We have already tried bleeding the system and that does not seem to work. All the bushings under the car are solid as the day it was built so I think it may be time for new shocks. My car is a US model and has never given me a moments headache since the day I bought it. Also, if anyone has eliminated the self leveling system...please let me know. For the two a**holes who cannot post a decent coment...go drive a pos bmw and for the guy telling me I don't know what I have...I know what I have because I paid for it so I know exactly what I own!
