My understanding is that if you have Sport Chrono on a 991, then, it automatically comes with PADM. Please someone correct me if it's wrong.

I know this is true for the 991.2 (except for the T) - not sure about 991.1.

yes this is my understanding as well. Same in the 981 Cayman/boxster.

Has anyone with those knockoff PIWIS had a chance to look and see if the PADM mounts are a toggleable setting? It really feels like it would be.

It's not neccesarilly long lasting because the non electronic mounts fail too. The difference is the regular mounts are a reasonable price and easy to change making it an affordable repair.

The mounts are an option so it can be coded out. The option code is I140 I believe.

Hi,

My 991.1 has a PADM fault but the Durametric pro doesn’t access the PADM system. Can the failing mount be identified by unplugging the existing mount and plugging the replacement mount in prior to installing the mount? Thanks in advance.

Porsche parts warranty is 2 years, so if you had 4 go in 5 years out of warranty, you only had to pay for one, correct?

I had one go on year 2 of ownership, so 2016. No more problems with them since. You have to pay to play with Porsche and I believe in not bastardizing the car by going cheap, and that would definitely make me pass on buying a pre-owned car that had that kludge, as would 80% or more of any other Porsche buyer. If the car is too expensive to keep, consider going down-market rather than goofing up your 991.

Hey, Has anyone figured out how to code these things out it the PIWIS? Ive heard it can be done but I have not had anyone able to tell me where and it which control units it needs to be coded out of.

I have a PIWIS II and I have seen the options in the body control electronics section, I have not tried to code mine out.

In the instrument cluster module?

I have a 2015 Cayman with the sport chrono option and 16,000 miles on it, pretty much just a weekend car. I had the PADM warning come on, and my dealer has advised 1 of the dynamic engine mounts has gone bad, and replacement is required. Cost about 2500, all in. I typically drive in sport mode, not sport plus. My question is, since I have so few miles on the car, is this an unusual occurrence? Does this mean that the other mount is also likely to go soon, and require replacement as well?
Because I do not drive aggressively, but do use the sport option nearly 100% of the time, can that have contributed to the part's failure? Even with only 16,000 miles? Any advice, explanation? I am new to the forum, and this is my 1st post.

I have a 2015 Cayman with only 16,000 miles, and the sport chrono option. The PADM warning has come on, and after inspecting the car my dealer advises 1 of the dynamic mounts needs replacement. Repair cost about 2500, all in. I usually drive in sport mode, but not aggressively. My questions are, why has this part failed with such minimal mileage on the car? Can it have anything to do with using sport mode nearly 100% of the time I drive ? Should I expect that the other mount will fail soon and require replacement as well? This is my first post, and any advice/comments will be appreciated.

Below is a snippet from an article I wrote, pending publishing in the local PCA "rag".

Porsche Active Drivetrain Mounts (PADM): This feature’s unique function and utility are explained nicely below in a post from TOTAL 911 NEWS, a UK publication. They also provided the pic seen below. “Porsche included the PADM engine mounts as standard, for the 991.2 Carrera cars optioned with Sport Chrono. PADM was an option for the 991.1 Carrera and 991.1 Carrera S cars ordered with Sport Chrono.

“The (PADM) mounts are filled with magnetorheological fluid containing microscopic iron particles. Each mount contains two chambers, with a circular slot that allows the fluid to pass between the top and bottom chambers. At the centre is a doughnut-shaped electromagnet, which is used to control the fluid’s viscosity.” Further, “At low engine speeds, the fluid flows freely to provide a more comfortable driving experience. However, the voltage that reaches the electromagnetic is controlled by the ECU, with the map based predominantly on engine speed. As the engine rpm increases, so does the electromagnet’s voltage, creating a stronger magnetic field. This increases the chains of aligned iron particles, decreasing the fluid’s viscosity. Eventually, submitted to very aggressive driving will render the mount solid.”

TOTAL 911 NEWS also mention, with PADM engaged, driver will experience, “decreased ride quality, as it (PADM) increases stiffness at the rear end of the car, providing improved responsiveness when cornering. PADM is part of the optional Sport Chrono package, allowing the driver to activate the system with the Sport + position located on the rotary switch.” It cannot be denied that PADM is an advantage when engaging in aggressive driving, street or track."

Noting, if my PADM mount(s) were to fail, I'd probably just suck it up, and replace them.

thanks for explanation----I guess I will go ahead and just get it repaired, and hope the 2d one lasts much longer

Still leads me to my question early in in this thread.

Is there a firmer standard mount available as a replacement and what resister is needed to be plugged into the electrical plug to no trigger the error code.
