    Update on Lurching Issue

    I had the Turbo Cab in today to have the dealer look at it for using too much oil (1 qt every 300 miles). As luck would have it, an engineer from PCNA was there investigating a Turbo Cayenne that had been in three times for the lurching issue many of you have been describing.

    This particular car was a very early build (May '03) and apparently needed an updated tiptronic control unit to fix the problems. The PCNA engineer recommended it and said that would fix the problems. Interestingly enough, I also overheard him saying that he didn't want any of the data from the control unit dumped to the PST2. I'm not sure I understand why, one can only speculate unfortunately...maybe it's nothing.

    The PCNA engineer indicated that the problem was present on very early build Cayennes and should have been fixed by now. That being said, the dealership has taken in and fixed a number of Cayenne Turbos with similar problems from random build dates.

    I have yet to seriously encounter the lurching issue on my pepperturbo but I also haven't put more than 30 miles on the car since I got it The folks at the dealership seem to think that by applying a "kickdown update" as well as some sort of a "throttle" control unit update fixes the issue. Granted these weren't the most technical descriptions of how to fix the problem, but apparently they've fixed several.

    If there's anything I can do or anything you want me to ask, let me know.

    Re: Update on Lurching Issue

    Could you ask your dealer to provide more information like service bulletin number or any other technical info they got regarding the lurching, throttle, kickdown, etc. stuff? Thanks.

    Re: Update on Lurching Issue

    The techs are gone for the day, I'll ask em when I get back in town next week.
