Hello guys!
Having problem on my s500 w220, year 2000.
Got "airmatic visit workshop" warning.
Scanned it and error that said "failty front right pressure relief valve" was erased, warning dissapeared.
Next morning i got same warning.
Then we did the same thing(scanned, erased) and warning appears right away each time now, not even a day like it was first time.
It still says "faulty right front pressure relief valve".
Took a look online, not happy with prices ($900-1200) for new ones and around $200 for used one (no warranty).

Also few times noticed that there is "pressure relief valve repair kit" online as well.
Im guessing this is a kit that can possibly fix faulty pressure relief valve?

Any help will be greatly appreciated guys, please let me know if you had same problem before.
Thanks!
Roman.
