There is only one IAP, a VOR/DME circling one, with a 1500ft MDH.
Actually not a VOR/DME circle to land, but a VOR/DME which takes you to a MAPt, at which point you have to cancel IFR and join a VFR circuit if you have the field in sight, or perform a missed approach under IFR to the SSE.
No part of this mixed IFR/VFR procedure, nor the missed approach, takes you west of Voslau. The position that vanHorck listed is 1 nm west of Tango, one of the VFR arrival points, and is about 5 nm west of the airport. Terrain there is 1076 FT MSL, with Tango specifying a minimum of 2500 FT MSL. The VFR circuit is NNE of the field.
If you have access to the Eurocontrol site, here are the procedures and VFR charts:
