BMW had a sketchy past with all plastic, from impellers to other items like washer bottles, radiators, underbody panels, interior trim pieces, etc.. It just didn't age well, got brittle and crumbled.

I'm told by several people their plastic has improved since around the time the E90 was introduced. Personally, I haven't had issues with brittle plastic in years. And a family member has a 06 E90 and hasn't had any significant issues with plastic crumbling. On the other hand, in that 06, power window regulators......

Agree..The water pump on my 335d was fine and it was a mechanical.

Wow. I hadn't seen that. It doesn't make sense to me. I've read more than one report that says BMWNA has come to regret not importing the F11.

Yes but it also has the 802.11 N instead of just the 802.11ac for greater communication between the pedal and ecu input adjustments.

The driver experiences faster throttle response.

You got your .11 protocols backwards. Please be aware that this is going to result in your car going in reverse the next time you try going forward.

It's not the engine, it's the power it makes. I drove a M235i and it just feels slow. When I drive my 335i with Power Kit and the stock engine mapping it feels awfully slow.

When I buy a car I always look into tuning options in order to get more power than I could afford in the first place. A 3 liter turbo engine should allow me extra 50hp for $1000-$2000, otherwise I wouldn't consider the purchase a good bang for the buck.

Very informative, thank you for this!

Me too. In fact he was insistent that it was a waste of money that would be of no real value. I bet we were not the only ones to hear that speech. Wonder why they would try to dissuade people from adding more options and raising the bottom line?

Nice try on the joke, but AC is faster than N buddy.

I doubt it's more than a dollar in their pocket. More like they feel they are doing you a favor by recommending ways you can "save" money that you overlooked.

Like: "You don't need to pay extra for that underbody rustproofing, BMW already has that covered".

Not addressed in the document. Both suspension and the EPs have been tuned differently.

[Tr1ppy]

Hi all,
Not sure if this is the right place to ask, but does anyone have a link to a similar document for the N53 engine please?

Thanks

I wonder what motivated the return to a belt driven coolant pump. Seems like a step backwards.

IMO with regards to the N54/N55 the electric pump was intended to move coolant through the turbos. Now that the turbos have their own failure prone electric pump the block can revert to belt driven.

They need to order a new TCU. That should solve the problem.

This issue has been on almost all of our 2016 2/3/4 series inventory, and late 2015 2/3/4 series inventory.

Could you help me out with any technical documentation about this problem? I'm fighting an uphill battle because I'm US Air Force stationed in Italy, and I bought the car through BMW military sales. I keep getting conflicting reports about whether or not the TCB2 will work here. Knowing this issue exists makes one more variable to tackle before we can develop a solution to using North America TCB2's in EU and vice versa .

I'm up in Germany with the same deal you got and a 340i. I'm getting a resounding 'no' from the dealer and coders.

I can't say for sure if I had the exact same problem, but its symptoms were similar: none of the functions requiring comms over the TCU's cell modem would work. My car is a 7/15 build, Euro Delivery. The fix didn't require any hardware replacement, just a software update. Solution details are here: http://www.bimmerfest.com/forums/sho...d.php?t=870002

Yup. It's a software fix.

Does anyone have information about this new class of engines being less prone to that ugly carbon buildup in the intake plenum and valves??

the electric water pump breaks a lot..

Oh no if you know the symptoms then the electric pump on the N55 (in a E90 335i at least) lets you know early that failure is pending.

Based on member experiences (including my own) on the E90 forums. If your N55 is at around 50,000 miles:

1. You get at least one momentarily false ENGINE OVERHEAT warning on your dash (with some cars going into LIMP MODE requiring a restart of the engine). When this happens the first time (since it may recur a few times) you have about 100 to 500 miles left of driving before total failure. A lot of people may miss this dash warning since on some cars it can flicker on for a second or less however the next symptom is hard to miss.

2. Inside 50 to 100 miles of failure the engine fan will become extremely loud when the car is put into park before the engine is shut off or when the car is stopped briefly in traffic (red light, stop sign, traffic jam).

The drawback of the electric pump is they fail earlier than water driven pumps and when the fail they are VERY FREAKING EXPENSIVE to replace. This is due to location, ass-end of the engine block, and the fact that it is virtually an pricey piece of digital electronic equipment and not a simple physical pump.

I prefer the fan driven pump on the fact that it will decrease service costs alone.

This was a true thing on the M engines in the E46/E39 era but the advent of the Cast Iron Metal EMP Stewart Water Pump with proper bearings (which not only diminished all future pump failure permanently but also measurably improved engine performance) showed that you can have a reliable belt driven pump in a high performance production engine for not much more money.

[G80indy]

The Stewart pump is on my e36/7 and e46, proactive upgrade!
