ASC fail, restricted performance
#1
![Default](/forum/images/icons/icon1.gif)
My '99 XK8 convertible will go into restricted performance and flash ASC upon reaching highway speeds (60-70 mph). It resumes normal performance when I switch off ASC and seems to perform responsively. The only other issue I have is, if she sits for about three days, the battery needs recharged. This started before the TB rebuild. She's got about 66,000 miles and just had TB rebuild (outstanding job by ASI). Any ideas?
