I am in Australia, and just had the brake hose replaced. They did a full flush and also had a software update. "WPK0 - Re-programming PSM Controller: Optimized Software update for Porsche stability Management control Unit. This Update optimizes the brake pedal feel on recuperative and hydraulic braking"

Feels like a new car now, the braking is so much better.
Mine was done yesterday and I experience the same. So much better.

Dealer told me they did a flush and that they technically could not do without a flush. However I did not ask if it was only the front or both.

My car will be in for 30.000km service in 4 weeks so I will see if they do the flush again (it’s covered by 3y service contract). If they don’t do it I’m wondering how I can proof that it was done in case of warranty issues or when selling the car.

Received recall letter. Phoned to book my car in, no hoses available, don't know when they'll have any, will call me when they do. Pressing things a little more, do you think it will be 30, 60, 90 or 120 days or sometime next year? At this stage cannot provide an estimate.

done yesterday. They did flush the circuit but I can't say that it feels different.

What I noticed :
- they have a new retrofit Weissach package for free. They don't mount back all the parts so car is lighter... I have to check if the back seats are still there.

- pressure was +0.3 bar on both front tyres. When asked why, I was told we always follow what's written on the door. Yes, but that's the recommended pressure for 20", car is now on 21" ....

Since they have not charged you for it, it cannot be the Weissach package - that has to be, like, 10% of the car’s value or something. Oh, wait, it’s a Taycan.. yeah, you’re probably right.

Sorry to hear of that experience, but good on you for checking on their work.

Just posting my experience. Maybe it helps someone, maybe it doesn't.

Got the ARB0 recall letter early August. At the time the Dealership didn't have the parts in stock.

At 29000km car popped a warning that I should replace the cabin filter. I ignored it since I was due for 30k km service soon anyway.

Booked my 30k km service for September 13th. Was told the ARB0 recall couldn't be performed at the same time due to lack of parts. After reading @Maelstrom's undercarriage thread, I panicked and rescheduled the service to September 20th. The reschedule didn't go smooth. Went to the dealership last Friday to drop off the car. Waited 25 min for the garage Assistant to even acknowledge me until I exploded (the 25 min wait + the screwed up reschedule took their toll)

Suddently the ARB0 recall was available to me and two other software updates. Did the service + ARB0 plus whatever the other two updates were.

Ended paying €298 (including 23% VAT) total for the service of which €119 were for the cabin filter.

The brake feel changed substantially. I never complained about how it felt previously but it definitely felt like a race car breaking. Car would definitely "dive" as soon you'd apply any brake pressure. Now it's very very progressive and linear. No more "diving" feeling.

Only thing that hasn't cleared from my app yet is the stupid warning ⚠ about the recall. No idea when it will dissappear

