On approach into SBN around 10 NM from the airport we were given a heading to join the 9R LOC for the ILS while level at 2;600 feet in IMC. As the LOC was coming alive we received a GPWS warning. The Captain executed the GPWS escape maneuver and the warning went away. We notified ATC and leveled off around 3;000 feet. ATC vectored us back around and we shot the 9R ILS without any further warnings (this time ATC kept us at 3;000 feet until intercepting the GS).We complied with the GPWS warning and notified ATC of our change in altitude. Suspected false GPWS warning as there aren't in high obstacles in the area.
On approach into South Bend we received a GPWS Terrain warning we were being vectored for the localizer at 2;600 feet we complied with the warning and climbed to about 3;000 feet the warning disappeared and we were re-factored back for the approach with no other incident. ATC verified that he did not see us go below 2;600 feet.We were IMC at the time and could not verify the warning was false.
An air carrier crew being vectored for the SBN Runway 9R ILS received an EGPWS terrain warning at 2;600 feet and because they were IMC executed the escape maneuver even though they believed there was no threat west of the airport.
