This pump is a 10 warranty with MB. You should go to MB to have them make the repairs.

thanks for your replay but what does it look like is it the SBC Unit or another unit because i have changed the SBC for almost 1 month from know so please if you have picture of it can you please send it to me

If you have changed the SBC unit and it doesn't work this is what I would suspect.

1) Air in the system
2) Incorrect brake fluid must be DOT4+ for the SBC system meeting MB specs.
3) Defective unit

Photo of MY SBC unit attached.

Go to the dealer for service on this warranty. When you state "you" does this mean you actually did the work or hired it done by independant? Or did MB do the work?

Thanks alot

yes i have changed this unit and it cost me almost 1500 euro and i did it independent because her in my country we don`t have the MB showroom and i had tried to contact some of our nears country but they said that they cann`t help me in it

Sounds like they won't. If you arrived at a authorized dealer it might be difficult for them to refuse given you have a major safety issue and warranty item.

I would suggest you check my previous post for items to inspect.
