Question about Mercedes-Benz 420-Series
Hello, I've never seen a 420sel with hydro-pneumatic suspension. Are you sure that it isn't a 560sel?
Anyway, there is a tank on the left side of the engine compartment close to the front that is a little larger than a qt jar. It may look yellowish in color and has a steel line going to it with a screw on lid and a dipstick. Pull out the dipstick and ck the fluid level. If it shows nothing, fill to the correct level only using the Correct Mineral Oil That It Calls For. If it is full, you probably have a bad pump that is located on the front of the engine.
I hope this helps.
