and i have oil issues that i can not find from where they are i have a massive leaking on the floor on the drive way

You should get the oil changed and stop driving it until it’s done . It’s obviously low on fluid and likely you’re doing damage to it .

Is it leaking engine oil or automatic transmission fluid?

Regardless, any "massive" leak should be addressed immediately.

engine oil change before 1month
and transmission oil change after the new transmission installation before 7months
thank you for reply to me

thank you for reply to me the oil leak i find it and it was from the steering wheel pump one tube was cracked

I thought the GLKs had electric power steering, therefore no power steering fluid and pump to leak. Or was this only on the later GLKs?

Then again, I seem to remember my 2008 C300 had power steering via hydraulics, and the GLK shared most of its platform with the C-class. Perhaps the early GLKs had hydraulic power steering which was updated to electric for the later models.

Regardless, good thing you've found the leak and can now repair it. It might make sense to also check any other hoses in the power steering circuit; if one leaked, maybe others aren't far behind.

my glk220 its from 2010 and from bad luck its going with many problem and if some one has the same problem please let me know

What does the photo show ?

As with the reply from "Mmr1" ... those two photos don't tell us much, without explanation.

#1 ... what is in the spray bottle, what is he spraying at, and why spraying ?

#2 ... I don't know what the part is in that close up photo - can you explain ?

the photos show that i find the oil leak and the car its in servis and the botle its for the steering wheela fluid

Maybe something got lost in translation?
