So after fitting these a couple of weekends ago and thinking I made a mistake to then revising the mounting points by using rubber matting as between the mount and the chassis there was a noticeable improvement. I then drove down to Glastonbury and back and it still felt quite harsh but the journey back did seem a lot smoother and more like a lovely E60, 6 cylinder diesel engine with a lot less nvh. I put it down to being tired on a late night drive and not noticing the vibration and harshness as much.
But today I noticed there is considerable improvement, no idea why, maybe they've been broken in but it does feel and sound so much better and with that feeling of solidity as it the engine and gearbox are in sync with the chassis with high speed cornering and in town speed humps. I no longer feel as if I made a mistake fitting them and am very pleased with them now. I don't know the make of these, they look like a homebrew job but I'm happy with them so far, bought on eBay and the seller was VAG Remaps. I've attached images below from the seller for those that are interested.

Those are genuine VW OE mounts. They have the VW Audi Group number on them.
They are previously used and probably were not in good shape when someone did this to them; someone shot red polyurethane into the voids, painted the cast alloy, and resold them. I would seek another set as most of the NVH may be due to the condition they are in and no amount of added poly or padding between them and the body will fix.

I think the 034 Motorsport solid rubber ones would probably last longer. Liquid poly poured into voids has a history of not lasting because it's not vulcanised as a complete unit, but rather 2 different materials and shure ratings occupying the same space. The two will detach at some point, but if he's happy with them, that's all that matters.

I hear ya.
I was mostly responding to their statement " I don't know the make of these..." and then explained what they are. Purely to inform them.
I agree with your assessment of the two differing materials.

Ah OK, I must have missed the part where he bought them like that. I assumed he'd filled the voids in himself!
This reminds me of an HP Academy video I saw recently, where they mentioned an issue with DBW throttle bodies (the typical Bosch/VDO/Continental ones we're familiar with) and engine vibration. Excessive engine vibration can cause problems with the throttle position sensor tracking properly, causing intermittent limp modes and other problems.
Race teams now isolate the DBW throttle between 2 Wiggins connectors, or a couple of silicon joiners. Just made me think about the time I ran stiff engine mounts and had some running problems :thinking:
