Why does my Porsche Cayenne Jerk when I change gears?
Sometimes, this can also show up as jerking when the PDK is going through 2nd to 3rd gear changes and accelerating between 30-50mph. The problem stems from the transfer case in the four-wheel drive system and is a regularly reported issue.
What happens if the transmission on a Porsche Cayenne fails?
Failure of the mechanism can lead to some wild gear shifts. Transmissions in the later cars are very complex and the technology involved is a closely guarded secret. Technicians at Porsche not trained to dissect the transmission and make repairs. Typically, they just replace the transmission.
Why does my car Jerk when I press the accelerator?
A car jerking may be a result of a very worn out acceleration cable. You will notice some signals for this symptom such as your car takes excessive time to respond when you press the accelerator and starts jerking. Another symptom is that if you take a look inside, the outer covering of the acceleration cable will be damaged.
What causes your gears to slip when accelerating?
They work with transmission fluid, so low fluid levels could cause damage here as well. Once the torque converter is damaged, your transmission will slip. A top-rated mobile mechanic will come to your home or office to verify the operation of your transmission, including slipping and any abnormal noises.

What causes the AOS to fail on a Porsche?
The AOS has caused numerous issues on Porsche engines. As the membrane in the AOS fails, oil is sucked into the air intake. Initially this can show up as a check engine light for fuel adaptations and the oil can be deposited on the o2 sensors causing emission faults.
What kind of problem does a Porsche 911 have?
Less common are leaks from the cam seals and scavenger oil pump seals. Valve cover leaks are obvious and fairly straightforward to fix on most models. The valve covers do not have a gasket – instead a liquid gasket sealer is used.

Why is my Porsche Cayenne making a clunking noise?
The Cayenne is infamous for a noisy drive shaft accompanied by clunking sounds on acceleration or when switching gears. This is usually caused by a failure in the driveshaft support bearing. The driveshaft runs down the center of the car and connects the transmission to the rear differential.
Where does the coolant leak on a Porsche Cayenne?
There are two likely spots for this to occur – the front of the engine or the rear of the engine close to the transmission joint. The leak at the front of the engine is most likely from the upper front coolant pipe, which slips out of its housing when the glue fails.
What causes a valve lift fault on a Porsche Cayenne?
A failing front O2 sensor will either not see or cannot react in time to the valve lift gas flow change. The slow response from the O2 sensor is not within the tolerance the engine management system requires and therefore a valve lift fault is set.

Why is my Porsche Cayenne leaking steam under the hood?
Once they degrade and a leak starts it quickly speeds to a point where large clouds of steam can be seen billowing from under the hood when the engine is running – steam powered Cayenne! There is an update kit available to permanently fix this problem and change the plastic pipes to metal ones.
