I had the Mercedes dealership recently replace a broken pipe from my egr to turbo. I think that what is was at least. I have a 2010 freightliner 2500. When checking out the egr they said I had one stripped bolt and a very minor exhaust leak. The fix would be to replace with a new egr valve and cost $2000. In searching the forums I’ve seen many of you have replaced it yourself and it was fairly simple. I don’t have much mechanical experience and tools although I did watch a quick you tube video and it seems very straightforward. For this reason I think eventually I’ll have a non Mercedes dealership mechanic work on it. My question is I’m having bucking from a low idle into the first gear or so which seems to be an egr symptom. Other than that it runs fine. I’m about to drive on a long road trip from Florida to New Jersey. Is it ok to drive with this bucking? Most of my driving will be highway and it doesn’t seem to effect it once I’m at higher speeds. Any input is appreciated.
