Murt Ommukas

I selected dynamic mode to lower my Audi A6 suspension. Suddenly I saw that the suspension was too low on my wheeles. I tried to put suspension on lift mode, but for a minute the MMI controls are okay, but then they grey out and the suspension doesn't move at all. Also I have yellow air suspension light and green suspension light in my dashboard. Does anyone know, what the problem could be linked to?

I ran VAG-COM and got error:
02646 - Plausibility of Level Control System
008 - Implausible Signal - MIL ON
