Does anyone have any experience with having warranty work done on an E55 after RennTech modification? Do RennTech mods void the factory powertrain warranty? What if anything can you do to this engine without voiding the warranty?

Norb is correct. There is also one more thing to consider if MBUSA voids a portion of your warranty. Your car gets red-flagged. Once that happens, MBUSA has to approve any and all warranty work, even if it's not directly engine related, like suspension. So this equates into extra shop time. This is all too familiar for me.
Check the RENNtech web site for locations. MB of Sugarland is a dealer and there should be one in Houston.
