Long time for engine to warm or not?

My E93 N54 seems to take a very long time to get to running temp. My other cars seem to move the needle after just a few minutes. My BMW can take 10 minutes or 4-5 miles to even approach running temp. How long does yours take? Is mine normal or is the t-stat stuck open?

Thanks

The temp is oil temperature, not coolant temperature.

Mi E92 330i always takes a good 10 minutes to warm up, anything between 5 and 10km depending on speed.

My car's temp needle starts moving up after 8km (10+ minutes) even in hot summer.

As noted, it's oil temperature, not coolant. My E92 with an N54 would take 2 to 3 miles before the needle began to move, 5 miles (3 at highway speeds) before the temperature would reach 160F, and between 20 to 25 minutes on the highway to reach full operating temperature. The temperature increase in my F22 with an N55 is similar. It's the nature of the beast.

FWIW, general consensus is to stay off boost until you're over 160F if possible.

My N52, while lacking a coolant OR oil temp gauge, I would say doesn't "warm up" for several kilometers, even in the summer. In the winter I'll give it a 10min idle warm-up before even driving off. I stay off the throttle during this time as well, feather it as much as possible.

My N54 is slow to get to maximum operating temperature for the oil. Depending on the ambient temp and how fast I'm diving, it can take quite a while. However, the coolant temperatures rise pretty rapidly. I notice it in very cold weather. It does't take long to get warm air into the cabin. The N54 engines runs pretty hot. I wouldn't worry about a slow rise in oil temps.

All you guys who are having long warm up times 2-3 minutes+ you need new thermostats. These cars have an electronically controlled thermostat and when it fails it fails open so it takes a long time for the car to warm up. It also doesn't produce any lights on the dashboard and it will only show a code if you a reader that can scan all codes. I would suggest you all go somewhere that can scan all the codes properly it should pop up. 10 minutes is too long, because the water pump and thermostat is electric it should actually heat up very quickly. My N52 engine use to take 10-15 minutes for the idle to drop to its normal ~600 (no temp gauge) after replacing the thermostat it would take literally 2-3 minutes.

2-3 minutes is way off. I recommend you to check the coolant temperature in the hidden menu of the instrument cluster and measure the time from engine start to 90+ deg C.

I cant remember how long it actually was and I've sold the car since. The point I was trying to make that if its taking anything longer then a minute or two it's probably the thermostat stuck open.

It is closer to 15 min with a good thermostat.

I could never actually tell as the stupid car didn't have a temp gauge all I knew that it took like 20-30 mins for the idle to drop to what it should be and after the thermostat swap it took like a minute or two. What the temperature was though I had no idea.

The idle drops sooner.


Here is my data for the E46 M56 2.5 engine:

(I don't have the time when I started the car but the rest is there)

8:19AM; coolant: 44 deg C; engine oil: 27 deg C; radiator outlet: 10 deg C
8:23AM; coolant: 61 deg C; engine oil: 41 deg C; radiator outlet: 10 deg C
8:25AM; coolant: 69 deg C; engine oil: 51 deg C; radiator outlet: 10 deg C
8:29AM; coolant: 79 deg C; engine oil: 64 deg C; radiator outlet: 10 deg C
8:32AM; coolant: 82 deg C; engine oil: 71 deg C; radiator outlet: 10 deg C
8:37AM; coolant: 93 deg C; engine oil: 80 deg C; radiator outlet: 45 deg C
8:43AM; coolant: 94 deg C; engine oil: 91 deg C; radiator outlet: 24 deg C


So the engine oil warms up slower than the coolant. This is why people with oil temperature gauge think their car warms up too slowly.

Dude that's a very different engine. The engine warms up very differently in the N52 and N54/N55 because they have an electric water pump and thermostat not a mechanical one like the M56. I'm pretty certain it will warm up way faster then you M56.

Yes it will be faster. For the M56 coolant it took more than 20 minutes to reach 90 deg C. For the oil it's past 25 minutes.
So my guess is, the N52 will reach it in 15-20 minutes.

All these people are driving 335s with N54 engines and are looking at the oil temperature, not the water temperature.

Water temperature comes up quickly. The oil takes much longer, in the range of 20 - 25 minutes to reach 240F on the N54 in my E92. Same on the N55 in my F22. From day one. Never a code to be seen, because, you know, it's normal.

I don't believe anyone said "too slowly". Someone looking at his oil temperature gauge asked if a long time was normal, and was told it was.
