The strut top mount is nowhere near the top of the strut body?
u mad bro?
Do you know what a strut top mounting is?
Not the top mount, the top of the actual damper itself, where the damper rod goes in.
ie where the arrow "Piston Rod Movement" is pointing to on this diagram

Quite familiar. I'm interested by what measure are they nowhere near the top of the strut body? Top mount bolts directly to the top of the strut. I would consider the strut to encompass everything up to the top spring cup. Even if you were being peculiar and talking about the top of the damper body, that is what, 6 inches away. The only thing closer than that is the turret itself
Point out the BS for me, please.
The OP would be best just asking the guy who diagnosed it in the first place, ave a look at it, judge for themselves. There's no smoke without fire though...
Can't say I've ever seen a strut with play in a sliding bush, done them a couple of times on MTB forks but never a car. In saying that, had a couple of dampers leaking oil, didn't investigate just replaced. In both cases though, after oil came out the damper was blown and totally ineffective.

Stay confused by all means. OP, it'll be fine...if you hear any knocking from the arb bushes then by all means get it sorted...still sounds like the tester is being picky with the strut top mounts though...

Here is something that may shock you...garages will put advisories down if they think they will make a quick buck out of it. Classic example being 2 days before my last MoT I replaced discs and pads all round, car had done around 8 miles between this and being taken for its mot amazingly the only advisories bar my sat nav cradle, were that the pads were badly worn but not to excess and that there was pitting and corrosion on all 4 discs, corrosion i could possibly believe but these were brand new discs and pads. The even gave me a quote for the discs and pads with the certificate
Oh for **** sake..
When the strut is tested, it is in the drooped position and the wheel off the floor, so when they rock the wheel and feel the play in the "sliding gland or bush" < that is the bush/seal at the top of the strut body where it meets the chrome shaft/Piston.
It is quite common to have a little play in this bush at full extension as the chrome shaft is not in contact with much of the second (usually PTFE) "bush" within the shock body. so play is evident.
The MOT tester records this as an advisory as said, to cover his ass.
When there is play in the thing at normal ride height, that will be the time to worry.
This will be accompanied by a fair amount of knocking over rough ground so easily identifiable.

The item I am talking about has nothing whatsoever to do with the top mount, why do you insist on going back to this?
I'm presuming you have absolutely no idea what a 'gland' is (besides the things in you neck and armpits that feel painful when ill)? It's a seal, that allows linear or rotational movement between two parts whilst preventing the flow of liquid, e.g. oil. Exactly where in the top mount do you think a gland would be used?
If it was knackered, i would expected an advisory or fail for a leaking damper...wouldn't you...
Could be what Fuzz said, seems a silly thing to advise on if it's actually just normal operation, perhaps the tester is inexperienced.
@SilverTongue, can't say I've ever experienced anything like that. Sounds to me like they need reporting to VOSA because that is outrageous.
