Hi all sorry for late reply. Thank you all for advice really appreciate it . I read the mot manual back to front on the emission lol my hood is registered 03 August 1998 but mot manual states before 01 august 1998 so had to find proof it was manufactured earlier. Thankfully i could thanks to an old v5 . If i hadn't found this i would have to get a copy of iva/sva which is an online application not sure how easy it would have been... on the dvsa mot system its only dated 03 auugust 1998 and no emission levels on v5 so mot station needed proof before doing the test . Hope all you guys have had a good day
