Hi guys n' gal's

I'm looking to buy a Mk4 in Jan and I will want to connect up my Vag com to test it for errors etc before purchasing.
I was looking at http://www.ross-tech.com/vag-com/cars/dlc.html for the diag port location.

I was just wondering is there a standard location for it in the Mk4's? In my Mk3 and all other Mk3's I've seen, its beside the ashtray and accessed be removing ashtray etc.

Is there such a thing as a standard location are are there 1 or 2 common locations etc?

Any help appreciated!

Ps Have a happy crimbo and a Mega new year!
