Is there a diffence between MAF cleaner and EGR Cleaner?

[John77]

Hi I want to clean the MAF sensor. I have some EGR cleaner but not any MAF cleaner at the moment. Is there a difference?

I read recently that they were mostly repackaged carb cleaner . I'm not saying that is correct though , but I work in that assumption by using carb cleaner

EGR/MAF/Brake Cleaner - its all the same; high solvent content and no oily residue

Thank you. Also while on this subject where is the EGR? Do I need to clean it? W211 E200 2005. I have just seen a video on youtube and a guy is using oven cleaner. Surely this isn't correct is it?

Your EGR sits between the exhaust and inlet manifolds - but i dont know where - I cant point mine out yet!!
They do get quite clogged up over time so you wont know if it needs cleaning until you take it apart: but if it aint broke - id leave it.
I have heard oven cleaner being used, it would certainly get it clean - but i wouldnt!!!

In general MAF cleaning with a solvent is a waste of time and money.
The MAF is a hot wire sitting in the air stream and over time they build up a crusty residue on the outer surface. A solvent will rarely if ever remove it.
On some cars there is a diagnostic capability to superheat the filament to use heat expansion contraction to crack the residue off but that in itself is a fairly kill or cure cleaning technique as the increased heat can cause it to fail.

And then you get charged for a diagnostic as well

Ok So if I want to clean the MAF and EGR where are they on these pictures? Also does anyone have to service sheets for removal of these?
