Hello, just curious if anyone else is having similar issues? So far the dealer has tested the vacume system for leaks and it passed. Also fixed the speed sensor depth by adding a spacer (porsche recemended fix for hesitation) the heaitation is very evedant and always there unless driving fast then it just disapears.

what kind of gasoline that you use?

Looks very similar to when I had my throttle valve go bad. Does it have trouble holding a speed with cruise control on?

At my dealer they showed me with the bumper and intake channelling off, you could see the valve shake. At high throttle settings, the valve is basically parallel to the airflow, so if it's shaking it doesn't really affect the airflow much.

+1, sounds like there's water in fuel.

Hello and thanks for the feedback. I use premium fuel. I have fueled many times since this issue. Always high octane.

Ill definitely ask them to look into that. I havent tried cruze control however under a mild constant throttle there is a bit of a surge that is constant, car speeds up for split second then bogs down slightly then power back in then out. Very noticable at low speeds.

Even the best and reliable gas stations get water in the gas once in a while. If all fails, flush the gas tank and get new fuel. If it was the fuel, use your cc receipt as purchase proof and send the gas station the invoice if it's not covered by Porsche. I went down this path before, it was a BMW. Replaced fuel pump, fuel injectors, fuel filter, and checked vacuums. It turns out to be water in fuel. I only gas premium.

It actually seems to be a defective throttle body. If under warranty, have the dealer check it out.

Miles pls?

Interesting, that's never happened to me before. I'll keep that in mind if all else fails! Not sure how easy it is to drain that tank

I will ask them about it. It has been in twice but seems like they did not do a full analysis of the situation. it's going back in on the 21st. I can keep you guys updated on the outcome. The car is still under warranty.

I posted a video above that shows the KM's on the car in miles id say ~20k.

Exactly how mine was. Since I have PDK, I also had very abrupt shifts too since he computer couldn't get the RPM just right when it dropped the clutch. But yeah in a gear it would bog/surge/bog forever. Eventually when it gets bad enough you get a red engine fault "reduced power ok to drive on" or something message on the MFD, and some other faults. When you get that you get like zero power, and have to turn off/back on to get the power back. I had to pull over and restart like 6 times to get to the dealership.

Thank you so much for this feed back, It's great to learn from other peoples experience and really helpful. I will mention this to the tech and ask him to have a closer look. Sounds like it could be a common issue..

This may be a Capt Obvious moment but try premium fuel from DIFFERENT stations, fuel manufacturers in your market.

+1 this may be a fuel issue, and +1 on checking-out the TB. Easy enough to get to the TB.
