Interesting design. In theory if the engine was ever run out of oil and there was no prior indication of low oil level. Mercedes benz could find themselves in small claims court for a new engine. The onus for engine oil level responsibility may now have shifted to them. I am assuming the oil level is tied to an engine shut down system as well. Unknown failure of this system is going to make some owners mad. I can almost see the threads of the future. Lets examine one possible senario. The shutoff circuit has failed with age. You do not know this as you have never had low oil. The low level dash indicator bulb fails. Or if you have a constant level indicator it has failed but still reads normal oil level. You then get low oil between changes because a front seal has started to go or have developed some problem like a bad gasket. You land up with a damaged or seized engine. . It is well recognised that a oil pressure light coming on at speed is sometimes too late. Now who is responsible for this train of events? There is no way you did not apply due dilligence. Then the kill ciruit if functional will not work either. They hopefully have also equiped this engine with a separate engine kill ciruit on the oil pressure function as well for safety. Again if this overall system fails to function properly and it results in even an older out of warranty car loosing an engine it might allow a court proceedure. A simple dipstick assembley would keep them out of court. I think it will be back. How many guys are going to spring for a new computor because the oil level function is out as well as those cars age?
