Hello, I'm wondering if anyone can suggest a place where MCU1 units can be repaired. I recently replaced the battery at a third-party Tesla shop, but my MCU failed unexpectedly. I'm aware that Tesla has a recall open for EMMC repairs, but I am not considering this option because my Tesla is...

very interested, sent DM

The main contactor will not close if the 12v battery is low. Replacing the 12v battery is a good start, after that just plug it in and wait, it might take anywhere between 4 to 6 hrs for the HV pack to start getting any charge.

Here is my version

Yup, mine is #2077

What's the code of the error? If it's for the HV pack, then It is not going to be an easy fix, you would have to drop the battery since older versions have a fuse box at the top right next to the Battery penthouse.

Was wondering if there is an update to this.

I'm not an expert but would like to share with you my experience. I had the same issue with my Tesla. It all started like this, the imbalance was causing the battery to die on me with 10 miles left on the dash, it was getting worse and in three months I got the BMS029 error. Tesla probably won't...

Short follow-up on my issue. Had to perform a "surgery" as per instructions seenon one of the Rich Rebuilts Utube videos. Had to drill the hole and use the telescopic camera to be able to hook up the secondary latch from inside the frunk compartment. All in all, appr. 45 min. operation.

Thanks, but this would nor work with MS 2012

Yup, looks very similar to the problem I'm dealing with. Thanks for pointing out this video to me.

no, it does not have the release pull inside the car, and I can not access the car anyway. Do you mean the plastic underneath the front end of the car?

The exposed terminals are not working. To be exact, the positive (red one) is not working.

That's the problem, the exposed positive terminal is not connected to the battery circuit, and they probably missed connecting it while assembling the front of the car. Trying to find a solution for how to manually open the frunk.

Both are second-generation latch system. Won't work in my case. Thanks though

Thanks, but mine is the first-generation frunk latch system, won't be possible to do as per video.

I experienced exactly the same situation. Tesla-certified body shop kept my car for 4 months often forgetting to plug it in at a very low state of the HV pack, eventually while still sitting there received the BMS u029 error. Of course, they deny any liability for their actions. I got my car...

Need help, 2012 Model S, HV pack is dead, 12 v battery is dead, and the positive terminal is disconnected thank you Tesla certified body shop. Can't access my car or open the frunk.

Is this still available?

Would like to keep the Signature model, and it does have an air suspension. Still wondering if the battery from Dual motor vehicle will fit my RWD.

Hi, I'm impressed wth an update you've done to your Tesla. I currently own a RWD Model S and am on the market for a 90kwh battery. Was wondering if I can potentially procure a battery from the Dual motor Tesla or it has to be RWD just like mine is?

My battery pack just recently failed due to a big imbalance in the pack of over 200 mv. I'm looking for a used pack and was wondering should I consider HV packs from dual-motor Teslas MS MX? I was told a battery pack from dual motor vehicle has a slightly different lineup of bolts at the front...

do you know if a config change is doable in Dev mode or requires additional equipment to be involved? Thanks

Hi, I own a 2012 Model S Signature P85 and having the same issue with the battery as you did, it failed at needs to be replaced. I wonder if you could share with me how to redeploy the software. I have a module that allows me to switch the car to Dev or Factory mode / redeploy the existing...

Unfortunately, in most cases this will require battery pack replacement. I experienced it twice

Beautiful car, I’ve heard Open pilot can’t be installed on 2012 Tesla?
