replaced controled light module = self leveling suspension inactive

[rpedro04]

Long story...
Like many others i had problems with my side light and rear light's,so after new sockets...checking the units they still didn't work so i got at ebay the whole new LED kit,they look great but the rear light (now LED) look like they were trembling and the side light/rear light fault warning still came on but every thing work on exception to the rear,they work but are trembling.I had it checked and the right side was only getting 2 volts,so we decided to get a light control module,used but same identical part number,i did this because it seamed cheaper that taking it to the dealer and look at it and the used module we found was at a god price. Got it installed and the rear light/side light fault warnings are gone but the Self leveling suspension inactive warning came on but car fells the same and suspension acts the same,so i replace old to double check and the new problem goes away and old one comes back...Do i need to have the dealer reset the control light module or are both no good?
Thanks
