$2700 to fix MCU. Might DIY, but how much to reprogram new unit?

I think we are on drivetrain #5 and it is now that one clunking intermittently, so maybe we take that one back in. We are on battery charger #2 and battery rebuild #3. We had most of the upgrades (wind noise on the door windows, etc). We had a left rear door handle start to go bad, took it to the shop and they fiddled with it and wanted to replace it, but afterwards no problems so we did not replace it.
Oh, and rear seat belt retractors replaced. These are all issues covered here in forum posts.

Holy crap! What year is your car? I've only had 2 drive train replacements but mine is clunking again.... Did they replace any of yours outside of warranty? I am also on battery charger #2.... still battery rebuild #1 (contactor replacement technically)... I also have a rear driver door handle that presents but sometimes doesn't open... Guess that wire is starting to come loose like I've seen on some of the forum posts... I really think these are items that should be taken care of by Tesla outside of the 50k/4yr warranty. They are obviously defects and if they want folks like us to ever buy a 2nd Tesla there's something to be said for keeping your early adopters happy. 2013 11k VIN here..

So the car won't start. The screen seems to function fine and we made the additional error of hitting Valet mode and cannot get out of it. Maybe we disconnect the battery and it will reset. We cannot put it in tow mode either. The shop needed to close so we gave up for the day.

Do you know your drivetrain revision letter? (Should be on the paperwork from the last drivetrain replacement, it's the last letter of the drivetrain part number.) So far I haven't heard of any problems with the "P" revision, so it would be good to know if you have that revision vs. an earlier one.

Have you had battery pack problems since the inconel main contactor was installed, or only before that?

Best of luck with the MCU. I'm expecting this to be the failure point on most of our cars, so you're the canary in the coal mine, as you were with all the other car problems...

So I also hit the valet button and now can't do anything at all now. Henry, the Tesla Specialist at, Autobahn Auto Dismantlers in SoCal put me in touch with a guy named Alfredo that buys salvage Teslas and puts together race cars. He gave me some great advice on getting the brakes released and then I will put it on a flatbed and drop it into the arms of the Burlingame service center. Alfonso also said that there is a guy in Berkeley (@Ingineer?) that can reprogram it remotely.
 
So I figured out how to send him a pm. I also got his email and sent him a note that way. The shop doing the MCU installation is in South San Francisco about 6 miles from the Burlingame service center. The tow should not cost too much, but I don't know how backed up they are until I call tomorrow.
 
I was actually referring to an earlier post in this thread but I am charmed that you found that one from a year or two ago.

At that time I was sorely disappointed by the lack of support for fleet buyers and people like me in the livery (limousine) trade that were taking a chance by putting a Tesla into their fleets. Not only were we enthusiastic supporters of electric vehicles, but we were providing the public an opportunity to experience what we felt was the future in terrestrial travel. It was certainly hard to get a test drive in a Model S in 2012 without being a true "prospective buyer" but we (livery providers) had the opportunity to put 5-10 people a day into the back seat of a Tesla and show, very early on, what a game changing vehicle the Model S was. We made 6-panel folding brochures, put business cards from the store in Menlo Park in the car, made promotional postcards, blasted 20,000 emails to our existing customers worldwide, we even had refrigerator magnets made with a picture of the Model S and our own logo. We shot video, staged photos etc.

What we wanted from Tesla in exchange was some sort of preferred service similar to what other car manufacturers provide the livery industry. With the established manufacturers, we get promotional materials, photos, videos, advertising copy in a media kit, we also get extended warranties, prioritized service and or, for example with Ford, a separate "commercial only" service center. In my pleadings with Tesla I promoted the idea that the livery business could be a parallel sales platform and that they should help it promote the vehicle and support our efforts with extra help to make sure that the vehicles stayed on the road and to minimize our risks and downtime and provide a public appearance of reliability and trustworthiness.
Unfortunately, they refused any request for help or special treatment. When I asked for what is called "B roll" or copies of Tesla's own stock promotional videos for use in our company's web videos, we were told just to go out and have our own videos professionally made. When we wanted to put softer shocks on the rear of the car, we asked for the model # or even the stiffness rating of the stock rear shocks, they refused to make the inquiry. I asked for priority delivery so that our promotions could begin right away and if they took off, we wanted an ability to add to our fleet immediately so that we did not burn the market that we had created ourselves. The response was that we had to purchase 10 or more vehicles to be considered a fleet buyer. So we spent $50K in deposits on 10 more cars to prove our intent, I guess our word or standing in the trade was not enough. When our "special delivery time" arrived after making the orders for the 10 more cars, we got our car about 10 days sooner than another single-car buyer with the next order number. So much for the $50 large! Where would I be now if I just put the $50k into Tesla stock instead....... There are so many more examples.
So when the charger failed 5 days after the 2nd battery replacement and we were told that the charger was not under the drive train warranty, It's an electric car, how can the charger not be part of the drive train!? So I wrote that post. Within 2 hours of me posting here it the fleet sales manager that had been so difficult to work with called me and told me to take it to the service center and it would actually be covered under warranty. The squeaky wheel gets the grease.

The Burlingame service center can take us next Monday morning. Still waiting to hear from ingineer. With the help of Alfredo from SoCal we got all the brakes unlocked using a booster battery so the car can roll out of the shop and on to a truck. We are buttoning the baby back up now. Disconnecting the 12v battery did not do anything.
 
So the whole thing fell apart. When we took it to the Tesla service center, they refused to work on it and said the part was "restricted" and cannot be installed then and serviced by Tesla. Last week I asked what it would cost to program the MCU but did not tell them I was planning to install another one myself. What is worse is that when I checked in with Alfredo, the guy that the seller recommended, he said if someone else like ingineer does program it, the car will likely be blacklisted and Tesla will no longer service it. I can also get some sort of personal categorization that would limit or prohibit servicing. So we are towing it back to the shop and putting the old screen back in.
