Thanks for information. My one got message "Brake servo restricted" only 3 months ago during my motoway driving. and disappear after I stop and leave it after a night. So I ignore that. However it appear again this morning. found the topic here and go to AUDI dealer to got parts. change it and all ok now. hope not damage the ABS system, just hope. BTW. the dealer give me the 5Q0906207, not 5Q0906207A or 5Q0906207B. might be different version for the car. not sure why. looks like same.
