I was also confused by the overfilling because our BMW systems would have errors in the instrument cluster/iDrive showing that. I'm not saying BMW uses these practices, but they exist. Also, based on the info 42pilot and another member posted, there is conflicting info between what is actually there and what the dealer says. I'm just making people aware to always tread with caution if you own your vehicle and start noticing random issues with your engine. Some guy named Eagle11 keeps going on and on in bimmerfest about how bad the 50i v8 is in other cars showing black smoke and what not. It could all be related. So far, none of us have had issues with our 50i, but information always helps, good or bad.

Actually no, I take that back. You can clear codes via ENET/OBD2 port software and clear oil change errors right from the cluster, so those errors can be hidden if a dealership is in fact using these practices. I really hope that we are getting the best service possible, but you never know. I'm sorry if this alarms people, but it's good to know what is going into your vehicle.

I would be extremely surprised if a BMW dealer were doing this. I suppose it has happened, but there is no way this is common. And clearing any overfill error message wouldn't do anything. If I had my oil changed at a dealer, then got an overfill warning, I would be back at the dealer and they would have to deal with it. Clearing the code wouldn't do anything, it would just come right back. If a BMW dealer ever got caught doing this, there would be big trouble. And they would get caught sooner or later. It just makes no sense.
