I racently had to have my Freel2 o8 HSE ecu recoded to include a towbar which I had fitted, since then the the only way to unlock the tailgate is via the key unit pressing the tailgate unlock button, it will not unlock by pressing the general unlock symbol on the key unit nor the one on the dash, all the other doors unlock as normal. Any Ideas please or will I have to take it back to the recoding guy?
