Caro-Kann Panov endgame variation

Does white has a new approach to this variation?

More common these days is 6.Bg5 instead of 6.Nf3, specifically to avoid the endgame.  Beyond that, not away of a different way to play this.  If you are looking for a refutation of the Caro-Kann, it doesn't exist!

If there is no refutation with the Caro-Kann, basically this is a good weapon if you are fighting with strong players. It has a good drawing chances and if your opponent is not that strong in endgame you might outplayed him. But in this endgame variation is it a dead draw?

I will have to leave this to someone else.  I basically quit playing the Caro as Black about 4 years ago.  When I did, I only played 5...Nc6 I think twice and both times faced 6.Bg5, mostly played 5...e6, and as White, I play the Fantasy Variation, not the Panov (and against the Scandinavian with 2...Nf6, I play 3.d4, not 3.c4, so no Scandinavian Gambit with transposition to Panov).

I still remember all the basics, the traps in the 4...Nd7 lines of the Classical, etc, but cannot answer in-depth stuff from the endgame line.

Yes! I know this is almost 2 years late, but maybe perhaps you could consider 13. Qc5+, which actually has a better score for white. You are down a piece as white, but the activity of your pieces more than compensates! The computer calls it 0.00 but it's a dynamic way to play! 

Not necessarily. It's never a dead draw until all the pieces are off!
Having said that, the 70% draw rate in masters games after 13. Qxb5 (just going off lichess) suggests the position is fairly draw-ish. However, after 13. Qc5+, 47% of the 30 current games are won by white, with 33% drawn and 20% won by black. 

FWIW Aagaard recommends Bg5+ for white before the queen exchange and says it forces black to play f6 which is a slight weakening.  As for the endgame, if it gets to that position (I've had players trying odd things as black) then white is more active but has many weaknesses. Dynamically balance so the better player of that position has an advantage. (I dont think GM % wins means much of anything at my level and agree with Isaac that " It's never a dead draw until all the pieces are off!")

See this is what I also play as white and I also play queen pawn opening especially the queens gambit so I mainly play  it as queens pawn position against slav with semi open e and open c file where you could place your rooks and the major thing is you should not capture on c4 untill and unless your rook is not on c file 

Panov is a very good fighting and most attacking way of playing against the caro kann At least for me and it gives me queens pawn like position which I am very comfortable with 

I think you can take help of free short course of 17 variation by IM sam collins on panov attack that's how I am learning it and he also said its one of the best way to fight unambitious caro

This is the reason why I play the accelerated panov. When you delay d4, you make it impossible for black to play Bg4 without giving white a big lead:

Without having played this system for very long. I think white more often than not end up getting a space and development- advantage in this system, but yeah, whether or not you are facing the accelerated or the normal panov, black should probably go for the endgame variation. In the normal endgame variation, I personally favour black.
