Hello folks,

I am reaching out for your aid in determining whether to do this job at home - I have undertaken more advance projects than a ETA replacement before - or to send it to my favorite local Volvo specialist.

I have an 05 V70R 6-Speed with about 113,000 miles on it. I had it in to the specialist recently due to an inconsistent idle and they pegged it as a malfunctioning "ThrottleBody". i am aware that while they diagnosed it that they had taken it off and tried to Clean it, but the "Reduced Engine Performance" light came back on only after a couple of days. So I think it is time for a new ETA or ThrottleBody unit.

What I want to know is if I choose to purchase one myself - I've seen a few good options on Ebay - am I required to take it to the Dealership or Qualified Specialist to have it REPROGRAMED after? Or do the post 01 Bosch ETA models vary from the earlier ETM models that required reprograming? i would of course love to avoid taking it to the Stealiership, but don't want to make the problem worst. Any advice is appreciated.
