No, but no leakage seen around cap. Usually one would see a white dust like residue if a leak was present. For a long time I had a bitch of a time sealing the 1/2" top hose to the barb on the expansion tank. I finally got this to seal. I just checked this again and no residue there so I'm confident that this is not an issue.
Ever wonder why 5 series electrical issues are common and complicated.. Spend time here and you will understand why.
