Yes I noted the actuator on the water pump and commented on it in the other thread for the B48 engine. Having some sort of flow valve definitely indicates a flexible cooling strategy.

That and the electric turbo cooling pump makes some sense.

Time will tell if this new design is better/worse than N55.

A deal breaker? I understand why you may be concerned, hopefully BMW have gained a complete understanding of why we've had the premature timing chain failures, (particularly in the N47 diesel), and have designed the problems out of the new engines.

I don't think BMW have any other option than this split design, with timing at the rear and ancillaries at the front. Their explanation has (in part) been to keep the engine installation lower at the front. Low body lines and pedestrian protection systems all being part of the design requirement.

I'm sure there are NVH issues as well, which suit the design, particularly with 3 and 4-cylinder designs with higher torque outputs these days.

What a stroke of genius - pull the engine to change a timing chain. While I generally like the car, I'm really starting to wonder what the logic is behind some of their engineering decisions.

When I decide to replace my current ride (right around the time the MY2017 models come out), I will definitely be checking the competition for equally stupid features. No spare, no dipstick, useless center console (I should have caught that on my own), back up camera that's at least as good as a Ford, a radio display that shows exactly what Sirius broadcasts, a voice command system for the radio that understands "Fox Business" or "60's" rather than requiring me to memorize the station number (again, like a Ford), etc.

Crap, now I've whipped myself into a mini-frenzy and may start shopping early.

It might be. I can hope that BMW learned how to build a reliable timing chain. And that someday they can build a reliable window regulator. At the very least, it will keep me from jumping on a 2016 or 2017 model, until I see how they are holding up with some higher mileage cars.

I don't see the charge air cooler, did OP mean to say intake manifold?

Looks a lot like their diesel filters.

Hey E90Fleet,

How closely does this setup match the B48?

Very similar, with many common parts.

Yes, that was the intent of going to a universal, modular design for the 3, 4 and 6 cylinder engines. Saves BMW loads of money on parts, design costs, manufacturing issues, etc. Whether it makes the most sense for performance and economy remains to be seen.

Yes and it looks like you need a FORD!

My screen shows me what I'm listening to. Lots of cars don't have spares now. 99% of the population calls a tow truck anyway. And WHO cares about a dipstick?

You have obviously NOT seen what Sirius actually broadcasts. You might want to check it out to see what you're missing - lots of graphic stuff BMW just can't seem to capture. Just because "lots of cars" don't have a spare doesn't make it a "good" thing which you will find out if you ever rupture a sidewall - if it happens to your spouse or daughter, you'll likely end up having spare stuck in the trunk whether you like it or not. Call a tow truck? Yep, I've got nothing better to do but sit on my butt for hours waiting for one to show up. Dip stick? Some of us don't place all our faith in unnecessary electronic technology when a simple dipstick works every single time without fail.

I know it's blasphemy to point out BMW shortcomings but, I have paid the entrance fee so I'm entitled don't you think?

Then go buy an Benz. You obviously can't be pleased.

Response is close but needs to be changed to "You can't be EASILY pleased."

Piezo or solenoid injectors?

My 1.0 Focus turbo has a separate turbo cooling system. The electric pump runs for a few minutes after you shut the car off (among others times, I'd assume).

I also believe the new Lexus NX200t has a unique turbo cooling system.

Yeah, I'd guess a lot of cars have it now. Seems like a good idea - if it's durable.

Does this this mean no waiting a minute or two for the turbo to spool down?

You don't have to now. The pump runs on the n55 n54 and n20 after turning off.
