What performance mods are on the car ?
And when you say overboost what psi are we talking about ?

id have thought the leon had a vnt type, and overboost is due to a sticking vnt from carbon build up, from pottering around...not working the turbo hard enough!! serious though, use forte diesel additive, in a full tank of diesel, and work the engine hard... it will clean itself up
I think he has a 1.8t, judgin by the posts he's started on the forum.
And there's a lot of things which can cause it.

The software controls boost using the N75 valve etc etc, so if the N75 is stciking, you will get an overboost. N75 faults normally cause surging issues though as the ecu tries to correct for them.
Is it something it has suddenly started, or has it always done it? What spec is the car?

That experience is correct too!
My mate MOT's taxi's and when he does the smoke test, clouds of thick black smoke come out and eventually clear up.
Not an issue with the 1.8t though.

What garrett turbo is it, and is the map suited specifically for it?
Not the cause of your overboost, but you may want to go for range 7 or even 8 plugs, 6 are stock, and might get a bit hot with your setup.
