Was out for a ride in the curvy secondary Missouri back roads today & thought I noticed a throttle surge; I thought nothing of it until I noticed the Turbo S to be uncharacteristically sluggish out of the next hard curve. I was making 1 psi of boost & no matter how hard I tried to accelerate, 1 psi was it! No check engine lights, no messages in the info center either. Got home & parked in front of the garage to look up any info in the manual (I know - a waste of time). Went to start up to pull in the garage & the boost gauge shows 17 psi before I even cranked her over. Then the engine fired off only to immediately shut down again. Did this 3 or 4 times before I called 1800Porsche for a flatbed. Any ideas? Sure glad I made it home! First car I've ever owned that left me stranded!

 

Check one of the hoses that connects the intercooler to the the turbo. I had the exact same problem last weekend at Sebring. As it turns out the left hose came dislodged and I lost the clamp. Very easy fix if that is what it is. Look under the left and right rear and see if the hose has become lose or completely dislodged.

 

Thanks for the tip.

I got under & checked; all intake hoses on both sides are secure. I tried to start it again after it sat a couple hours & this time it continued to run. But I did get a solid lit check engine light now. I'm going to go ahead & let the flatbed haul it in as I am 45 miles away from the dealer & don't want any roadside issues.

Flatbed just picked it up. I'll see what the dealer in STL says on Monday.

 

Good luck, please post the outcome

 

Good luck and keep us posted.

 

Get the N17 looked at. I bet thats the problem

 

Y-pipe to tb boot?

 

Well, I got my Turbo S back today from the shop. Turns out that there was an issue with the turbo pressure sensor connector. The connector was "repaired" per the warranty operation.

I find it odd that such a fault would render the car to a state of complete failure like it did, but I suppose these days of electronics dictate such.

Has anyone had this issue before that I may have missed elsewhere in the forum?

 

i had the same issue with my car more than a year ago and till now we didn't find the leackege source , and it keep giving that there is a vacuum leak , and they didn't know what to do with it , because once i turn off the car and turn it on back every goes back perfectly
