The dates line up (engine assembly, VIN); the broach marks look good. The only issue which jumps out at me when viewing your photos is that there are 'gouges' or ??.. over the DZ application code, those could be due to some careless person scraping the pad?? A very close examination of that area would be in order.
Otherwise I don't see any issues with the stamps, nor do I see any problems with the TT, (but I'm not a 'repro TT expert'... it looks real to me.
PS. Your car probably completed assembly on 3 or 4 February (about 2 weeks after the engine assembly date) which is very consistent with other cars.
