3 Weeks in New Taycan and rattling noises

[PlugmeIn]

I have had my car for 3 weeks, it is a blast to drive and hear are my concerns so far.

1. when I hit bumps there is a popping noise coming from back of interior of my car. It alternates between the back right and left corners and sometimes from the passenger side. I plan to take it in but wanted to drive a little to have a list of items.

2. Regen braking- I thought this was a feature you should leave on to help with brake wear and also driving, however I select it and it does not stay on and then get notice on the dash that regen will not work now. not sure what condition I am creating but maybe need to read more about it. The fact you have to select it each time you get in the car makes no sense.

Lastly I wanted to again thank everyone on this forum, I have read for 6 months about everyone’s thoughts and input while waiting for my car , not sure I could have gotten thru waiting and not cancelling, I am much more knowledgeable than my dealer. I did hear from others I have a good service department and hope this turns out to be true. I have a standard Taycan, Gentian Blue and I put a Xpel PPF film on front and ceramic coating on car.

1. Check the flexible tabs (for attaching straps) in the boot (under the top edge). There are two - left and righ hand side.

2. Recuperation - off by default. Manually enable with button on steering wheel - press = always on, press and hold = auto, Sport and Sport Plus drive mode on by default, Range Drive mode always off, Individual Drive mode you decide.

Switchable by design and possibly by policy.

Brake recuperation is much better and more effective for recuperation than overrun recuperation (via the button or Drive Mode).

Regen braking can't be turned off. The button on the steering wheel is for lift-off-pedal recuperation.

The rattles and squeaks are solvable with a mere 50+ pieces of foam all over the place. I was down to one rattle that I just could not locate. Fortuitously, my windshield was broken and had to be replaced. Happy to report the last rattle has now disappeared. That was one expensive rattle to fix and truthfully don't know if I ever would have solved it without the front windshield having been removed.

I’ve read that regen braking is disabled on a brand new car until the brakes calibrate. I’ve seen estimates as long as 1,000km for the calibration to complete.

That's correct. Also covered in the owners manual.

Kicked in at exactly 624km for me!

Good to know. I'm planning to do ~1,000km "acceptance test drive" when I first pick up my car at a dealer ~5,000km away from my house. Perhaps by the time I give it back to the dealer to ship to my house, regen will be enabled. Unless of course a big part of the 1,000km ends up on a tow truck if something breaks or EA charging fails me.

I've a strong hunch its how many times you use the brake counts for a lot. After 600km and no sign of regen, I purposefully went out onto a quiet motorway and went from 120 km/h down to 40 km/h with hard breaking a few times.

After the third of those, regen kicked in and has been active ever since.

Interesting. When talking with a Taycan tech at a local dealer, he was telling me that when he does PDI he has to do a couple launch and 60-0 hard braking. I wonder if that’s something the dealer added to calibrate regen? He was telling me this explaining why he sometimes cannot finish PDI if the large parking lot next to the dealership is too full.

I wonder how much braking it takes to calibrate, perhaps you can do it in just one hard drive.

I also wonder if its brake system dependent? Is PCCB vs PSCB vs standard rotors all the same or is there variations ?

I think it varies and possibly read something in the manual on that front but equally I may have imagined it.

I think yellow ones require max speed.?

I suspect it would be. I also know the brakes self-calibrate when charging - they very slowly close and open. It's done after starting of a charge, probably because it gives a high probability that the car won't move for the next 10 minutes or however long it takes to finish the calibration.

Sounds like more of "bedding the pads" than anything else. Not quite sure why the brakes are so mediocre in the Taycan, especially when in the wet.

He’s probably trying to do a quick bed in of the brakes and just transfer some pad material to the rotors, but you should never do a full stop when bedding in brakes, and if they’re PCCBs, the bed in is entirely different.
