GS Technology in Switzerland can service the battery and replace the fuse. I'll send you contact informations via pm.

Maybe simply the 12V Battery starts to fail. If this is the case, press door button, wait 20 seconds until roadster gets power from the main battery, try again.

I don't know if it helps. But there is a company called GS Technology here in Switzerland that can repair your PEM. Maybe it's easier to send car or PEM to Switzerland than US.

A bit offtopic, but I want to do repair my ventilated seats (leather has many wrinkles) at the leather shop. Is there anything to be aware off when removing the seat? Or is it simply power down vehicle (via the menu), remove seat, install, power up? I want just to be sure that there is no airbar...

For how long is your car bricked? if it's happened not too long ago, maybe it's possible to recover. You should contact GS technology in Berg TG as soon as possible. They are anyway the best address for roadster problems in switzerland (also PEM repairs).

No. You still mix up capacity and SOC. 100% SOC is always 4.2V. New, after 50'000 miles, after 500'000 miles. Always. Capacity goes down over time. You have a usable capacity between about 4.2V and 3.5V. When a cell is new you can use f.e. 3000 mAh. Now your cell gets older and degrades to...

*lol*. They could say that for almost every part in the car. Battery dies? "We got the cells from panasonic, so it's not covered".

Hi, What is the option "Reset SOC Params" under "Control" in the diagnostic menu for? I had in the past some strange SOC readings (7% difference, while voltage was perfectly balanced). It fixed itself after some driving and charging. But would pressing this button help when it happens again...

Here a top secret preview of the next software versions:

Yes. And rattle noise of suspension will be fixed with a permanent background sound from the audio system. Great :-)

There are phone displays with similar issues. And some reports in forums that 10 minutes under UV light in the nail salon can fix that (really, google it). Maybe tesla does something similar. A big screen size UV light.

I noticed similar on my roadster. If the battery goes slightly out of balance (0.04 or 0.05 V) then SOC shows a difference between 5% and 7% between MIN and MAX. So it stops on MAX 89% and MIN 82%. After some balancing, voltage difference goes down to normal 0.02 or 0.03V, but SOC still shows...

Today both GPS, the internal one and the alpine unit are still working normally. :)

Hi, My roadster is sitting in the garage for about 6 weeks. I regularly check SOC, just to be sure everything is ok. Yesterday I had this readings: V&T: Vmin: 3.79, Vmax:3.81 SOC: MIN/LIM: 47%, MAX: 55% That seems odd. While voltage show a perfectly balanced battery, SOC shows the opposite...

Patrick, did you buy a roadster or just looking for one?

Hmm... and battery 36°C after sitting in the garage without charging.... something must drawing a lot of power. Or the measurements are simply wrong. Is the PEM and ESS feeling warm if you touch it?

PEM has 61°C without driving or charging? How can that happen? I suggest to pull the orange main fuse to be sure that battery can't get empty. Main Fuse

My roadster showed the error today. Did you get any feedback from service center? Or was it a random error. and never came back?

Hi, I have a european Roadster 2.5 and I have the COC. I can send you a scan of the second page, but don't want to post it here in the forum. Can you leave your mail-address?

You're right. If I had to pay for the repair I would try this, if there is a company that will do it. I think it's not that easy to find one. In my case it's a warranty repair, so tesla is replacing the gearbox.

Is getting parts also a big problem in the US? We have some discussions in the german forum. I'm waiting for 4 months for a new gearbox (because of a bad bearing), and have still no expected delivery date. Another forum member is waiting since september for a new PEM.

My car is the service center since begin of february because of a vibrate/humming sound at low speed. They replaced the gearbox, but wasn't fix the problem. Then they ordered a new motor and gearbox again (don't know exactly why, seems something was not ok with the first replacement) from US...

Hi Austrianer, How long you waited for the spare parts? I'm waiting for more than 3 months for a new motor and gearbox and still no expected delivery date.
