hi all first id like to say that i love this forum.. and ive been on it for a while.. just never got up to the task to register lol.. anyhoo

i hope u guys can shead some light into my problem cuz its really annoying

i got a Cayenne turbo 2008 (Facelift) and i seem to have a problem.. now the thing is ive gone up against a Jeep cherokee SRT8 and ML 63 and a G55.. and i seem to put them way behind me from standstill

now the problem is its been around 1 month and i noticed my car isnt wat it used to be when i accelerate full throttle before my boost gauge used to stick on 0.8 bar all the time except during gear changes.. however now i noticed that my boost gage keeps fluctuating from o.4 to 0.6 sometimes 0.7.. never to 0.8bar like it used to..

i took it to the service center here and they dignosed it.. nothing came up

i was wondering if anyone here faced the same problem or if someone can give me tips as to wat i can do

3 days ago i went up against an srt8 although i was slightly ahead of it it was definatly catching up to me.. its kind of annoying lol

anyhow thanx in advance ^_^

peace !!

 

Sounds like a boost leak or diverter valve issues. I have a B5 S4 and whenever the boost is inconsistent those are the usual culprits.

Porsche should be able to do a pressure test to see if that is the problem.

 

Wow i did not know it was faster then those trucks... that is bad ***
