Hi Guys,

How do I find the engine O M number for my car it is a 63 plate C class W204 M274 engine. Do I need it how many ID`s do engines have and what does it differentiate.

Please advise many thanks.

Jeffers.
 
Im sure someone will correct me but I thought the engines were just M if petrol (ie M111, M271 and M274)
And the diesels were OM (oil motor) (ie OM606 , OM651 and so on)
 
As above.

M = „Motor “ (engine)

OM = „Öl-Motor“ (oil engine)
 
If your 2013 car is a C180 CGI, then it will have the M274 Turbo 4-Cyl 1.6L petrol engine.

If your 2013 car is a C220 CDI or C250 CDI, it will have the OM651 Turbo 4-Cyl 2.1L Diesel engine.
 
Cheers guys appreciated.
