That does seem pretty long. Tesla service here takes "off road" vehicles very seriously, and they pretty much pull out all the stops to get them running again.
I agree two weeks is a long time but I am 350 miles away from Atlanta, the newest service center. Apparently there are two of them and one is California for a week for training. So a trip up and fixing it is about two days for them. While frustrating I try to put myself in their shoes as they are a new company trying to grow. At least they have gotten back to me in a timely manner.
Well I have to hand it to the Rangers. They were superb in finding the root cause of the problem we hope. Apparently some pins, or rather plugs on the large connector to the PEM were not holding the pins securely, creating a partial connection. With slightly more resistance the two accelerator circuits would not agree and thus the fault was thrown. The increased the tension and the car is running well. I got to help remove the PEM and since it was out they did a thorough cleaning. It did not need it as my PEM was quite clean; but now I feel confident in doing it myself. Or I should say with a helper as with the PEM in a 1.5 weighing about 140 lbs and it is a bit much for one person. They also confirmed that tests are underway for a new motor/PEM upgrade that would significantly improve performance. That would be cool if it comes to pass.
I am quite sure they did not use a service computer to "turn the car on". But I am 99% sure he turned off the power through the VDS and then reenabled it. That part I forgot to keep a close tab on as I was in the back helping remove the PEM.
I feel confident I can get the PEM out and cleaned but will need some help or poking around to find out how to deactivate the system. The prior ranger just lifted the PEM slightly and blew it out. And that range pulled the safety disconnect first. That way the radio looses it's brains. After seeing the full removeal that is the better way to go for a cleaning in IMHO.
Here is a shot of the motor.
Dave thanks for the pics. The 2.5 PEM is quite different. I'm hoping it's the same as far as not needing their computer to re-enable it. Which mounting bolts did you have to remove?
The bolts are a bit of a challenge. There are two from the underside you need a 2' extension and to remove the bottom pan that covers the rear of the car to reach. Then there are two, one on each side, that connects to the battery and on the drivers side there is a grounding strap to the battery pack just infront of the attachement bolt. Then there are 8 connections I do believe to the PEM, 6 of them are from the underside and not particularly easy to reach, but not impossible either.
Has anybody seen this warning on the VDS?
DMC: Wear Factor Warning
It's a debug-only warning so you won't get this unless your car is in debug mode (which I requested).
What is the DMC?
OK here's the official response from Tesla:
What it means, is that the car thinks the tires are a little bit smaller than they should be (smaller size, or too far worn down). How is the wear on the tires? Did you recently swap to winter tires? You can attempt to get rid of this fault by relearning the tires.
