V-class windscreen defrosting unit

[jjkenya]

Hi everyone

The washer bottle on my V class (2017 250 BlueTec) is leaking. The leak is coming from a broken clip on what looks the defrosting unit - photo with the white plastic in it. I think the broken clip is on what is a defrosting unit, because it is upstream of the pump and it has a pair of wires running into the hose pipe. Unfortunately I can't find the replacement part online - neither the part number of the whole assembly (i.e. defrosting unit + hose line assembly) nor the individual part itself (defrosting unit only).

Any ideas where I might get a parts diagram, or indeed source the spare part?

Thanks in advance

Just an update - I think the required part number is the whole hose assembly.
For a V Class, this appears to be A4478607100.
