We just did that trip. Stop for lunch at the Promenade or Rocklin to fully fast charge. The promenade EA chargers are hit or miss if they are working tho. Then drive conservative up the hills and mountains to Truckee, where they have a new bank of EA chargers. We had about 70 miles range left when we arrived there, after some nice downhill regen from the summit. You would probably be ok getting to the north side of the lake without charging at Truckee. Good luck!
Last December I did the trip from the Bay Area to L.A. down I5. It was my first trip in the e-tron and I found it to be pretty easy. I stopped to recharge more often than I probably needed, only because I didn't want to risk it. Went at above posted speed for most of it.
Wut?
Some chargers fail to initialize. You have to grab the handle and lift up (and in) a little until the initialization process finishes. Once the charging starts you can let go. I had this problem at a Recargo Network charger and the error message even suggested the fix because "older cables are heavier". The first time I tried it didn't work. You have to firmly lift and push in for it to work. I have heard some EA chargers have the problem too. Someone told me it is a problem with Huber + Suhner cables, but I wouldn't know how to check that.
Very very good to know, thank you! I have only had to DCFC three times so far (COVID has cancelled many longer trips that were planned) but I had issues the first time.
