Hi there Loz,
My van is a 2014 SE 180 4 motion.
I classed it as a 5.1 as the only matching image of the Haldex unit I found was on a post for a Transporter.
While I was doing an oil and filter change it occurred to me that I did not know where the fuse was for the pump.
I can find the fuse for the control unit but would expect a seperate fuse for the pump.
I guess as an ex Merchant Navy Chief Engineer I am used to control and power circuits being segregated.
It does not seem a great idea to have a 15 amp fuse with the pump pulling 2.7 amps when operating normally.
Pump fault then would potentially toast both pump and controller without fuse blowing.
Thanks anyway for your helpful comments, it is always useful to get info from other fellow owners.
Regards
Dennis
