Hi guys! I just bought 2 weeks ago a 2016 BMW 5 Series F10 2.0 diesel xdrive 190HP (B47) with 51 000 km on the clock (~31 700 miles) and I have two questions:

1. My oil temperature gauge never hits the 100°C mark. Is this a normal behaviour? Even after 200 km (~124 miles) of driving it doesn't hit the half mark. If I put it in Sport Mode the oil gauge goes down at almost 75°C. I saw on some YouTube videos of other owners that the gauge stays right on the half mark. The maximum that I had is shown in the attached picture.

I have to mention that there were only temperatures under 10°C/50°F.

2. Is there any recommandations related to differential/transfer case oil change for the xdrive system? Or if is there any resource available where I can see what maintenance does this car require?

The car is awesome, I just want to be sure everything is ok. Thank you!

Not sure about transfer case but as far as engine oil goes, on a 3l f10 it never crosses 100. Maybe it gets a little closer but not by much compared to your picture. Hope this helps.

My 2016 520d 190hp B47 hits 100°C bang on, both in cold and warm weather.

Thank you! So I guess I have an issue with the oil temperature gauge. I will try to investigate this further. Maybe someone encountered this problem and I will receive more answers here.

I believe that is normal. On my 2014 gas powered F10 the oil temp has never hit halfway, even in over 100ºf heat.

The gauge is normal, and for the other question you can search this forum, there is lots of info available!

[philipm785]

Agree - my temp gauge usually looks like yours.

[snakri]

Thank you! My only concern was if it can lead to premature wear if it can't reach the optimum temperature. It's a little bit weird indeed that at some cars the gauge stays on the halfway mark and at some not.

My 2016 B47 190PS (RWD) hits exactly 100.

Curious... Are there different oil coolers installed with the xdrive version?
Or different oil is used?

[snakri]

I'll wait, maybe someone solved this issue or has more info about it. Thank you!

[ezaircon4jc]

It's normal...

[octgab]

Of course is not normal. It should be always at 100 mark. I have the same issue now. Its been at 100 for the last 5 years and now sits just under 75

Chiming in a little:

F10's come with two different types of oil cooling. Coolant-to-oil, or oil-to-air. The former depends a lot on your coolant temperature. Log your coolant temperatures and make sure they're not shockingly low, usually due to a bad thermostat. The latter is divorced from coolant temperatures and is regulated by an oil thermostat.

Coolant-to-oil (silver block looking thing):



Oil-to-air (two lines coming out):

Another thing to point out is that gauge on the petrol va diesel engines is different. On diesels it is supposed to hit the middle based on the scale used. On petrols the scaling is different (ie numbers on the gauge) so it’s supposed to be little to the left of the middle.

Mine is a petrol 535i from Canada and middle is 120c not 100c like in the diesels.

Hello!
I do have a issue regarding my f10 B47 2015,the temperature gauge seems to lean 1-2mm to the right,as far as I know it should stay dead center and not lean to the side,please note that a hard acceleration in Sport for example will make it drop significantly.
My question is if this Is normal since I heard that it does this in order to get better emissions/consumption.
Thank’s in advance!

[Breach]

Certainly not normal, and also note that the gauge doesn't really display the proper oil temp. You may have a failed thermostat (fails open). Since it's a diesel, that may lead to a blocked DPF quite quickly. Take it for a check-up.

Breach I did take it to two separate mechanics,both tested it and all appeared to work fine,they even cleaned the radiators and changed the coolant,after that one of them told me that this is normal bc the car does this for better emissions plus consumption but I didn’t really buy it.
So you say change the thermostat and see where that goes right?

I also have to mention that I have a ongoing recall for this car regarding the EGR valve (still waiting for the parts)

The usual cause is a failed thermostat, yes. Could be something else, but honestly nothing else comes to mind. A closed/blanked EGR would also lead to slower warmup, but it should still come up to speed.

Dunno why they changed coolant - your problem is too much cooling, not the other way around?

These mechanics, did they at least read codes?

2013 F10 xdrive with the heat exchanger at the oil filter housing. Middle of the oil temperature gauge is 250F.
Normal for my car is slightly below 250F, which matches the owner’s manual:

“Normal operating temperature: the pointer is in the middle or in the left half of the temperature display.”

[BarbeCan]

Breach I will change the thermostat and come back with updates regarding how that goes,thank you!
