Strange thing under my car 1992 420 SEL
Any ideas ?
The manual doesnt say anything about it and I called the dealership to ask them what the hell its for and the guy was like You have what on a what? He had no idea either kept teling me to bring it in.
(Sidenote
ealership is 1 hr 30 min away)It doesnt do anything cept hiss when im idling and I dotn have any idea what this thing does and whether or not the hiss is good or bad.
Any thoughts would be appreciated.
Adrian
