Hi. I have to replace my expansion tank (and any other recommended parts) on my 2019 540i. Just looking for a recommended source for OEM parts and maybe a good DIY video.

Thanks.

Others will correct me on this if I am wrong. I replaced the expansion tank and went with the least expensive supplier. Normally, I would suggest FCPEURO for most if not all parts as they are knowledgeable and offer complete kits for moat projects. This is helpful in the sense that you are not having to research and purchase all recommended parts to be renewed. But the expansion tank you could get from rockauto for a good price. You could include renewing the clips but I am not sure that us necessary. I do it just to be safe. Otherwise, those who know better than I do may suggest renewing all hoses and connectors while you are at it. That's a bigger job but it has to be done at some point depending on the age.
