power steering is heavy at low speed

[Henry_texas]

My 2013 Cayenne get a heavy power steering at low speed. It looks like there is no power steering assistant under 5mph.

 

I stopped by the dealer twice. Told me that there is no problem. 

 

I did research on this forum and found that " servotronic control relay has been known to fail causing heavy steering. " . Dealer told me that my can doesn't has servotronic control relay at all.

 

any idea?

 

Thanks

What model do you have? You should be able to determine if your car has Servotronic by doing a VIN# search one any of many available websites that offer it. It might be bundled in a "package" depending on your model though.

 

One chap on another forum took his Servotronic fuse out of his 958 claiming it greatly improved steering feel at speed. He did note that the car became much heavier to steer at low speeds though.  If you have Servotronic - first thing I'd look at is the fuse. Second thing is hook it up to a good Porsche code reader and see what faults are hidden away..

Relay or the wiring is loose that connects into the rack. This can also be caused by a weak battery.
