Question: does the heating element attached to the filter also need to be changed at same time as the filter? What is recommended service interval for the filter heater? If not what indications are there that the heater needs replacing prior to or upon failure?
The $32 mahle filter is a great price but can only find the bmw filter plus heater part which is $275ish BIG difference in service cost. Much appreciated!

I've not heard of changing the heating element on a frequent service interval. BMW branded filters can be purchased without the heating element as well.
I'd recommend short intervals for the fuel filter i.e. Annually or <20Kmiles. Factory interval is 40K which is too long IMHO. See my images above with the amount of sediment entering the filter.
