Hi all,

I have a 2017 991.2 base mode (CPO only-month-old new to me 21,450 miles on it )
I have been struggling with an ABS / PSM fault/steering lock fault/parking brake fault
It has 2 times a month now.

Any suggestions or ideas are welcome.

Thanks

Isn't it under warranty? I'd take it to a dealer to get looked at.

they say it's common problem
I don't believe it twice in a month

it happens again today.......... not good

Mr. Big

It happened to me once after exiting a steep driveway at an angle (to avoid scraping the front lip) as described in the above tech bulletin. Does it happen to you when driving normally or after entering/exiting a driveway?

Interesting. I have a drive entry that I hit 3x week where one wheel is off the ground on my 2018 Carrera T. No fault codes (yet).

thanks for the reply every time faults quote need to go to Porsche dealer to reset. I think I got lemon car

Mr. Big

I don't understand what you're not getting here. You have a service bulletin describing exactly why it's happening to you, so wouldn't you think the problem isn't your car, but the driveway? I'm willing to bet if you get a new car the same thing will keep happening.

Thank you for the comment.
I agree that a consumer should not have the burden to have to go to the dealer every time this issue happens. My dealer is great but I don't want to see him once a week for this. Frustrating...

Mr. Big

I'm going to induce mine to throw the codes again to see if the POR II diagnostic/reset tool will erase the codes.

I know this is an old thread, but since I didn't see this information anywhere else, I wanted to follow-up to state that I was able to clear this fault in my 991.2 with a Foxwell NT710 OBD scanner tool. So that probably means other Porsche scanners such as the POR II can do it as well.

I seem to hit this fault about once every other year, so not nearly as often as some others report, but still enough to be super annoying when it happens. Previously I always had the dealer fix it, but this time I tried myself. Bought the Foxwell scanner for this purpose (though I'd been intending to get a good OBD tool for a while).
Clearing this fault took two passes, since a lot of the systems had "Check PSM fault" errors that I couldn't initially clear. But after clearing what I could including the underlying "Front right speed sensor, implausible measured values" fault, then turning the ignition off and back on and making a second pass through the faults, everything cleared up nicely.
It's possible I could have done it in one pass if I knew what I was doing. Next time I'll try...