On September 5th I was driving my 2021 Taycan 4S on my way to the Gym at 4:15 am, at that time there hardly any traffic. As am merging on the 101 southbound at the nearest on ramp everything seemed ok, as am driving along at 60-65 mph, I came to a downhill and the car was gaining speed, I stepped on the brake pedal to slow it down and to my surprise the brake pedal went all the way down to the floor! I had no brakes and gaining speed, my first thought was if the brakes had failed I would either crash the car against the freeway sidewalks or try to find a place where I can crash without hurting other drivers, fortunately I kept on pressing the brake pedal and it built up some pressure to slow it down but not to stop it, I kept my cool, but I was shaking knowing that I had no brakes! after a few miles the car was slowing down and was able To get off the freeway and pulled into my gym’s parking lot that luckily has an uphill and it helped to slow it down to a complete stop. At this point there was no warnings or error on the dashboard until it came to a complete stop, the message read “PSM failure” and to visit the workshop, nothing about the brake failure that had just happened! And it was after 2 hours, the failure occurred at 4:15 am and that did not show up until 6:12 am. I went into my gym to calm myself down after this horrible experience and after an hour or so I went back to my car and that is when I saw the warning, after a while I called Porsche road assistance and left the car where it was because Porsche road assistance couldn’t send a tow truck quickly, I revived a call from the tow truck company at 9:00 am and met them at the location, I explained to the driver what had happened and as he drove the car out of the parking spot brake fluid started to spray,out of the driver side font caliper, and there was a poodle of brake fluid under the car. The car was taken to Westlake Porsche and was told later that the recalled brake lines had a total failure, they apologized profusely about what just happened to me and promised that it issue would be taken care of, the following day I had a trip planned and left the car at the dealership for further review. On my return, September 19th I placed a call to Porsche customer service and filed a complaint and was assigned a case number, they requested picture or any media I had for further review, on that first call the first thing out of the representative was , do you want us to buy the car back? Then proceeded to take the info from me, two day later I received a call from a lady based at the Atlanta office and was rather condescending, she asked me again about the incident and I expressed my concern and disappointment about this awful experience and how come Porsche hadn’t advised the 30,000+ Taycan owners that have been waiting for the parts to be available to stop driving the cars until parts were available and the potential of total failure ? No response to that, I express how dangerous it was to be in the position I was put in by the negligence of Porsche and why it would take to send out another letter warning them on the danger this faulty brake lines could potentially be, is Porsche waiting for someone to get hurt
? Or worse, died in an accident due to total failure of these faulty brake lines. At that point I was told by Melissa S. That my case would be reviewed within 3-5 business days and see what options they would have for me. Today Oct. 2nd I received a call from Melissa S. From Porsche corporate to tell me that they would not buy the car back and that the issue with the brake lines had been resolved, no apologies, no alternatives, nothing! I am extremely disappointed about how Porsche has handled this incident from the very beginning, by not having the recalled parts available for several months, by not warning us the 30,000+ Taycan owners that these faulty brake lines could potentially fail anytime without warning, the fact that I’d been calling my dealer to get updates on these parts and been told that they weren’t available yet but as soon as my car had them failed the parts appeared a couple of days later. I’ve been a loyal customer for 23+ years and spent millions on these vehicles to the tune of over 100+ Porsche purchases over the years, this clearly has showed me how much or how little a loyal customer like myself means to Porsche, I am attaching the pics I took of the warning messages I received, 2 hours later and the second one 5 hours later , after all the brake fluid had been dumped on the freeway and ground

Wow. I'm so sorry to read this. I'd expected the car to still break using regen and only the last 15km/h being affected by brake line failure. Back when I got the recall notice, my SA was of the opinion it wasn't that critical because of how Taycans break but in hindsight, all previous recalls I received, had signed-proof of delivery letters but never ever got the warning triangle in the Porsche app like with the ARB0 recall.

Consider yourself lucky surviving and not totalling the car.

I hope that by now the ARB0 was performed on your car?

The triangle eventually disappeared after a few days (about 500 km driving it). All good now.

Not good.

The parts suddenly appearing will simply have been your car being bumped up the queue due to an actual failure.

But how they're dealing with this on such a critical part leaves much to be desired. I suspect they didn't fancy tens of thousands of cars being parked on their lot waiting. No excuse though. An engineering led company (cough) should never have let this see the light of day for such an "obvious" thing as pipe length!

BTW, I believe someone on here mentioned that if you push the parking brake button quickly a few times it activates an emergency brake. It's meant to be pretty violent, but for future ref...(must use the electric motor fully).

I think you only need to press it once (in case of sudden illness like a stroke) and it will do the emergency braking (which you pointed out very well... will be violent).

Taycan Emergency Braking
PRESS AND HOLD P button

Understood, but when your brakes go out what goes on in your mind isn’t exactly reach out for the owner’s manual, there is a very real sense of urgency, panic your survival instinct kicks in, in my case I was absolutely concerned about other drivers on the road that I could potentially hurt: how about a parent taking his/her kids to school ? This is by far one of the most stressful and scariest experiences I’ve ever had. Totally preventable had Porsche advised us 30,000+ owners not to drive our vehicles until parts were available.

We need to be aware of Press and HOLD P before we need it.
Bad thing is that using emergency braking means only one hand on steering wheel.

Understood, but when your brakes go out what goes on in your mind isn’t exactly reach out for the owner’s manual.
Firstly, I'm puzzled that the dual hydraulics didn't provide brake action with the single hose blowout in the front. Clive reported this also. There is no way to test it, of course. I understand you will get significant extra pedal travel, but the unaffected hydraulic circuit will engage the brakes on two of the wheels if you push hard enough. I understand you are not supposed to pump the brakes. This will tend to empty the primary reservoir and you will lose all brakes. Just push hard nearly all the way to the floor.

Second, in cases where there is a rare full failure of the hydraulics, many modern cars have switched to having the electric emergency brake where you press and hold the P button. As I recommended previously under Clive's similar incident in Britain, have all drivers go to a parking lot and try it once or twice to get brain trained. That P button brings the car to a rapid, but smooth stop via a completely separate system at the rear wheels. It works great!
