As the car has the perfect service history I thought it makes sense to get the Haldex done at 4 years even though it hasn’t been 20,000 miles yet. Only thing bothering me so far is the knocking noise when coming on and off throttle at low speed and depressing clutch at low speed. Think it’s the engine mount issue, it’s what it feels and sounds like but the noise is the only symptom that I can tell so far. Shall I just get the aftermarket low engine mount fitted my a specialist?

My car does that same knocking noise, and was my only concern when I bought it (well the whiny drivetrain was too, but it seems that's normal)
But the knocking noise is also considered a bit normal on a manual... they are just clunking clanky.
Interestingly when I looked underneath to see if the lower mount was buggered and causing excessive movement, I noticed it was actually an upgraded one so solid as a rock.
My gearbox mount was a bit clunky and wobbly so I replaced that. I figured maybe that had worn more because the lower mount didn't move now.
It's marginally better with the new gearbox mount, but really I think upgraded mounts are a bad idea unless you do them all.
The reason being that if the lower mount is made solid, the engine just pivots about the next weakest link. Since the standard mounts are probably designed to allow the engine to naturally rotate around the gearbox mount (closest axis to crank), the engine top mount and lower mount do the rocking motion.
If the lower mount is made rigid, then the engine will pivot about that point more. If that happens the gearbox mount goes from a rotational movement to a translational movement.
Since all your gearbox linkages are right next to it, then the linkages are moving forwards/backwards during changes, and on/off throttle is allowing the engine to move differently to the designed movement.
There is also the thought that when whichever previous owner fitted my sporty bottom mount, they didn't use new stretch bolts on the sub-frame.
That could also be clunking around a bit when the engine moves around.
Personally I find the lower mount and associated presence ruins the R32. I think it's making my gearbox clunky, the shift and drivetrain lash worse, possibly making the subframe move a bit due to re-used bolts and the higher forces it sends into the subframe... and finally, the clutch pedal vibration and transmission of NVH isn't so pleasant due to that lower mount too (I think that's why my whining drivetrain seems more obvious too)
So yeah. Either do all the mounts upgraded so the engine still reacts as intended under torque. Or replace with OEM if needed.
And if you do replace them all, the car will probably feel horrible vs how it feels now.
I've yet to replace my lower mount back to OE. I've bought it, but I didn't realise I needed £30 worth of stretch bolts to do it right. I'm betting when it's done my car will be a much nicer place to be and make less weird noises.
And anyone who says you need to use a fancy lower mount to get a 'sharper' response feel from the engine, then the only way to do that really is to change the standard engine mapping which is set up like slop to begin with.
