During winter my 320 CLK 2001 W208 was parked up and the battery went flat. Since charging my battery the soft top has not worked properly, it was working perfectly before the battery issue. I have taken it to 3 different Merc Independents and none have diagnosed the problem as no error codes are coming up so I was informed! Although the roof comes up and down but the control unit seems to get confused was what I was told. The rear headrests which double up as roll bars won't go up or down probably related to the problem for sure. Today I took the car out for a drive and tried the roof, to my surprise it came down as it did not previously but won't close now!! Any help appreciated as the whole situation is very frustrating!!!
