ESP Leaks

[doggeorge1]

Have a 1999 CLK 320 with a leak on the esp/abs hydraulic block (003-431-24-120). The leak is on the back side toward the fender and coming from behind the plastic grommet. Is a kit available or do I have to replace the entire unit?

Hello and welcome, sorry to say that if you cannot find where its leaking a new pump will be required.

is it 59 in the picture

Actually it is neither of these pics, but very close. It is labeled ESP on top of the aluminum block with inlets for front and rear service from the master cylinder. Also has the four service outlets for each wheel/brake. I can see where it is leaking but I need to know if the part is servicable or repairable.
Tks for the reply
