Lane monitoring is different from Active Blind Spot Assist. You have Active Blind Spot Assist if your side mirrors have little triangle warnings in them. They are activated by radar $ensor$.
Lane monitoring tells you if your drifting in and out of your lane, but I haven't seen an R equipped with it.
I don't think you need Star/Das to troubleshoot which of your parktronic sensors have failed. But you will need to have the car plugged into a quality OBD tool, something a good MB indy would have.
