I Live in Kent (UK) and recently purchased an 8 month old F10 530 Diesel M Sport with auto. When starting from cold, the engine takes around 30 minutes for the oil temperature to reach 100C. My drive to work each morning is stop/start and steady driving...nothing unusual.

My car is booked to go into the dealer next week, but at the moment they say they have no idea what the cause is.

Has anybody else experianced the same problem..???

That's bad.
My 535d takes only a few minutes to warm to 100 C from a cold start.

Be gentle with the engine and take the car to the dealer asap. Don't wait another week.

Problem solved...got full refund of the car from dealer !

Good for you!

What was the problem?

Bloody hell! Musta been something VERY serious to buy your car back!!

It would be wrong to say anymore about the delear and circumstances, but it is back on sale to Joe Public.

Not know the problem?

The dealer and I have a differance of opinion. The car memory recorded no problems, but can you tell me why the engine took so long to warm up?

I was in a fortunate position in that i traded in a 530D for a 530D, so it was easy to make a comparison.

Huh! No black & white problem? How odd. I have no idea what it could be sorry. Well, my only thought would be that the Efficient Dynamics feature, "Active Aerodynamics" had failed. Ths is a vent that opens and closes behind your kidney grills.

"At the beginning of a journey, your engine needs more fuel when starting from cold. So to help ensure every trip you make is as fuel efficient as possible, Active Aerodynamics automatically closes the air vents to help your engine reach its operating temperature faster. This also helps improve aerodynamics, reducing air resistance to cut your fuel consumption even further. The vents are only opened again to allow the breeze to flow through the engine and braking system when cooling is required."

Unfortunately, because my 30d is housed in the E90 3 Series, there is no engine temperature display so I cannot compare with you but it does feel to warm up very quickly indeed.

Everything was checked including the sensor for the radiator slats.

The important thing is that i have got all my money back and have now ordered a new 530D M Sport with lots of toys...only 12 weeks till i get it !!

Absolutely. Was it BMW Approved dealer?

And congrats for the new order!

Happy Days!

Yes and NO I will never use them again. I could tell you more, but it would be wise to not to say anything.

I will tell you that I did email them asking if they wanted to quote for my new car, despite it costing £51.5K they could not be bothered to reply, hence my comments above.

My 530d is also 'slow' to warm up. I've just noticed this thread and thought I'd reply.
I'll have to time it but its seems like about 15 minutes or so before its getting close to the 100 mark.
its always that way and I assumed this was quite normal for 2 reasons, one its a diesel and and such , because it is more efficient and doesn't waste energy as heat. Secondly my car has a oil temperature gauge as opposed to a coolant gauge in my previous E39 and assumed the oil just takes longer to get up to temperature.

This behaviour is consistent and I have no issues with the engine at all, its very economical and refined.

i never give it the bean unless the oil is at or very close to 100.

Oil temperature gauges do show us the truth about how long a diesel takes to get proper heat into the engine.

From experience with diesel engines, with both coolant and oil temperature gauges, it can take twice as long, or twice the mileage, to get the oil up to temperature, compared to ECT. 16 miles is not uncommon for a diesel's oil to reach 100C a cold day.

Glad you got a result and understand your reluctance to go into detail, but can you say whether or not the dealer is anywhere near Tunbridge Wells?

The N57 shouldnt take that long to get up to temp. I havent had my car over a winter yet so cant give any ideas on cold temp warm ups but its certainly far quicker than my old M57N2 530d was. The oil temp in this car (530d again)is up to temp a fair bit quicker than the water temp reaching operating temp in the last car. With temps around here at 9 degrees this morning it was up to 100 degrees within 6 miles.

That is pretty fast, but a lot will depend on what sort of warm up running we do.

Even my N55 'inefficient' petrol engine wouldn't do that in my driving conditions, will take more than 10 miles to be 100C on the oil temp' gauge.

But my typical warm up will be 1/4 mile up the lane, one acceleration to about 60mph, 3 miles then 1/2 a mile at 30mph. An acceleration to 60mph and driving another 8 miles at around 60mph.

I'm off out in a few minutes, so will give particular attention to the oil temperature, ambient temperature today just above freezing.

No, it was not supplied by the dealer in TW. My new 535D was..

If mine was all town driving mine wouldnt be up to temp in that distance. My trips to work is around 7 miles with a little town work and about 6 miles of it over three different dual carriageways with traffic lights on them. I never get over 60 though so the engine isnt really working hard. Sounds like it warms up much faster than yours does though, does the 535i still use the old cast iron block.

My last car as we discussed before would have the water temp up to 88-89 in that distance even in winter. This car has the oil temp hotter than that in the same distance, will be interesting to see if the oil still gets up to that temp so quickly in minus ambient temps. Part of it must be the benefit of the alloy block warming up much quicker than the old M57 block.

Thanks for clarifying; I very recently bought my one year old 640i from JC, TW and reading your post gave me cause for concern regarding after-sales support.
I was pretty impressed with the service I received and the way in which my car was presented.

The N55 is an alloy diecast block, so no disadvantage there. But as you know, all our diesels have slow warm ups for the typical trips we do up here, so not expecting fast warm up, even in the petrol on a cold day.

Interesting on the trip this morning, as it was around 1C. I ran my IC recorder, so that I could replay the 'facts'. It took 7 miles to lift off the 70C marker and at 11 miles, when I stopped to fuel, was still below the first marker at about 90C. Just made the first marker (95C) at 13 miles.

Coming back home (45 mins later) it took about 6 miles to reach the 95C marker, and peaked at about 105C (ish) after another 3 miles.

Obviously warm up is much faster at higher ambient temperatures, but just shows that warming up the oil in a larger petrol engine can still take quite a mileage.
