seat compressor / random hose for dynamic seats

[jbbuff]

evening guys
I have found a hose not connected and no place for it to go from the chamber on the inner wing!
I have 3 hoses in the black chamber and 2 from the compressor but have a hose not connected and can't find any info on line ?

Hi
The hose in the photo is over pressure valve and doesn't plug into anything.

many thanks while its good news it means there is still a fault after changing the compressor
i see a post regarding some kind of solanoid or power pump not connecting the guy had taken a few of said units a part to clean contactors and cleared the problem don't suppose you would have any knowledge of such a thing as my local german specialist and an auto electrician have no idea and im only getting no or low pressure codes on both seats ? regards

Hi,
You can try fixing the pump, but all the utube videos and successful HOW TO's to repair these pumps I found are not the same as the ones in the CLS (Unless of course you have found some).
Have you got the exact code no.'s and code description? Was the car plugged into a STAR diagnostic computer?
You say you replaced the pump, was you're original pump rectangular? (early pump) what shape is you're new one? exactly the same? as the later pump is more cylindrical, the early pumps failed as they overheated inside and melted, additionally, just because the pump is running doesn't mean it is producing enough volume of air.
Additionally you're air bladders in the seats maybe leaking, and this can also lead to low pressure air fault codes.
You can pressure test the bladders in the STAR Diagnostic Computer
Most people give up trying to repair the Dynamic seats as it becomes very very expensive especially if they haven't got easy access to the STAR Diagnostic computer.
I ended up replacing six of the air bladders, the pump two times with the original early pump, once with the later pump and all were not producing enough volume of air, then found the later modified pump brand new on ebay, then I had to buy a modified piping loom, foam box and new mounting bracket.

oh crap and i dont believe it was a star unit it was just an auto electrician with a troncrom unit i thin it was both seats come up with no or low air pressure.
the compressor i changed was exactly the shape as the old one in the pic attatched also have papers for £1000 on repairs but can't read it very well back in 2018 !
Tbh i'm not that worried if its going to be a money dump as id rather put that into other areas of the car..
