help engine problem not sure?

went london and back no problem the other day but today jus notice this burning smell smells like fried brakes but my brakes discs everything are ok liquids are al ok topped up

anyone know what could be the problem or shall i just ignore it because its not affecting the performance.

You got discs all round ??

na jus the front buh the smells cumin mre from the engine

The only other thing I can think is clutch, as that would smell like brakes and is obviously in the engine bay

inner arch plastic's a maybe, have you lowered your car, changed wheels recently?

powelly yes jus recently changed ma alloys put the vti fan blades on ma ej9 so wud it b rubbing or sumfink buh derz no rub marks or anythink

If it's rubbing the plaggy inner arch the tyre will not be marked. You'll have to jack it up an look at the liner. If it's worn nice an smooth then you have your answer If it is get a sharp knife an just trim away the bit thats rubbing, you don't need to remove the whole thing.
