Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I drive my C4 all year round up here in the great white north and have a set of Blizzak LM 25s (bought used). Most of the winter driving has been in wet or dry road conditions, with limited snow. However, yesterday we got 4" of the nice light fluffy stuff and I decided drive the car to see how it really handled in the snow. Here are my observations PSM "On" made the car hard to drive as it was intrusive. With it off, I found the car predictable and far easier to control, especially when going sideways ABS seems very sensitive. It would pulsate even without an impeding lock up. Turn in is was slow and the car really wanted to go wide, especially when PSM was "On" Overall, the car did not feel as surefooted as it did last year Does this mirror others' experiences in deeper snow or is my suspicion that the tires have come to the end of their useful life (despite having decent tread left) perhaps valid?

POST 2Original post

I turn PSM off when the roads are snow covered. It makes the car easier and more fun to drive. I have Blizzak's as well, and the same experience with ABS.

POST 3Original post

PSM can be a PITA because it can slow your momentum in deeper snow instead of just letting the tail wag out a little. I often turn mine off while reminding myself that it's not that big a deal because PSM is never completely off and that it will re-activate itself if the sensors detect that I'm slipping and I tap the brakes.

POST 4Original post

Driving aids are a Nightmare for snow switch em off.

POST 5Original post

I think it depends on how and where you are driving. Generally, I find the PSM to be too intrusive. The PSM system in our Cayenne is far less intrusive - it will allow you to swing the rear end of the car out, and if you catch it on your own, it never makes a peep. If you let it go just a little too far, it will kick in and save you. The PSM system in the 911 "corrects" you almost immediately, which takes some of the fun out of it. If I'm just driving in town, I tend to turn it off. If there's any driving above 50 mph, then I keep it turned on.

It also makes the car slightly understeering. Without the PSM it's easy toturn the car with rear wheels too. +1 I also can say that 911 is very predictable and easy car to drive on snow and ice, looong slides are just fun... PS. Yokohama IceGrip iG30 studless.

POST 11Original post

I think PSM is for when people don't want to think driving or have trouble driving in adverse conditions. When starting my car in the morning hitting the PSM button to turn off the PSM is second nature. Here are some shots of my car having fun, in a photoshoot I did last year after a day of skiing.

POST 16Original post

psm beats pms any time. ahh moving forward . PSM should stay on ... Except for those that practice on slick surfaces in wide spaces, w system off , that they may learn to drive on there own utilizing the hand brake lift /release ...and throttle on off ...(induced over steer , trailing throttle over steer ) still practiced by Walter R. (Porsche pilot ) ongoing 48 years + / - . Some time all the technology at hand won't save you. That is the reason to test test test , before you need it the most.........MJ.

POST 17Original post

Question: Does the PSM have the ability to "learn" driving habits? For example, can it let a little more slide occur if that becomes more frequent. (I have been told this, but do not know if it is true) ~~~~~~ Experiment and practice with both settings, then you will know when to use ON or OFF! For me... Fun: PSM = OFF empty parking lots, around town, perhaps even a windy mountain road (little or no traffic) Speed: PSM = ON Fast as possible to ski areas. Higher speeds on freeways, road trips. Thoughts on using PSM = ON: From ice racing on Georgetown lake (PURE ICE), I have more fun slipping and sliding with PSM=OFF, but with PSM=ON, my times are much faster. Keep in mind, that my fastest times are when I only "lightly" engage the PSM, thus keeping the slip angle under control. On ICE, even one long drift and you lose a lot of time. Also, PSM has saved me on ICY bridges, and heavy traffic-accident conditions (lots of cars crashing, while I steered through...). BTW - Snow tires do not "store" very well. they tend to harden and lose their grip quickly - even if the tread looks good. During the second season, they just don't have that snow/ice stickyness they do when they are fresh. Then on the third season (if the tread makes it), they feel tired and slippery. Granted, they are still better than all-seasons, but fresh is best.

POST 18Original post

I think it depends on the conditions really. I bought Pirelli Wintersports...and in 3 inches of snow with temp no lower than -10...they are awesome and sooooo much fun with PSM off. Predictable and pretty precise. I can throw the car exactly where I want it. Lot's of fun. When in these conditions, I find PSM is not a nuisance at all. It lets me slide 1-2 feet before it kicks in. So for commuting to work. It's fine. Actually going out an playing, I turn PSM off. Unfortunately, I live in Fort Mac. The temp regularly falls below -20 all winter long. Last few days were -30 to -40. There isn't a lot of snow cause it get condensed down and packed so dense, it's like ice. In these conditions....the Pirelli's are complete and udder ****e. As soon as the temp fall below -20, it's like driving with 4 hockey pucks. Even on completely dry/clean streets or highway. At any speed, the whole car feels like it's floating a bit and the traction loss is subtle...but I can feel it. Luckily, PSM has kept the car straight many times. It is VERY annoying as it's constantly on sometimes, but it has kept my C4S on the street and away from the street parked cars/trucks. Next year, I think Michelin x-ice tires are in order. We get snow...but more packed snow/ice than inches of fresh powder, so I need better cold weather tires than snow grip tires. What were we talking about? oh yeah, PSM. I like it. I love having the option to turn it completely off, but really do appreciate it on my 996. I've driven other cars with their version of PSM and this one is the best implementation I've ever used. sean

This might be the issue... New ones next year I am thinking.
