Hi everyone, just joined after buying my first (2003 955) Cayenne Turbo yesterday.
Sadly, my first post is in the form of a desperate plea for some knowledge
I went to collect my Cayenne in response to an ad from over 300 miles away, apart from being in need of a new battery, the car seems in great shape with plenty of bills and full service history to show it has been looked after in it's 140,000 miles of use. I bought it and took to a local place to replace the battery and set off home.....
Everything was going great until around half way back when during an overtake on the highway (I floored it), there was a complete loss of power. I managed to limp to a safe place and took a look. It will start and tick over perfectly, but when trying to rev nothing happens except some backfiring. It is possible to drive very slowly by just touching the throttle, but any further pressing causes spluttering, jumping and dying.
My initial thought is that I have popped off or split an intercooler hose. I can't see any problem in the visible areas (near the intake plenum), and can't hear any unusual sucking or blowing noises when I try to rev it but had no tools with me to strip things down further to investigate.
I'm returning tomorrow (Sunday) to where I left it (2+ hours away) with tools, but I guess what I'm asking for is a little insight to whether you guys think I' m guessing the problem right (or any other alternatives?) and whether there are any common weak areas on the boost hose/intercooler side of things to check first?
I did have a little bluetooth OBD device with Torque with me, but no errors are shown as stored (in this limited way!) and no warning lights appeared on the dash. I will have an iCarsoft with me tomorrow to check further.
Would a catastrophic boost leak like a popped hose cause the symptoms described and also not throw up an error or engine warning light?
Any thoughts would be hugely appreciated!
