Has anyone collected the certificate and dump from an MCU and attempted to flash to different MCU?

OK this will most likely be the final post to this thread. It is really the lesson for anyone else doing or thinking of attempting this. Ultimately it all comes down to how much you want to spend. But I had a reasonably solid figure in mind that I used to keep myself in check. I think everyone...

So I finally got into the penthouse and did some battery analysis today. There was a hint of moisture inside, condensation rather then puddles. However after testing the pack was holding 354v nominal so that's a good sign 👌 Now I can carry on with cleaning up the body control modules and car...

I had a bit of a hold up getting into the penthouse with the 5 lobe torx sockets. Turns out this isn't an item I can source easily in NZ. Funny enough I was just watching that video and it really pulls things down to the bare bones (literally) but very educational in its own right also.

I'm sure it would work well for that. Opportunities everywhere!

I'm testing out the HV system tomorrow with someone who is far more qualified then me. Infact he was the first person in New Zealand to build a custom EV. I didnt want to be the first person to be fried from an EV. The car was a BMW hatch body with an electric heart. Nor did he use a conversion...

Thanks for the Insight and knowledge. I too have to remind myself to be realistic with what I'm dealing with. The components I'm most worried about are the ancillary items such as electric windows electric seats etc. And anything else that can't really be opened and cleaned and assessed

The water was definitely fresh. The car was off at the time it was flooded. The first attempt to power on was me after 3 months of sitting. That's when I cooked the vcfront. Any particular solvent you found that worked better then others?

I did think seriously about this. But many would be thrown off by my kiwi (New Zealand) accent.

Thanks for some direction. It is always welcomed! Do you have a link to the process of depowering the HV and checking? I would rather have a step by step path to follow, then making my own assumptions based on snippets of other information I have found.

A few more runs with the power aided cleaning gear then it's on to the manual elbow grease.

Quick update, everything has been removed from the interior and have power washed and vac'd up most of the mud. The hardest part was removing the seats. Couldn't move them back or forward so some of the bolts had to cut off.

So my basic forward plan is as follows: > Disconnect HV system > Remove most of the interior. Will stop at the dash somewhere > Remove vcfront(done) vcright and vcleft. The security model will come out with the centre console. > Remove car computer (MCU) > Any others that I've missed? Next...

Why? why not! There have been plenty of examples who have undertaken similar projects. There's no shortage in opportunity.

The next best thing is a dehumidifier and that will be getting plenty of use.

I think the deal breaker will be if the pack is no good. Other then that I don't see huge amounts of cost other then my time.

In this case basically anything electrical would have to swapped out. Getting it re-registered is something I am not chasing. In saying that I have sent the proof of ownership documents to Tesla and they were happy to transfer me ownership to the app. I have ordered new keys and hopefully get...

Now I don't consider myself as mentally impaired, however I'm also not one of Elon's senior electrical engineers. But once I smelt the burning electrics I knew I had to actually do some research and figure out how these things worked. Lucky tesla has let go of the reins and allowed access to...

I forgot to mention that the car also has no keys. I could gain access to the interior of the car as the back window had been left down, so after watching a few episodes of MacGyver I was able to open the front doors(emergency release). After a few days of digging with a kids plastic Shovel...

The goal is to bring it back to life. Life maybe somewhat different in its reincarnation, but ultimately I would like it similar to how it left the lot.

Hi team, After going through a heap of threads I have decided to post my journey. Hopefully with the help of multiple minds and experience/expertise I will succeed in the end! I acquired this 2021 Tesla Model 3 Standard range plus (single motor) here in New Zealand after a cyclone. The car was...
