Directed at earlier cars with hydraulic fluid and Porsche's stupidity. Lucky for us that they did go to electric since they did such a poor job with the hydraulic system.Even more so people are never checking the power steering level because for that you have to remove the engine cover plus for some dumb reason Porsche doesn't have a low level sensor for the power steering thereby destroying the whole power steering system from the rack back.
Didn't know they didn't want you to check coolant level until light went off but it seems very strange to me that a car would use that much coolant. I've never had a car that used more than a few ounces. Usually it goes down from max to low level and stays there. At least that's what I've always noticed.
