Where is the Alde expansion tank? 2014 320S

kstoo · October 2025

I read in manuals and online about checking the level of the expansion tank but I can not find it. I have taken apart everything that I can looking for it but to no avail. Where is it? Please give me a clue.

Also, there are points to bleed the system. I have no clues as to where those are.

Welcome to the Forums.

Here is the expansion tank location thread. Under the "driver's side rear shelf".

The legendary bleed valve may not ever be needed, despite all the attention it gets. In my 2017, the bleed valve was buried so deeply behind the back cabinets it was unreachable unless you took the rear bench out, and even then you couldn't see it well enough to adjust it. On the 2017 models, the bleed valve was on one of the glycol hoses under the back bench where you see the hoses come out of the back wall.

Well, alright. Problem solved. It wouldn't be that difficult to add this information into the user manual but that is just the way that it is ... thanks!
