E90 320D Oil cooler issues

[LYFGP]

[font=Tahoma, Verdana, Arial, sans-serif]Hi guys and ladies,[/font]

[font=Tahoma, Verdana, Arial, sans-serif]So Saturday, I was out working as usual.  Drove the car as normal.  I got home round 00:00 and parked her.[/font]
[font=Tahoma, Verdana, Arial, sans-serif]On Sunday I needed to go somewhere, but noticed some liquid laying on the ground.  I then opened the bonnet to check and upon closer inspection, on the bottom engine cover, it turned out to be oil.  I checked the oil level via dipstick and it was bone dry! [/font]

[font=Tahoma, Verdana, Arial, sans-serif]  I got no warning lights or any strange noises the previous night.[/font]

[font=Tahoma, Verdana, Arial, sans-serif]Anyway, Monday came, I had the car towed to a certain workshop (Name withheld as I don't want it to seem as if I'm bashing them).  Tuesday I called them to check up on the car and if warranty will cover whatever was wrong.  I got the shock of my life when I heard that my bill is R21k [/font]

[font=Tahoma, Verdana, Arial, sans-serif]So, the Oil Filter housing failed which I heard is a common issue on these cars, but the parts being replaced include:  Oil Filter housing, Oil Cooler, Oil cooler gasket, Gearbox cooler, Gearbox cooler thermostat, engine oil, oil filter, sump plug and coolant.[/font]

[font=Tahoma, Verdana, Arial, sans-serif]Does the above seem right?[/font]

[font=Tahoma, Verdana, Arial, sans-serif]My warranty only covers the oil cooler [/font]

[font=Tahoma, Verdana, Arial, sans-serif] , but I gave the go ahead for the repair as I was thinking that all these parts somehow play a role in the long life of the car and gearbox and if it didn't need replacing, at least it's done now.[/font]

Why replace the gearbox components as they are on a separate circuit altogether?

Oil filter housing leaks are common with age but usually the engine will throw a low oil warning before the dipstick would be dry. Good practice to change the engine oil cooler while you at it as they fail often enough.

How I missed this response, I don’t know

But anyway, not knowing much about why all those parts needed to be replaced, I gave them the go ahead. All seems 100’s still a few months later.

A few weeks before this happened, I had a random oil light pop up now and then and when I checked the oil level, it seemed to be fine still. Just to be safe I bought more oil from BMW and topped it up (obviously not more than needed) and the oil light never popped up for another 2 weeks or so… and then this

The oil cooler was replaced too thankfully.
