Need some help if possible , just repaired my oil cooler seals . The car ticks over fine but I have a fault code P0193 and it seems to be in limp mode when I drive it . I am going to pull all the plugs and refit them any thing else I should look for . The vehicle was running fine before I took it apart .Any advise would be greatly appreciated .

 

It would be very helpful if you would let us know year and model you are referring to.

 

its a 320 cdi 2007

 

What is P0193. It's meaningless without a description.

 

 

the code meant high rail pressure also I have no turbo boost , but I does go through the gears

 

Your code reader is useless because it transposes M/B codes into P codes making it difficult for forum members to help you. You must have a scanner type that will read all M/B codes.


Below is the correct code # for your problem. Read the highlighted section and decide what your next step will be.

 

Thanks, but generic OBD code descriptions are not helpful when diagnosing a Mercedes.
