Decoding the VIN

 

Hello, Newbie alert! I’ve just joined after purchasing a 1989 S4. It’s a very low miles car from Brunei and as such its history is somewhat shrouded. 

I decoded the VIN using the brilliant tool on here and it said the car is a 928 S4/CS. 

Car is an auto with a sunroof, so at 1st glance seems unlikely, but the sultan ordered some pretty crazy stuff, so a CS with a few luxuries is certainly not impossible. Or am I misunderstanding the info in the screenshot?

just wondered if anyone had heard of such a beast?

Thanks in advance.
