What is this part?

Noticed a bit of oil (clear/amber) dripping off this part. I’ve cleaned it all up, I’m assuming it’s a spill from someone doing an oil change but it did get me wondering what this part actually is! This is the view from right hand side looking up just past suspension arm.

Evening

I'm not sure on the part... But I've only seen those connectors on fuel lines.

That does make my slightly concerned it’s leaking diesel then! Will see if the drips come back.

Thanks! That’s interesting- what is the likelihood it’s leaking there?

Diesel and coolant heat exchanger on D3
Diesel warmer I think
Yes diesel could be leaking from the connectors

The D4 has a bigger version for gearbox cooler

Cheers will keep an eye on it - are there o-rings to replace in there or would it be a new part needed?

Maybe new pipe. Need to know which pipe it is. Eg the one to the filter or

If it’s a D3, it is fuel

It's a diesel fuel cooler. Check the push on connectors are fully home. https://www.advancedfactors.co.uk/lr031827...3226-p.asp Faultmate MSV2 EXTREME
