Just checked and the electric vacuum pump in the braking system only applies to the petrol engines (BBJ, ASN, BVJ and BSM).
Now this or may not be relevant, but might be worth checking for a perished pipe. The 3.0tdi also has a vacuum system on the EGR, but no idea how it operates. The attached image might help.
