e90 sludge issues

bk77 · 03-09-2012, 11:43 PM

Hi Guys,

Firstly thanks for all your input.

Car Specs: 2005 e90 320i Engine N45

I noted some sludge at the bottom of the engine panel, expecially on 2 hosts (See image).

I brought the car to two mechanics, one said it was the vac pump and would cost $1,2k to replace, while another said it was just a leakage of the host mentioned above.

Would appreciate if someone could identify:
1) The name of these hosts
2) whether the sludge is caused by leaking issues of these host or something else?

Cheers,
BK

bottom pic looks like it could be the power steering line, #3 in

No idea, sorry. I happened to know b/c I need the small rubber spring that's at the U joint of the line, and I can't buy it separately from the entire line, which is $$.

If u happen to replace yours and have the spring left over from your old line, keep me in mind

Is your power steering reservoir leaking? Take a closer look, if the power steering fluid is running down to the lines below. If yes, there is an o-ring under the cap to create a seal and over time that o-ring breaks down and as the power steering fluid gets hot, it rises/boils and spills out. Check the power steering fluid level as well.
