Does any one know of a good source for a rebuilt or used Control unit. My dealer wants close to $1200.00 For the part and another $200.00 for labor. I have a ADS warning light. They said thier computer will not communicate with the control unit and they are not sure replacing the control unit will get rid of the warning light. I've put over $6000.00 in repairs a month ago (mostly in parts). Seems like any small thing turs into $2000.00 or more.There has to be a better more cost effective way to keep it running. It has 79,000 miles on it and I am the original owner. I've always taken good car of this car all work by my dealer. It seems like it starting to fall apart now. And I doin't whant to get rid of it. Any help out there would be most appreciated.
