MCU with Bubbles

[FlexD]

Good morning, everyone -

It has taken two years to fully develop, but my beauty is in need of a new MCU. The bubble is starting to interfere with the buttons at the top of the screen. Does anyone know if the new MCU can be retrofitted to a 2013 MS? I have delayed getting it done in hopes that I will receive the new MCU. An help you can provide would be greatly appreciated.

Thanks in advance.

My understanding is that without major dash surgery, you cannot replace an MCU1 with an MCU2. I believe it has to do with the instrument cluster being independent vs. driven in one version versus the other. So you'd have to replace both MCU and IC to switch versions.

You'll have to replace the MCU1 with another MCU1, however I know the current MCU1 is much improved (cooling) over an older edition.

I have a 2013 MS 75 with MCU2. The previous owner had it replaced in 2017 along with battery and drive unit.

Interesting. Thanks for the information.

@PWlakewood do you feel it is more responsive? I'm hoping it's the same price to upgrade to if I am able to make the swap. If not, I will have to think more about making the upgrade.

 

[PWlakewood]

Im not sure if its more responsive since ive never used MCU 1. From what the mobile tech told me yes it should be more responsive.

Have you actually verified this? MCU 2 first started being shipped in March of 2018 not any time in 2017.

Mobile tech is who told me that is was mcu 2 and it has LTE otherwise I dont know how to tell otherwise

Go to JSFiddle from the browser in the car. It will explain the values and show which version you have.

.net or .com

Ok and once there what do i have to do?

I have a 2014 P85. I had the same problem, bubbles at the top of my MCU. Palm Deserty service center replaced it with a new one. not sure what needed to be done to to make it compatible, but it works perfectly. Good luck with yours.

With bubbles, if under warranty, they will only replace an MCU1 with another MCU1. My MCU was just replaced and I specifically asked them to upgrade it to an MCU2... and well.. I got an MCU1 (albeit a later revision).

 

[PWlakewood]

and what if you have LTE? Does that mean MCU2?

 

[tyson]

Go to teslamcu.xyz ... somehow the link got translated to show jsfiddle. no .com or .net or anything else. It will tell you what version you have. Although I can tell you that if it was done in 2017 it's a V1 since V2 came out in March of 2018. I have an ~August 2017 build and it's MCU 1.

LTE means nothing. It's been on the MCUs for years. It's also available to all MCU1s as an optional upgrade.

 

[PWlakewood]

ok....Looks like MCU 1. Not sure why the mobile tech told me it was mcu 2.

Just curious, your post and the signature say you have 2013 MS 75? Looks like 75 KW came out in May of 2016.

They lie a lot... my Sales advisor told me my inventory MS 75 was uncorked but I knew it wasn't since the cut off date was june but my car was made in march. I also confirmed with the head office

It was upgraded in 2017

 

[Droschke]

It was upgraded in 2017

Interesting. Thanks.

 

[PWlakewood]

Interesting. Thanks.

The SC rep was shocked to see that the previous owner actually paid for the upgrade
