I wouldn't use that as a door-stop!!!http://www.ebay.co.uk/itm/260968140...NX:IT&_trksid=p3984.m1497.l2649#ht_2998wt_924
with a year guarentee you cant go wrong and can always get a refund if it didnt work. they say they use the same stuff as bosch may be the same you never know so many different sellers out there to compare i just rely on feedback. just a suggestion and review of it. I have no way of checking the calibration so I wouldnt know the difference.
thats fair enough every person has their own opinion. if it fails I can get a refund and buy genuine but no harm in trying to save money. I know the expression you get what you pay for but ive got the origional in my boot incase any change does occur simple 2minute job to change back. OBD hasnt picked up any fault though
