FYI, I work with embedded Linux systems testing them and looking for failures. My expertise of 20 years is with Unix embedded systems. At my current company our test units have no power button and we do as part of our daily tests abruptly pull power on a running system, so no clean shutdown...

Linux will do an FSCK check of the filesystem and automatically fix things if needed. Only bad thing of pulling the plug on an OS is that you can't guarantee your data will be written and that same data will be there after the reboot sync memory wasn't flushed and synced to disk.

From what I know about the battery cooling threshold, those are the same for the 1.5 / 2.x's. However what is different is the PEM cooling thresholds. The upgrades the OP discussed are with the blower upgrade on the 2.x's, the upgrade gave them a dual blower/fan with a single motor. This...

If you can see pressure readings in the VDS then it appears the TPMS sensors are functioning. I believe you can take the Roadster to any tire shop and they should be at minimum be able to read the TPMS battery level. I'd check that out first, but don't hold me to that. Its a "should" that...

12 miles is low, I'd expect it to have kicked in a charge around 20 at the lower limit. If you don't live an a climate where its extremely hot or freezing I honestly feel the best way to put the Roadster into storage mode is to pull the ESS service disconnect. The battery holds up for a long...

The rat took it up there. It has chew holes in it plus it chewed on my CD case. My friend said these varmints like to sit in places that are warm at night, so my Roadster was parked in the front of the house where its sunny during the day. It holds the heat though the night so these creatures...

So today I checked the fuse block by the passenger side that's inside the cabin, all fuses appear to be good. In doing this I found one of my yellow shop rags tucked up into the under dash area by the foot-well, by the VMS box. I pulled it out and its chewed up as well as rat droppings fell...

Agreed, the 1.5 TPMS thread(s) and these solutions were from my hunt to find an affordable alternative to the $400-$500 Tesla priced one which we were stuck to. There's no need to go any other route then Tesla for the 2.x's since they already are at an affordable price point. While we're on...

I didn't have any rattles or creaks to start with but I did have a very hard and harsh ride whenever I hit bumps or uneven surfaces. Switching out the stock shocks for Nitrons helped, but it was the combination of both a good set of shocks / springs combined with the spherical bushings that...

I did pull the lower PCB out, had to do that to tighten down the loose HV+ line and also to inspect that R4 solder point. The solder point on the lower portion of the PCB looked fine. All of the solder points and lines look good as well. Interesting enough the bottom of the lower PCB board is...

Buttoned everything back up after tightening down the loose lug, still get the same errors. Note that if you don't put on that external ground in the HVAC 400V Control box that the Roadster will immediately fault out, plain old yellow fault on instrument panel. Nothing shows up on the VDS...

In taking out that PCB board above I found the far right HV+ line or lug (gold) is loose! Possibly vibrations took its toll on it, backing it off and then when I hit that bump in the road jostled it enough to cause a spike down the road. Still pulling the board out but that's another oddity in...

So after talking to my friend, that resistor / solder point from the 400V control box lower PCB (red circle location) it appears a little bit suspicious. He said it appears it got hot there and recommends re-flowing the solder at that point. I may try that this week and see what happens...

Here's some of the pics of the opened HVAC 400V controller (top and bottom PCB), the resistor that has the odd solder pattern as well as pics inside the PEM showing the fuses.

Will do when I get the time for the pics. So the (V_ess too low during precharge, T2) is an error code indicating that there is too much capacitance on the High Voltage Bus or possibly a leakage path that is drawing down the battery during precharge. While I had the time I popped the PEM cover...

To be fair, the poster M808 does have a LinkedIn profile associated to his profile: (https://www.linkedin.com/in/mikemoore01) I don't see anything related to resale or connection with DFI, I do see some technical background experience with aviation and also that he's a pilot. There's no...

Remember that the battery pack cooling has priority over you when it gets hot out. When you hear the AC cycle or know its on but its not getting any cooler inside I'm betting the battery is getting the chill. Julie, did you take any pics of the error messages? That's what is helpful to debug.

Took the 400V controller out. Unbolted the top and started to do some of my own tests. There are two PCBs. One housed on the top where the non HVAC connector is connected to, top PCB has 4 large capacitors. Top PCB of the controller is the one with a heat sink to the fins of the top 400V...

I haven't had the chance to remove the 400V controller. However I was able to get that fiberglass rear body filler out above the battery pack. I took pics and will post when I can get the time. There are three clips that are pressure clips, one on each side of the window and one in the...

Looks like I'm going to pull out the 400v controller and have my hardware engineer begin doing some tests with it and see if we can identify an issue, possibly fix it if possible. Interesting tidbit and coinicidence about the wet day connection.

Mark, where the VDS error messages different and/or any additional messages displayed when it blew out your ESS fuse?

Thanks everyone for the input! I honestly do keep water away clear of that silver 400V controller in the front and don't recall getting that box wet this last time around. I would think if I had water intrusion in that controller on in the PEM that the system would not have allowed me charged...

