Tow Required from Supercharger Station (Error Code: DIRER_a149)

[DoberManPin-Sure]

Pulling away from charger, my monitor started flashing red and alerted me to “critical issue” and driving was limited to a snails pace. Called roadside and they said a tow would be required. I’m waiting now. Tow truck driver is a CT owner too, so some degree of comfort there.

Really disappointing, but better here than on the freeway I was about to be on.

Anyone have experience with this one?

UPDATE: Literally seconds before the tow truck showed, I put the CT back in drive to see if I'd be able to drive it onto the flat bed. When I did, all the error messages were gone, full power was restored, rear wheel steering worked and it seemed to be back to normal. After a few minutes of talking to the tow truck driver and with no error messages reappearing, I opted to drive it the 11 miles home. My wife had come to get me and the tow truck driver was headed to the same neighborhood, so I had ample back-up in case the issue reappeared. I drove way slower than normal and used FSD most of the way. I made it home without incident. I'll be getting it into the SC ASAP though. I hate this first basis for insecurity and hope I can regain the faith.

Let us know what the SC center. As a 2x flatbedder, hang in there. You’ll regain confidence soon. There’s really not a ton of things to go wrong that’ll leave you stranded. Just some kinks to work out.

Remember for the earlier Cybertrucks, some had unofficial preemptive inverter and motor replacements

I had kinda the same issue. PCS (Power Conversion System) failure and replacement. CT died on the charger. Took about a week to replace. Same error. Looks like a redundant problem. Several others have had the same. Remove the plastic hub caps when flatbed towing. Too much pressure on the hub caps from the straps. They can definitely see the error codes/log.

I thought my June delivery and just under X20000
VIN meant I dodged some bullets. My service appointment for the spare tire install just got a little more serious.

I picked up my CT in September. The PCS looks like a computer mother board. It was pretty embarrassing, the truck was completely dead, couldn’t even get to the inside until the tow truck arrived and we got power to it thru the bumper 1st and then thru the frunk.

Sorry to hear about your woes, @DoberManPin-Sure. Hope it's something relatively simple, and they get you squared away pretty soon.

If you check Service Mode, you'll likely get a much more nuanced view of what might be going on.

You and I are in the same VIN range. My hurdle came on day three of ownership. They ended up replacing my rear drive unit. Hardest part was waiting a few weeks for my Service Center appointment; then the week that they had it.

My truck has been perfect since. Trust will come back with time and miles.

Best of luck!

Browsing through these faults, they all appear to be related to the oil pump(s). There is a 48v pump located in each drive unit controlled via LIN. When you first begin rolling the vehicle forward (or back) the oil pumps are commanded to spin up. During start up, current, stall current/motor response is monitored for each. One of the pumps likely indicated some sort of failure.

If you’re interested in learning more about this before your appointment please PM me and we can arrange to have a deeper look remotely. The faults each carry a payload of additional data (see attached) that should be useful for diagnosis. With faults set for all three pumps I find it hard to believe that all three faulted at the same time. For the rear pumps, there is a common ground which could result in faulting but since that ground is used by other consumers I don’t suspect it.

FYI, I recently came across a bulletin about drive unit oil levels. It seems as if some of these were under-filled during vehicle production. The bulletin requires the technician to record how much fluid was needed to bring the units to the full level.

FWIW, we have found a number of Model 3s with low oil level, and these require actuation of the pump during fill. Many of these you can hear when the pumps are running (aeration).

Yeah I agree, there will be bumps in the road! BTW…. We are also big Doberman and also Min-Pin fans….

Is R right and L left?
If so, it seems like it might be a momentary comms/ startup issue, especially if the DIF error is the power feed for the second rear oil pump.

Faults are set for all 3 drive units. It’s not uncommon for Tesla to trigger a bunch of faults when only one issue surfaces. I looked for anything common that could fault all three and the only commonality I could see is the shared ground for the rear units. At this point, loading the faults up in periscope is the next step in isolating the problem IMHO.

 

[DoberManPin-Sure]

I greatly appreciate all the great feedback, generous offers of support and kind words.

I received this message from Tesla this morning, which is more uplifting than concerning, but a bit of both. Glad it’s not mechanical, but the glitch is still troubling since we rely so much on software.

Thanks again!

P.S. Props to Tesla for working this issue over the weekend after I sent a message about it via the app. Look forward to the update once I’m home. Drive in to office was issue free.

Thanks for the update, be sure to ask about the fluid level check to see if you need to take any action.

And can you share with us what version you were running when the fault surfaced?

Thanks,

Scott
