It may be gearbox software related, battery, I had a similar issue when in Sth Aust, took it to a dealer in Port Linclon and he upgraded the gearbox software and all was good.
I'd have the re-map removed to count that out first.

Everything has been going well but haven't been on a freeway, I am hoping it was just dirty/ rich fuel
Complete disaster this weekend the car completely did the same thing ...nightmare ...almost killed
Thank god for Ritter's
Turned out to be a cracked turbo hose, all sorted now, been on the freeway all day testing no issues,,,, great.
Thank you
Yes Justin I have asked if there is anything else lurking and the guy recommended replacing the injectors
