Faint smell of burning!!!

Hi lads, its my cousins Peugeot 207 it had a recent clutch change about 2 weeks ago.

But now there is a faint smell of burning coming up thru the car after its warmed up.

What do any of you's reckon, is this because of the new clutch, or maybe the mechanic

who changed it spilled some fluids, but after two weeks i would have thought any smell oil or

brake fluid would have gone.

is it a burning or slipping clutch smell or burning oil smell they smell very different . ring the garage where you got it changed and tell them the problem least they should do is get it back just to check it over.

I guessing myself its oil or brake fluid, clutch shouldnt be slipping

already surely, best bet is to bring it back, since the smell only came on since

they were at it.
