W212 2011 Estate suspension question

[Webseo69]

Hi all, do I have an Eclass estate and there is an issue with the height sensor. My question is that I noticed there are different Q numbers to the height sensors, what dies this mean? I think mine are Q7, can I install two Q5s instead?

Thank in advance.

I'm not sure what you mean by 'Q number'?
There should be a MB part number in the new and the old sensors. That will start with 'A............'.
MB do change part numbers when they revise the part.
I suggest that it is generally better to go with the latest part no.
Go into an MB dealer and the parts guy will give you the original & revised part numbers (if you ask nicely!!).
