I purchased my 2nd s type a couple weeks ago, it is a 02 s type sport v8 with the CATS suspension.I noticed the ride quality was very bouncy and assumed the struts were bad. After doing some research I found the adcm module in the trunk and right off noticed neither one of the connecters were plugged in. I plugged both of them in thinking I would have a CATS light on dash but everything was fine. I took it for a drive and it drove like a new car, suspension felt great. I drove it probably 20 miles and no check light, I'm hoping it was that simple lol
