So I have an X-reg 2000 S3 APY parked alongside my T-reg 1999 APY, and there's some difference to note.
My early one seems to be poverty spec, then optioned up to what it has now, but on the later APY there are a few subtle updates you wouldn't notice.
*Early APY has no ESP(maybe an optional extra?)>Late APY has ESP as standard.
*Analogue clock in dash pod>Digital clock with date and time.
*DIS shows when doors are open graphics on late APY.
*The doors have red lights on the B-pillar edge on late APY, early one doesn't have this.
*OBDII socket is under the ashtray>The OBDII socket has been moved to the under dash position like the facelift models on the late APY.
Early APY can't switch Airbag off>Late APY has the Airbag switch in the glovebox.
These are thing I have noticed just poking around for 5 minutes, everything else seems pretty much the same. I have no idea when these update took place?
