i have a 225 tt and just recently the fuse that regulates the horn (no40) keeps blowing as soon as i depress it.has anyone any idea why?

Know nowt about the TT. However I would disconnect the horn/s (usually just behind the grill/radiator) attach a 12v bulb to the wires/ground and then re-try the horn button. If that does not blow the fuse then it is most likely a faulty horn.

BTW there may well be two horns.

If it still blows the fuse with the bulb then there is a short in the wiring, unlikely though.
