E39 M5 oil temp and coolant temp off the scale
Discussion
When running too cold the ECU will make the car run very rich, as said then will cause poor fuel consumption and loss of performance. It will also soot up the plugs and cause extra wear as the oil will be too cool and thus too thick to flow sufficiently through the small oil ways to lubricate things fully.
If you plan on doing the job yourself, which is not too hard, I would recommend getting at least twice the number of O rings you need, both sizes. It's very easy to pinch and split these when you refit the thermostat housing. A bit of Vaseline or antifreeze on the rings helps a bit, but it's still advisable to have some spares.
OK, well get the garage to have some spare O rings in stock! Or get some yourself from a dealer or BMMiniParts and put them in the car, when the garage ring you and tell you that there will be a delay due to the damaged O rings you can the tell then to use the ones you have! Two spare sets should be enough.
So yes then. I'd have thought they'd have calibrated it for the S62 so that the needle would sit in the middle.
Not that it's a big deal, it can lead to some confusion though when you're new to the car and are used to hearing about identifying a dodgy thermostat by the needle never reaching 12 o'clock.

You'll want number 9.
