MHEV or no MHEV (1.5 TFSI)

[SpanielD]

Long time Audi owner here with a new A3 on route for the better half (although long lead time, early-June estimated).

We've gone for the 1.5 TFSI S Line S-Tronic but even the dealer doesn't seem to know whether or not a June delivery car is going to have the MHEV system. I've read stories of Q3 orders going in and being delivered with the 48v system in place, without the owners knowing beforehand or showing on the order form. 

It's not a game-changer either way but looking to see if anyone knows if we're likely to get it or not?

Cheers
