I have a w212 220cdi 2015, this fault code is driving me insane. Its always there and does not disapear when i clear it.

the only light it gives is engine light but no abs/esp light. I have tried changing the radar behind front bumper but no luck.

cleaned all contacts and checked for faulty wires but still no luck.

i have some more codes on the esp

 

Please scan the whole car then we can read the faults descriptions in english.

We need to know what each individual modules is reporting.

You say "new radars without improvement".... be aware there is a long front bumper harness connector that ends up soaked on passenger side.

 

I will scan again and upload pictures.

the harness behind the bumber is fully dry and ive checked all conections for bad wiring, the fault is not in that harness.

the radar is for the colision prevention assist, wich is not working

 

The bumper radars report through the harness you've just tested.

Lets see what faults come up ?

 

 

based on these error screens, its pretty easy based on given context: either radar module is bad or harness connection is but you said is not bad.
