I've my TCH for only a month now and stumbled upon this forum, decided to read ALL threads from the first day onwards to make sure I get the "full" picture... Still working out the kinks w/ my User CP, so not sure how this msg will come out.

At any rate, I tried the link above and it's obviously dead by now. Can anyone guide me in the right direction? I've experienced the same issues Steve is talking about, and am *really* curious as to what I can do to bring my car back in EV mode w/o having to do a full stop. It happens even after I've driven for 40 minutes or so (at the end of my city commute, when getting close to home and 'cruising' down the neighborhood), so it's not about getting the engine warmed up again, for sure!

So what is S3a stage?
