    Default Eberspacher D4 fan noisy

    The fan on our Eberspacher D4 is getting noisier. I suspect the bearing. Has anyone tried fixing this part?
    On eBay are genuine fan assemblies for around £230. There are also unbranded fan units for £95. Has anyone any experience with these unbranded fan units?

    Have a look at this:

    Seems you may be able to overhaul and replace the bearings.

    Have you cleaned the fan blades? Even a small buildup of clag can make the fan noisy and inefficient. Suggest that's the first step.

    Quick follow up. Bought aftermarket part off eBay. Just fitted it. All’s well. Very much quieter. Fan unit is very quiet.

    Can you please share the link to the item on eBay? I may just buy one myself for my D4 fan