So my Roadster ended up cutting out this week. Roadster has been sitting for months at 60% SOC. Made it into work fine which was 35 miles. About 8 miles into the trip back the Roadster's power shut down and I ended up with the following faults below. I did a key reset after waiting 5 mins...

Curious, did you ever figure out the root issue?

Don't get your hopes up, the Xenon ones also are prone to peeling. Put covering over it, cheap insurance.

Only thing I worry about is clarity through the glass with "something" over it. Glass is the purest thing to see through without any distortion, throw some plastic film over it that gets hammered by time and UV rays and it starts breaking down and becomes distorted. I like the concept...

If you shut power down from the PEM and well informed you can do the change yourself. Don't do it live, ever. As for carrying spare fuses, I would if and only if they've blown on me before snce there was an obvious current spike that occurred and never resolved nor the source identified. It...

Only way to find the authentic answer to your question is to call the Tesla Service Center yourself and ask as well as to report back so others are informed.

^ Exactly ^ Its insane and sad how shops can charge their incompetence to the customer's wallet when the customer was the one who suggested the solution. These are professionally trained experts so they say...

What fuse costs $400? Must be gold plated..... :)

Flashing lights with audible bell is signal to you that the alarm has been just activated, the honk of the horn when the fbb is pressed a second time is the confirmation that the alarm has already been activated (which I believe the lights also flash). The alarm is also set and activated via...

nope

You have to find them used, Eric is no longer an active member on the site unfortunately. There were only a few of the full soft top conversion you were talking about and looking for. Jory's was the only one I ever seen placed up for sale. I have the slim one and prefer that honestly. The...

Great job Daniel! Was a fun and interesting journey and glad it ended well. Also nice seeing the honesty from the Tesla Service Center and to report back to you that you didn't need to drop 10k on something you really didn't need. Thanks for putting the time in to document this though.

They're using a typical ISO harness on the 1.5 which VW uses, most likely the same with the 2.x's. Nakamichi CD400 Head Unit swap for the Blaupunkt - Speakers came alive and sound

Annual service is something that can be performed in a couple of hours, especially with the 1.5 and having all the proper equipment and steps documented to do so. The two times I had taken my Roadster in I'd leave it there for a couple of days just so they'd have wiggle room with the techs to...

I think you guys are missing it, you need the firmware to drive the updated 2.x fans/blowers. Its one motor with two fans/blowers. They're driving more current hence why the fans power on and when they get hot, spool faster. This is also the reason why the fan / PEM connector gets melted by...

I believe Nick has a 1.5, however the motors should be the same. Possibly they're driving them a bit differently. Would be interesting to see if another 1.5 experienced the same issues on the same day. The other possibility is the blower setup on the motor. The 2.x's ( with the updated...

Note that these small locks are not security devices by any means, key or no key! Never trust any lock and know that *all* locks can be opened. A small bar with leverage pops them every time or carry a small snipper. What they are and what I use them for are deterrents from somebody just...

All the J1772 handles I've used have a hole below the release button, this is where you place the padlock on after its connected. I'll try to get pics of my combo lock when I get a free moment...

Also read up on fixing it, there's an instructibles article that shows one being fixed by replacing the aluminum foil dots to re-enable worn contact points. You can buy these dots online: DIY Remote Control / Key Fob Repair Kit - - Amazon.com And online videos and such regarding debugging and...

While we're at it. I carry two pad locks, reason being is that one time I had someone disconnect the J1772 adapter while the car was still charging. I usually don't lock it in case of someone's dying need of a charge, however there are some anti-EV folks who want to play games and EV owners...

You don't need to disconnect the 12v battery just to remove the seats. Just know that the seats are a puzzle taking out, hand brake is attached to the driver's seat and the passenger seat front right bolt by the door is tricky and is best done with a special / modified too. But do-able with a...

If you're not familiar with electronics and how to source components, take it to a quality electronics shop or have a computer hardware engineer friend if you have one open it up and take a gander. You might be able to first test the button to verify that indeed is the issue, or trouble shoot...

I use a small combination lock, the size of a luggage lock. I prefer a combo lock system for that its one less key to loose or leave behind that will keep you locked out of your own stuff. The key, no pun intended, is that the lock of course fits through the hole for the lock of the can and...

I don't have a 12v battery since I have a 1.5 Roadster and yes you will be breaking the tabs.

If you have a 1.5, yes its an issue due to no tire learning. Why not order the correct size via the Tire Rack and have them shipped to your garage to be installed? I'd rather go wider in the rears than smaller unless you're a hyper-miler.

No duplicate colors? Looks like you all had a blast and nice seeing Doug made it out to this one.

I say keep going down the brave part. I'm sure you can find an answer and solution to all of this. We're all rooting for you as long as you have the patience and volts left in your pack! Thank you for documenting and a pioneer in respect to the PEM.

Thanks for the thread, very informative. And yes that jump is interesting in the 3.0 pack. Think it may be with the pack balancing? You haven't had your 3.0 pack for long correct? They (ESS/Battery packs) do grow over time in CAC as time passes, reach a ceiling, then being to drop. So in...
