6 months ago i had a GTT conversion on my Clio, at the time, the speedo didnt work
Andy at GDI said simply replace the cable and it will work fine, so i did that, 5 months later ..................................it didnt work
I then tried another set of clocks 2 weeks ago, didnt work
Today ive tried the 3rd set of clocks, still didnt work
i was gettin worried that, though highly unlikely, it might be the gearbox, until..........
i then realised i had the connector upside down going into the back of the clocks !
well at least it works now !!!
