My CPS is starting to go too..
Well, I guess I need a new CPS also. I am having the same symptoms as several others. The turn over but doesn't start when it is hot but after about 10-15 minutes we're good to go. I checked a bunch of websites I found on the board of where to get the part (germanstar.net ,Benz bin ,alloemautoparts.com,autopartsauthority.com) and the price must have changed since the posts. Others said they were paying $50 and $60 for the part and I cann't find it for less than $120. I broke down and called my dealer and they have it for $114 (in stock - guess why, they probably replace them every day). I then had me transfer me to the service dept (from the part dept) and I told them that I plan on bringing my car in for inspection next week (which is true) and how much to change me for the CPS install. They told me it is easy to install and he would charge me $45 to install when I bring it in for the inspections. Do you think this is a fair price??
$114 for the part and $45 for the isntall = $159 total?
PS..there is no way my car should not pass inspection so I don't think they will be able to get me on that end. Just an fyi..
