M6 E63 oil level sensor

[noble1978]

Can someone please tell me where it is. I have an intermittent fault where the oil level can't be read, it says I need a service and the oil level temp goes fully to the left (low). I think it's the sensor itself or wiring to/from it but don't have a clue how to find it!

It is bolted to the bottom of the sump, and an easy DIY replacement, but the oil has to be drained out. Check the connector isn't loose first. You'll need to remove the undertray to gain access.

Assuming it isn't an BMW-only part on this engine, I wouldn't use a pattern replacement, they have a habit of failing!

Failure of the sensor seems to be a BMW trait. The level sensor also measures the temperature, so explains why you get the low temp display. The pressure (red light) is monitored elsewhere, so if you get the *pressure* warning, stop immediately.
