Engine warmup countdown indicator

[GoKuA]

Does anyone notice the engine warmup countdown indicator in the instrument cluster isnt working? Mine doesn't count down, it just starts right at the last yellow indicator even on the first start up.

Mine works, it starts at around 6000-6500rpm.

Same for me.

Nevermind, after a few days of observations and I noticed the indicator does work. I freaked out too soon.

do you park outside? Just a theory but if the car is warm from LA sun or warm weather would it start higher vs. weather in the northern climate where it tends to be cooler?

That might be the case. I don't park outside but inside my garage is hotter than outside temperature, especially at night. I didn't drive the car for a day and the countdown indicator was at 6k rpm when I first started the car this morning.

Where is the indicator? RPM lights? I haven't noticed anything like on the E90M.

Bad theory.

I can park my Cayenne outside all day in the blazing TX sun, start it up, and still see oil temps of less than 80 degrees. Water temps are around 100 and come up QUICKLY, but oil temp still takes a while to get up to temp, despite atmospheric conditions.

I'd love more info on this, too. How does this work? Where's it displayed?

How can the oil temp be lower than the air temp? Just curious.

Because it is not directly in the sunlight being bombarded with energy causing molecules to collide. Instead the oil sits in the engine with lots of parts keeping the oil away from being directly exposed to the sunlight.

I understand your point that it's not getting heated by the sun.....just seems odd that the oil in the pan can get cooler than the air temp, sounds like magic to me.

Put a glass of water of hot water the shade outside or under your car for a few hrs, if the temp of the water is significantly cooler than the ambient air temp I'll be shocked.

water has a different molecular structure than oil. lets not mention that some chemicals are prone to heat more than others.

Is there a practical purpose to this info? It is not recommended to wait for engine to warm up. Per manual, start and go.

Because it's not sitting in the shade, exposed to ambient air like your example. It's inside a large metal housing, Which is further covered by a plastic shield. That means that the ambient air would have to penetrate the shielding (somewhat easy) then heat the oil pan up (much harder) enough to heat the oil to ambient.

I too don't understand how the oil could be cooler than ambient air temperature? If its 100 degrees outside I would think the oil's temperature sitting in the pan would eventually normalize to 100 degrees also, not 80 degrees. Maybe for a few hours in the morning the oil could retain cooler temps than ambient as it heats up slower than air temp?

Maybe the oil temperature gauge in the Porsche is inaccurate?

Wait, there is a warm up indicator in the LED shift light? I dont think i ever saw it works and thought there is no such thing like in my old M3.

There is, but it's not the analog style in the E9x. It's back to the E46 digital style, where shift and warm up indicators share the same LED lights.

Hum, I didn't notice the warmup LEDs when I first got my car and thought it is no longer a feature. I haven't been paying attention to it. And this morning I am didn't look for it again. Now the car is all warmed up and am at the dealer for the 1200 miles service. will have to really look for it next them I cold start.

It's very subtle, not as noticeable as my previous E92 and E46. That's why I thought it wasn't working at first until I really paid attention at the first start in the morning.

Look man, I am not going to argue this point with you its not worth it. If your saying that BMW uses some magic oil that will stay cooler than the air temp because of the molecular structure that's fine, but I am not going to believe it.

If a car sits in 90 degree heat (in the shade or in the sun) and isn't driven for awhile do you really think the oil will somehow be 60 degrees in the pan?

What specifically in the oil or structure of the car has the ability to cool the oil while it's parked?

I am not an expert but I can't see how the oil can be 20-30 degrees than the air temp when it has just sitting for a period of time.

Anyway - if you have some examples to share great I am happy to learn more scientific facts - but if your just a "guesser" and trying to dispute my logic based assumption - I will just tune out.

No offense just don't think you point makes sense. but your determined to prove it with no evidence.
