W140 Service Manual
But I am happy to report that at, www.alldata.com has full repair/service/spec's online for the W140 {S320, 420, 500 +} S Class as well as many other cars. On the site go to "DIY For Owner's" click on purchase and enter your Mercedes and model to see if it is covered.. The cost is $24.95 per the first year and $14.95 each year after. The online version is very updated and current unlike a CD that cannot be updated.
I have subscribed and I am very happy. It offers full detailed repair for almost everything. Door regulator's, head gasket, A/C, all service bulletin's that the dealer gets. Part numbers and drawings of repairs, troubleshooting, problems. A wealth of information and how-to's. I haven't been able to view it all in three evenings of looking. I will know the car inside and out by the time I am finished. You may have to click on several link's before you find what you are looking for, but it is there. Pages can be sized for printing though, not pdf.
This is the same information that many independent shops subscribe to and use to repair your S Class W140 Mercedes and when the mechanic doesn't know what to do or how to do it.
