Can anyone please please help, i have a c200 kompressor on a 51 plate. I have just started getting problems when i lock the car with the key fob, the car will lock but all indicator lights keep flashing and if i press key fob to lock again they all go out but after 2 mins alarm will sound. i have replaced the fob batteries and diconncted the battery and reconnected but still nothing.( central locking did work for 3 hours after battery was disconnected but came up with a fault saying esp unavalible after 3 hours eps workning locking not ???????????????????????????????????)
