Purge Switch-Over Valve on a C220
Is purge switch-over valve also called vacuum change over valve? Ref: Mercedes p/n 001-540-86-97. Where is this part located on the 1996 C220 model and is it hard to replace? Also, the purge valve which is on the right side of the car in front of the w/s washer reservoir on the same car p/n A0004702293 is clicking. Does this mean that is bad and needs to be replaced? Any help is appreciated. Thanks.
