According to ETKA, it is indeed a relay, where you stated. The part number depends on engine code, which are as follows for the 4.2tdi:
CCFA - Part# 038907281B or 04L907282B - stamped 457
CCFC - Part# 4L1907282 or 4L1907282A - stamped 652
I would double check which you have before proceeding (as ETKA can sometimes be wrong).
