My 220 cdi sometimes smells of oil - 2006 Mercedes-Benz C-Class

more likely gas is leaking from the gas tank not oil. maybe you blew a rear shock instead?

Can be any thing -- next time happens need to figure out if problem is spark or fuel --- possibles that don't throw code fuel pump. Fuel filter air filter. Egr valve crankshaft positioning sensor Ignition switch Coil Etc these are just some of reasons have scanned for possible pending codes

Could be the instrument cluster

check oil level in gear box

Fuel oil--- is a #2 oil & sometimes has kerosene in it also & is not like gasoline, that is combustible

Fairly safe,just smells strong

how to change starter motor merc 220 cdi avntgarde step by step

For 2002 Mercedes-Benz C 220 CDI WDB203, engine code 611.962, the engine oil capacity is 6,5 liters, with oil filter replacement.

okay the dealer may be right,the wiring sometimes breaks from opening and closing trunk,the trunk release operates on the same power as door locks, if door locks work its not a fuse,check the wiring harness in the trunk near hinge, this system is a complex one,so if you dont see a broken wire in the harness,(you will have to untape the wiring to see every wire) have a tech check the system.

When parking your vehicle, try to put piece of white paper on cardboard paper to se if there is any leak.
Sometimes oil can drip on your exhaust and trigger the smell thru your A/C Heat duct.

not sure on this one see if this website will have your car listed www.autozone.com
