I have a 2018 550 and the left Headlight assembly is making a ton of noise... the fan appears to likely have a bearing or something going out. A buddy of main hooked up a diagnostic and was able to switch the fan on/off and verify it is the fan and a much different noise than the right LED headlamp. The question I have, is this fan replaceable with out having to buy a whole HL assembly? I cannot find a parts diagram that shows the fan... so I am thinking no. But wanted to check here.
