Hi people, the search function for “AGR V50 2.0D” is already haunting almost hundreds of entries. What I did not find, however, is an answer to the question whether you can change the AGR valve yourself? Sure, you will answer, everything is possible. But according to the Haynes V50 manual, it is necessary to release the engine and let it down a bit. But for that I lack the means. Now the question arises, is it possible with hardship and distress also without this procedure? Does someone already have the AGR I have a second AGR at home (cleaned, tested), which the friendly one changed to me about a year ago. Now the V50 is jerking and twitching again in cold weather and I tap again on the AGR valve, as the same problem as a year ago. Many greetings, Crookstone
