hello just bought myself a 900 turbo on a m reg plate its done 130,000 miles and its got a sensonic system on it the car wont start and there is a light on the dash board " CHECK ACS" what does this mean and are there any easy ways so solving the problem cheaply. i have checked the fuses and going to disconnect and reconnect the battery to see if i reset the unit. its was also difficult to get the car out of reverse this morning.
