just spoke with dealer and they need to book it in and check if its faulty - if it is, then they will provide a new one - if it isnt, then you have to pay for labour -
 
the 12 month warranty was with euro car parts.....i bought it as a cash sale through my mates garage on an exchange basis for £60 all in. I think theres a £30 surcharge if you dont hand over your old one?
