a complete stop the RPM drops like the car is going to die. Someone told me possible fuel pump as well. So today I started the car and pulled the 13 fuse and car idle just fine. Then I inserted 13 fuse in and pulled the 14 fuse and the car wanted to die and struggled to stay on after a few seconds. What does this tell me?
