road and track I think said new 3 series BMW has a diesel option- strong and fast, good mileage, BUT to meet emissions it carries a tank of Urea liquid which is injected over 15000 miles, when it runs out you get 3 or 4 warnings then car will not run at all. BMW guy said "well you will be in at the dealership getting the 15000 miles service so no problem--- Oh yeah?????

Isn't Urea plural for urine?????

I read about that a few months back.

It acts like some kind of catalytic converter on the diesel. A new emission device that without it would not be allowed to drive on the open road. More efficient engine with different exhaust byproducts or something like that.

Anyone know how much the 15k mile service is?

I think I read that Ford has the same thing on their F series diesel pick up or will very soon. It would certainly be a cost saver if one could refill the container, oh, let's just say naturally.

What does it cost to refill every 15,000 miles?

And can you just pee in the urea tank by yourself?

You can or soon will be able to buy the stuff at truck stops. All those semi's need it.

It shouldn't take long to start flowing.

SCR has been used in thermal power stations for an age, so it shouldn't take long for it to start slipping out of that production.

People have been bypassing smog devices just months after they get invented.

I am willing to bet $100 that within 1 year, someone will shut off their urea system.

I really have nothing against urea, it will be available at truck stops at competitive prices in 2.5 gal jugs within 1 yr since all the truck mfgs except Navistar are going to it.
I do have a big problem with EGR because it degrades the longevity of the engine and the oil. And it INCREASES particulate production.
And I don't like DPF either because it costs fuel.
So I took the EGR cooler off my 05 Unimog which returns it to Euro III emission levels and economy.
If you own a $60K BMW X5 35d, the cost of urea shouldn't be too burdensome.
