2005 Cayenne S Hesitation upon acceleration.....

[skala57]

Hello Everyone Again!

I'm a little upset. My cayenne has 44k on the clock, and I'm getting a little sick and tired of this 2 to 3 second delay before take off. Anytime I make a turn and press the gas to go, there is this delayed reacation that I get before moving forward. It sometimes does it even when I'm just going straight. I've read online that there are some people that have fixed this issue with a software update to the DME? Is this true? I've even reset adaptations on the tranny. This seems to work for a few days then it goes right back to the delay again. Does anybody know what I can do to fix this issue? I've done some upgrades to the car, but this is even going on before when it was bone stock...

Upgrades....

Fabspeed cat deletes

Fabspeed maxflo exhaust system

Agency cold air intake

With these upgrades, I feel a big difference in initial thottle response, but the cayenne feels like someone has tide a chain to the rear bumper and will not let me accelerate with ease, like I'm pulling a boat or something. Anyone have any light they can shed on this topic? Thanks in advance....

how long have you had it ?

I've had the car for 6 months now. The delay has been there from day one. It's nothing that I can't live with, but I'd like to get rid of it if possible. I've done coolant pipe upgrade, starter, spark plugs as preventative maintenance.

Mudman, if you can shed some light on this, that would be awesome...thanks

Is there anyone out there that knows something about this issue? Just as a recap.... its a lag in acceleration... The engine and tranny work perfect. Everything has been maintained including all the above also water pump plus the thermostate... So as you can see, the cayenne is perfect except for this darn lag in acceleration... Thanks

The symptom you describe would most likely be described by Porsche as either non existent or a feature, either way thank your lucky stars you tranny is not an 04 because after mine was changed to an 05 it was much better but not fixed

The are a few factors causing this, the e-gas adaptation which maps your driving habits, the transmission mapping which is bizarre at times

I also have a very personal opinion that the S does not have the power to use the mapping provided in the transmission

You adapt to it or you bail, there are part time fixes but nothing permanent sorry

Funny thing is, we sure the same opinion. I was thinking the same thing a few weeks ago. Anyways, thanks mudman for the input.
