If there is a coolant issue that causes engine overheating, you will see this on the oil temperature gauge.
Well obviously, eventually you will. But it will take a longer time for that heat to transfer to the oil than to the coolant.
I was pointing it out in reply to the OPs initial statement that the engine overheated but the temperature gauge didn't move.
I wanted him to fully understand what the instruments were showing that's all.
In the 'good old days' you would have a water temp gauge, and as an auxilliary an oil temp gauge, just for bragging rights. BMW have just confused the issue by fitting an oil temp only gauge. I fear it may be an upshot of their engines being very sensitive to oil circulation issues when cold.
I suppose it makes more sense waiting til the oils warmed up before leaning on the engine, as opposed to the water temp.
Oil takes longer to come up to temperature :thumbsup:

Which is it on the N52? It comes up to temperature very quickly, so I always assumed it was coolant.

2E82 and 2E81 auxillary water pump switching off/speed deviation - intermittent

Shame the breakdown company showed no error codes.😩

Just pricing up parts 👍🏻
Bummer, so sounds like the water pump has given up the ghost?
Out of interest, how many miles has your car done?
It's done 63k.
