That happens to me all the time. Often it’s a pebble that gets stuck between the brake rotor and heat shield. Makes a HORRIBLE grinding noise that can change with steering angle and/or reversing. Jack up the offending corner, take the wheel off, and bang/pry around the heat shield a bit...

really? that very same service center charged me $15 to reprogram a set of keys purchased from eBay. oh wait, maybe that was Palo Alto? they even tried to program a 3rd key from a model x with my model s, even though they said it wouldn’t work (but they tried anyway for fun)

I'd just pop it back in myself...

Is it possible that they're shipping units with lesser "quality" cells? Like ones that have greater imbalance or such? Kinda like binned CPUs... Seems like a great way to salvage packs that might have failed QA. (presuming they have QA)

Thats an interlock error, but you'll need the other errors too. Have you gone into service mode and looked?

In my case, the rear drive unit was replaced under warranty, but it was likely only tangentially related. The cable to the front drive unit did have a short to the shield at the front connector. That one plug is noticeably floppy and wiggling it makes the short intermittent. So far replacing...

You sure about that? The gen 1 FJB has the DCDC converter built in (that weird shaped one). The gen 2 is up against the firewall/bulkhead and is separate to the DCDC. I didn't think either of them had wires to the front motor. In fact, didn't the gen 1 predate dual motor cars? Ahh, I think...

I bought these: https://a.co/d/d5hFiuQ The 25 was pretty much as cheap as 20 (was $30 then, seems to be $35 now), so I figured I'd have a few extra. They're great. I highly recommend them, best $30 spent on the car -- I've had soooo many of the crappy stock ones fail. I also like the looks...

Hi folks, sorry for the disappearance there for a bit, and thanks again for the help. An update: On Friday, I had a tow lined up through AAA, but they took 4 1/2 hours to get there despite them saying they were "10 minutes away". Yeah, dude, I see you on your little map driving AWAY from my...

Yep, definitely suspicious of water/coolant intrusion back there. Since I'm still under battery and DU warranty, I'm comfortable having relegated the problem to the back of the car. I've ruled out the BS about the front so now I can defend my "no, I'm not giving you $1600 to NOT fix it"...

Well, I couldn't find a megaohmmeter on short notice, so what I did was disconnect the HV pair that go to the front at the rear junction box under the seat. Closed the rear box back up and turned the car on. Same result (and no add'l errors). To me, this means that since the HVIL loop is...

Yep, my thoughts exactly. I did inspect and reseat all 4 plugs on the FJB this morning, all clean, all reseated well, no change. Loud sound from compressor wasn't at car startup, it was just sometimes. I'd often notice it about halfway through supercharging. Could be totally unrelated...

Thanks Howard, yours was definitely one of the many many threads I pored over for knowledge. And yes, it does sound like only the precharge contactor is closing, definitely not the full contactor. The HVIL loop is definitely intact because the car definitely knows when the first responder loop...

Hi all, I'm in need of help. I have a 2015 P85D (March 2015, P69xxx) that has recently gotten the dreaded "Unable to start vehicle – Service is required" error. QUICK TL;DR: iso faults, BMS_f151 & BMS_w142, towed to service who said battery coolant heater, but then it drove, but then errored...

no one knows? just in case I was confusing: I have a 90 mph autopilot limit. Nine zero. if I update, will it go DOWN to 85?
