I have a coupe 430xD model from 2018, 3.0L 190kW Diesel engine.
Since covid, I haven't been driving the car much, around ~10.000km in the past 12 months or so.
I noticed lately is that it takes really long time for the temperature gauge to come to a normal operating position. Thanks to all of the posts here, I did some investigation in the matter and here is the summary:
Driving condition:
1. outside temperature 14-15 degrees Celsius (not that cold)
2. driving in comfort mode with auto start/stop switched off
3. driving in the city, average speed ~42km/h and top speed up to 80km/h
4. no hard acceleration
5. summer sport tires Michelin 225/40r19 front and 255/35r19 rear
Results:
(see the attached table for details) - It takes about 10 min for the gauge to start moving from the cold blue area.
- It took 19 min. for the Oil temp. to reach 100 degrees Celsius and 14.7km
drive in the city with outside temperature around 14-15 degrees.
- The average fuel consumption is up from 7.3L/100km to 8.9L/100km.
Around the same time last year, same road (home to work) the Oil temp. reached 100 degrees after 4-5km drive and about 10min with average fuel consumption ~7.3L/100km
Car is under warranty still and BMW service staff member is assuring me that this is quite normal behavior.
What is your experience with 3.0L diesel engines?
Appreciate your feedback. |
The oil temperature seems to heat up in roughly the same time and distance as my 330d does in those ambient temperatures.
Also, If your coolant temperature is staying at 90c+ once fully warmed up and not dropping back down when the engines on low load the thermostat is fine.
