Any idea what would cause two servo valve motors to fail?

Oh my days....... I sure hope they remembered what went where, when they put it back together again!

Pardon my language, I realize this is a family forum but this is becoming an FING NIGHTMARE.

I haven’t had my car since 10/20.

I have had it with all of this.


I almost bought a new Taycan instead of enduring all of this, and now I wish I had.
I'm truly sorry for you having to endure this sh*t show.

The only consolation (?) I can offer is that you Taycan owners aren't alone.

Our Genesis EV has also had some recall issues, and it's also hit or miss with them whether they really seem to know how to address each. During the last recall repair appointment, for a loose piece of windshield trim, they cracked the windshield. Replacement required an additional 4 days, but in the end it was done correctly. Our loaner was a refrigerator white base Hyundai Elantra. Driving THAT for 5 days will really make you appreciate driving a nicer car!

Hope it's all resolved (correctly) soon!

Not a long terms solution (just remembered you asked for pic of this high tech solution once before, so here you go):

Also would not work in actually freezing temperatures (no way to defrost a frozen windshield from the outside, also the fog inside would likely freeze on a frozen windshield).

PS> Service let me know the car is ready (and heating), picking it up later today! :party:

That is the same question I've been wondering about. Talking to service, they've seen many failed heaters, but never seen this yet, so my car is a pioneer. There is nothing whatsoever that I customized with, or adjacent to the HVAC system, so the only thing I can think of is either weak parts batch, production process deviation (new trainee installing things at the factory?), or some unique way I happen to use the car (wouldn't be the first time, have been told my different people I tend to use things differently than majority of users). The bypass valve I believe is part of the "heat pump" mechanism, which is optional in some countries, maybe not tested as well because not present in all vehicles?

Servos fail because they wear out.

I’m also in pinball and have had to replace servos that died.

Ha! Are you using the night vision display in case your windscreen fogged up?

I always have it up on the IC. It is useful at night when blinded by oncoming cars, also useful when I see something in the shadows and I want to confirm is it just a shadow or something live/hot. I still scan it during day driving, it became part of my instrument cluster eye scan.

My car is not even 3 years old, under 20K miles. Servos wearing out that quick seems like really poor reliability design and/or quality assurance. The effort required to change those servo motors must make it quite expensive for Porsche warranty too, unless of course this ends up being charged to the supplier of the servos, so Porsche doesn't mind?

Well the servos I had experience with were “Hobby King” servos to make spotlights pan around the pinball playfield. I found a more robust replacement from a hobby shop for RC cars.

One would hope the servos Porsche users are much higher quality with much longer duty cycles. That doesn’t change the fact that replacing them is a nightmare though, if they should fail.

That gutted dash photo is sobering.

I had two servos shot on my Turbo S, my car was 2 years old and had 12000km on it.
It's a defective batch, no two ways about it. Meanwhile my Audi S8 is 13 years old and every little part of the climate control is operating perfectly.

Of course the problem is with the supplier. I think the supplier was Pierburg?

But but but.... we count on you to help us feel fortunate for our relatively trouble-free Taycans :)
