EGR = exhaust gas regulator :undecided:, maybe, just a guess

like gaz said, and it can block with sooty deposits thus causing a fault signal, if you read one of the "how to"guides at the top of this section -TDI- it describes how to clean it. not tried it myself, but sounds like what you're experiencing.

hope it helps  :smiley:
