I created my own precharge problem in this case. While servicing the pack, I capped and stowed a lug that goes to the B- terminal and forgot to reconnect this after sheet reinstallation. Ideal fix!

I believe (with limited knowledge of the precharge circuit) if it were to fail open, then the system should never reach precharge voltage (opposite of it reaching precharge too fast).

@thefortunes - thanks for the reply. I did check that FET with continuity and didn't find any pins shorted to any other pins in doing so.

Hi all, Wondering if anyone has more info on how the precharge system of the Roadster works. Long story short - I popped an ESS sheet fuse while accelerating a few months back, replaced it, and am now working through precharge errors (BSM: precharge too fast at t1 ID:275, and BSM: V_ess too...

Yes agree with Steve, there are definitely four unique wheels for 1.5 & 2.0s (as well as 2.5s). The photos @drewski linked to could be from a car that only got one direction of spokes on both left and right sides. Every 1.5/2.0 that I've seen with forged wheels has had them all pointing forwards...

Nice! I remember browsing that site. My car came with every option (carbon interior, carbon front spoiler lip and intake vents) except for clear carbon rear spoiler and clear carbon hood vanes. I shelled out for the rear spoiler ($1500 I believe), but couldn't swallow the $4000 price tag for the...

Ah, I never noticed the marking on the inside of the rim. When you say 'when Tesla installed them' - did your car have the non-forged wheels to begin with? My car is one of the first few 2.5s produced according to rumors and VIN, and it was assembled with the wheels in the wrong direction. I...

Very cool, will be watching. Question - have your wheels always been in that orientation (spokes pointing forward)? I have VIN 965 and my wheels have been that way for the life of the vehicle, but every other 2.5 that I see has the spokes pointed backward. I always thought I was the only one!

I'm on H2O as well, works well. Does use ATT's APNs though, so hopefully won't be affected as well in Dec.

I didn't thoroughly pursue a rebuild with Bilstein as I would have had to remove my front struts and have my car up on blocks for some period of time. I eventually went in for service and had Tesla replace the front struts at my expense. How many miles are you at when symptoms occurred?

There are two *very* low-mileage, black-on-black, Roadster Sports on eBay at the moment: 2.5, 6753 miles, $85K: Tesla : Roadster Sport 2.0, 2121 miles, $75k: Tesla Roadster Sport | eBay The 2.5 is from a dealer in Texas who seems to move quite a few Roadsters; you would probably be able to...

Matt, thanks for all of the details! Glad to hear you've finally got a silent front end. Based on what you're saying...was the issue somehow related to the remote gas cylinders of the front shocks? I'd be interested in narrowing down the cause of failure (assuming it's the same as mine) in...

Thanks everyone for the suggestions & advice. I'll explore my options and update. If anyone else has datapoints on these particular shocks and their lifespan I'd be interested.

Yeah...the downtime is the biggest antagonist to trying to handle this myself. Tesla has the parts in stock but we are talking about $1300 per shock plus labor. And I'd probably want to replace the fronts as a pair, and there's no guarantee the same thing won't happen to the rears. Hopefully...

Nope...car hasn't seen off-road or track use (and I'm a light-weight). Really normal driving, and I'm careful to avoid bumps/potholes. I agree this seems unusual... - - - Updated - - - Thanks wiz and rdstr for the rebuild advice, and insight as to what might be going in internally. Unless...

Hi all, I own an early 2.5 Roadster Sport with just under 10k miles. Recently, I noticed a 'knocking' noise from the front passenger-side wheel whenever that wheel encountered the slightest bump or inconsistency in the road. The noise was faint at first, but quickly worsened after only a few...

For me it is named 'Open Vehicles' in settings>notifications, and with the OVMS icon. Even if it was denied use of PUSH notifications, it should show up *somewhere* on the notifications list. If under the 'do not include' section at the bottom, that could justify why no notification pops up...

It is listed in notifications for me...running iOS 8.3 and app version 1.6.5. The way an SMS to the module is relayed to the app is via a banner notification containing the SMS. I confirmed that with notifications for OVMS disabled, there is absolutely no response from the app when sending a...

If you're running the app on iOS, how about settings>notifications>OVMS? Make sure you have notifications enabled.

Not sure what CIPSHUT means, but I've come to associate it with frustration, as that was included in the *many* SMS messages I received during initial setup of my module with AT&T before switching to H2O. Turned out to be an incorrect APN that was hindering GPRS connectivity. For H2O wireless...

I was going to recommend checking that parameter 3 (notifications) is set to SMSIP, but I just confirmed on my setup that even when set only to SMS and rebooting the module, a notification still comes up on my OVMS iPhone app when I send a random SMS to the module. Maybe check that you have the...

I had a similar experience recently when logging into H2O's website (requiring a code issued via SMS). At the time, my GPRS link seemed to be having issues...I could SMS to the module and received a response, but the app couldn't connect to the module. I planned to troubleshoot by pulling the...

DFD, really like the CCCF tail-light surrounds. Can you tell us who made them?

Got mine a few months ago as well...it came with the standard 2.6.5 firmware but not Roadster-specific. SMS commands for Cooldown would simply pop up at the top of the app but I never got a reply or was able to set Cooldown parameters. The Roadster-specific firmware is here...

Hmmm...interesting. But I have had the car cool itself down a few times (independent of ACC) while charging on 120V/15A...I recall this happening when the pack was above 30C and when charging reached 90%SOC. It was as if the car didn't want to cross over into a higher SOC with the battery at...

Tried this a few times over the weekend...SMS'd the car just after an hour of charging (once the Cooldown window was over and it switched into standard 15A charge): STAT? yielded: 06:04:29 Standard - Charging 114V/15A Full: 535 mins SOC: 78% Ideal Range: 140 mi Est. Range: 113 mi ODO: 5526.2 mi...

Update on H2O wireless: been using it for about a month and it works great! Thanks for the recommendation, Tom.

Has anyone had experience using the Cooldown ACC feature with a spare mobile charger (15A/120V)? I've confirmed Cooldown works with my 40A UMC, and it works great in multiple locations. But I haven't been able to get Cooldown working with my SMC in two different locations where Cooldown works...

The base DataConnect package is 250MB/month with no SMS. I just wanted it in a hurry before the holidays and went to the AT&T store. Thanks for the tips on H2O Wireless, I think I'll give them a shot.

Just wanted to note that if you obtain a DataConnect SIM from AT&T, there are apparently different APN settings from GoPhone or their other services. Despite AT&T repeatedly telling me that the correct APN name was 'WAP.CINGULAR' with no username or password for the DataConnect plan, and my...
