This article provide by one of my blog reader,and i rewrite it to share How to solve Prosche Cayenne accelerate slowly.Hope you can find some useful info from it .Below show the experience of Tom.
I have a 2006 Porsche Cayenne Turbo S and noticed an odd issue just recently.
Upon heavy acceleration I’ve noticed a “staggering” or “shuddering” issue with the vehicle. There is no rough idle issues or idle problems when keeping RPM’s high (even in the 4k – 6k range), but only when I “get on it” and give the car some acceleration.
It doesn’t happen in any particular gear as well – only when accelerating hard. When the misfires start occurring, the entire car (including cabin) shakes rather violently.
I also have not experienced any transmission specific issues (i.e. high rpm’s and a mis-shift or extremely hard shifts).
When I brought Porsche Piwis 2 into the dealer today, I brought one of the tech’s out to take a ride with me. I went through and immediately was able to re-create the issue. The repair man connect Porsche Piwis Tester II and my car, at the end of the ride, my check engine light finally turned on…I was pretty happy about this because the dealer was telling me that it’s hard to get Porsche to provide warranty work if there is no check engine light (is everyone else’s experience the same with dealerships)?
The codes stated that there was a cylinder 6 misfire and the tiptronic transmission flag was also presented. The standard procedure from what they told me is to replace the ignition coils (and of course it’s on the tough side to replace – engine torque mount – you name it).

Diagnostics application is used for communication with control units. You can search for, identify, code and control program units, read out the event memory, execute complex processes, change drive links and execute routines.
Guided fault finding (GFF) generates a test plan for a fault code. This test plan shows the best sequence for carrying out tests. GFF compiles a list of recommended tests, documents and wiring diagrams
Actual values/input signals functions displays you the actual values and input signals of control units
Drive links/tests function displays the drive links of control units, allows you to change the parameters of these drive links and run test routines for individual control units
Maintenance/repairs function group – use this function to call up control unit-specific processes that cannot be implemented generically from the ODX data
Coding/programming function group – use this function to write coding values. Values can be coded automatically or set manually. This function group includes (Automatic coding, Manual coding, Customer-specific settings and Factory settings) coding modes
Logging – use this function to activate logging for diagnostics, guided fault finding (GFF) and measuring equipment applications. Temporary and permanent working log can be created
Filter – use this function to limit the view of the control units installed in the vehicle. In the diagnostic application you can create, edit, activate, deactivate or assign filters
Wiring diagrams application is the representation of physical connections and layouts of circuits
Measuring equipment interface is used for DC and AC voltage measurement, direct and alternating current measurement, diode testing, resistance measurement, continuity/open circuit testing, showing voltage, current and resistance over time (oscilloscope function)
