BMW dealer codes

[Jdsheff]

Hi everyone - not sure who has come across this but tried asking BMW for the following dealer codes so I can match up service history key print out (very limited) for my 2006 Z4. If anyone knows or could point me in the direction I need it would be greatly appreciated

I have the following:

BMW Service on 7 July 2006 (mileage 5705) dealer code code 06074/01
BMW Service on 10th August 2006 - no dealer code
BMW Service on 22nd March 2007 - dealer code 06074/01 (mileage 8721)
BMW Service on 28th March 2008 - dealer code 08653/01 (mileage 14,778)
BMW service on 26th August 2010 - dealer code is 10048/01 - mileage 30557
