I have a 2008 BMW 328i..

Wondering is there any way to change the oil temperature gauge and make it engine temp??

And since I only have an oil temperature gauge how would I know if my cars engine is getting hot?

Thanks in advance🙂

The oil temperature and water temperatures are the ones you want to know.

The engine varies temp based on location and so that’s not really useful data.

Okay but if my engine is getting hot let's say I don't have any coolant would it tell me?

I would rather have a temperature gauge!

And also if my car is getting hot will the oil temperature gauge go up? What's the acceptable range?

You do have a temperature gauge and it’s more accurate than a random point in the engine bc the coolant and the oil touch almost all parts of the engine.

You will get a coolant low light in the dash if you don’t have enough.

You will get an engine temp warning if the “engine”, aka, the coolant gets too hot. There are two. Yellow light is too hot. Red light is way too hot.

The engine will also go into limp mode if overheating.

The acceptable range is what’s presented in the gauge. The oil will degrade quickly at 300, and it’s not normal for it to reach that temperature.

Thanks!

Yeah my oil gauge has never gotten more than 240 even with me running it hard or in traffic It usually sits at 230.

By the way no one's been able to answer this question do you know how to get rid of the startup BMW chime or how to lower the volume it's pretty loud and scares me at times!

I have the bimmercode app

Volume is in you navigation. But yeah you turn it all off. I know ProTools can do it. Dunno about BimmerCode, but likely.

GPT the modules where the options are located.

I don't have navigation, only a radio! :-(

Why don't you just accept the car as it is? It's a 20 year old platform with hundreds of millions of miles driven by several hundred thousands of owners and none of them really had a major problem with the car related to oil or coolant temperature or the volume and purpose of the warning chimes.

With my E90 its service life was being driven 165 miles a day for nearly 15 years, driven hard on back country roads and sitting in heavy stop and go traffic. My 2006 E90 had neither a coolant temperature gauge or a oil temperature gauge.

Why keep trying to change it? Accept the E92 for what it is, which is one of the stoutest cars BMW ever produced.

Ok yes sir I will try!!

I have car with coolant T°, and imo is a bit useless, since the T° rise uber fast when thermostat is closed, and reach the setpoint quickly.
Even if I wanted to use it as a overheat warning, again not worth it, because the car will overheat in few second and trow a alarm before I can noticed it on the gauge.

Now, you want the oil T°, since this is the indication to WOT the car.

While my other car I can only guess the moment when I can beat on it.

Okay I understood some of that thank you!

But if my car was overheating will the oil temperature go up to? Mine usually stays at 230 no matter what!

no.

because the coolant overheating will be way faster than oil temp rising .

according to internet 1st warning is 248F and last warning 266F. When the flow stop for any reason, the T° rise fast af. oil inertia will take time to get to this limit.

Might give you a early headups, but at the end, unless it's -20f outside, the overheat alarm will warn you to stop the engine safely, and you probably need a towing anyway.

When your car starts to overheat you WILL get an orange coolant temp warning on the dash, once you are into the overheat territory you will get a red coolant temp warning on the dash....also of note you will get the BMW DONG SOUND to alert you to get to look at the dash for the temp warning. Its literally by design that the dong was put in to alert you to look at something important. The car will also attempt to protect itself my going into limp home mode for a little bit

Not to mention that the oil temp is a CRITICAL piece of data for a car that is being driven hard. When a car is being driven aggressively or on a track, its not unheard of that oil temps could climb while the coolant temps are fine. This is why the 2008+ turbocharged cars received an external oil cooler. The reason you don't see it go above a certain temp is because your car is literally targetting that specific oil temp and adjusting coolant flow, volume, etc not just by opening and closing the coolant thermostat, or the oil thermostat on cars with external oil coolers, but literally by increasing and decreasing coolant flow via the electeic water pump to keep the car in the very specific temp range.

There are some GENIUS level engineers that worked to design the car in a very specific way, stop F'ing around with it as you are way more likely to introduce issues into the electrical system that you will not be able to fix. Instead of trying to f around with all the car's electrical systems, you should go fix your car's VANOS issues that you posted about on another thread. That is WAY more critical than this crap you are fixating on.

Anyway sorry for the rant, but just go enjoy the car. Let it continue to be one of the best platforms ever made.

Cool thank you for the info!!

I never saw those codes again, cleared them and never came back, only did it once- that is stalled!

You're new here and based on your few posts, know nothing about the E9X platform. You found a gem of an E92, a manual with just 77,000 miles on it when the car could have over 200,000 miles on it if it was used regularly (10,000 - 12,000 miles annually). I lot of members here would love to have found that car and they would be smart enough to preserve it rather than fuck it up by modding it. It's a great car out of the box and really needs no improvement. I've politely suggested you should just leave it alone and not molest it with modifications that will not add to the enjoyment of driving it.

In another thread you've already cut out the charcoal airfilter in the airbox which is completely unnecessary. It wasn't clogged and wasn't restricting airflow. Apparently, you are not satisfied with the performance of the N52 if you think removing part of the intake system was going to gain horsepower. You don't like the warning chime built into the user interface and you don't like that there is no coolant temperature gauge but there is an oil temp gauge.

If you want some additional horsepower the only real option is converting the engine to the 3-stage intake manifold, which is not expensive and requires a tune to the ECU. That mod is already engineered by BMW and does not detract from the original intent of the car as designed.

Seasoned owners here have tried to explain to you the E92 has other notifications that alert the driver to an over-temp/over-heating event. Part of that system is the chime that you find offensive. The changes you seek to make on your E92 are acting in difference to how the car was engineered and designed to interface with the driver. Many of us have lots of experience with the E9X platform and have told you it works well as designed. Any of the mods you are contemplating or trying to make are not going to improve it. They will change the car, but they will not improve it.

I suggest you consider the advice that many of us are giving you. You are lucky to find such a low-used sample of an E92, you should preserve it rather than screw it up.
