On a 'VERY LIMITED' amount of new GTI's (specific chassis numbers) the bolt that holds the gear on the oil pump has not been torqued, so in order to save any future slagging they are advising not to drive the affected ones and get them fixed 'even before' the Pre-delivery Inspections.
The fix involves removing the sump and replacing the bolt and torquing it.
Edited - The earliest UK Dealers could have known was mid-day on Chrismas eve so for it to be on any forum is very up to date, well done members
