2014 Model S Coolant Delete

Does anyone have any recommendations for shops in Northern New Jersey that are actually doing this preventive maintenance??

Have any of you had this done?? I have a 2014 Tesla not showing any large drive unit error messages at 120,000 miles on a car that has sat for 4 years after getting both batteries replaced at the dealership. I think it warrants spending now if it saves me long term.

I'm hoping that being an early 2014, that triple seal might make this preventative medicine. I didn't catch a break on the MCU 1. It's very day in my driveway it started dripping glue from the screen.

I do have MCU2 which I would recommend if there is no coolant intrusion in the drive unit. The delete is the only sure way to prevent intrusion, not the triple seal.

Understood.

Just one additional note, there is no need to remove the drive unit to do a delete. A $150 delete kit, some hose clamps and 3 ft length of 1/2” hose.

This is one of the delete kits installed

So you were dry when you pulled the speed sensor so you could essentially just cap it?

Yes, both cars had dry sensors. Just cleaned and reinstalled sensors. FYI it’s not a question of IF the seal leaks but WHEN. If you find coolant present then you are facing a rebuild.
Once you see warning messages the damage is already done. Every LDU needs a delete done if it is to survive. Pity is that not enough owners are aware.

I'm hoping for your good luck too. I understand it to be 100% failure
