Any N55 HPFP failures yet?

Or any other major problems? There were reports of several HPFP failures with the N54 as early as 1-2K miles. I have a 2011 135i DCT with 2200 miles on it (early May pick up) and am keeping my fingers crossed. I came from a 335i 6MT and so far am very impressed. Not crazy about the paddle shifters moving with the wheel or that it will downshift for you even in M mode if it thinks that your not doing it right. Otherwise no complaints.

I had a couple 2-3 second cranks when the car was still in break in stage. That made me a bit nervous, but now at 2600 miles, it starts right up as soon as I touch the button, every time.

It will only downshift in M mode if you go under 1k RPM so you don't stall, nothing wrong with that. You won't be getting that low in rpm unless you're in traffic anyway.

I've driven a manual tranny the last ten years and have never stalled, so I know how to shift. It consistently seems to downshift before I get a chance to when pulling up to a stop sign or red light. Sure it's not a problem. but it takes some of the "manual" feel out of the DCT. Also I hear it upshifts when you red line though I've not yet pushed it that hard to find out.

I'll agree with you there, when I have it in Manual mode in traffic now, I tend to just let it downshift on it's own.

Also, it does upshift at redline, but I don't see that as a problem either, bouncing off the rev limiter isn't exactly good for the engine nor is there really any benefit to it. Takes away from the 6MT feeling, but this isn't a 6MT.

Automatics are known to do that from time to time.

To respond to the OP's question, I picked up my 2011 6MT on April 21, and 3 months later it now has over 12,000 km (7500 miles!!)

Aside from two isolated sound system/speaker anomalies that each occurred only once, the car has not missed a beat. The N55 has started immediately every single time I pushed the button since the day I took delivery. I love this car! We are indeed a fortunate bunch.

7,000 miles! I thought the 4,700 on mine was a lot! No issues so far for me either!

So exactly how do you define an automatic? (better do your reading before responding)

I define an auto "automatic" trans as a trans which uses a torque converter to couple engine power to the trans, and then the shifts are done without further need for driver input, once the forward "drive" is selected.

An "auto-manual" is, again, a torque converter transmission that can take driver input as to which gear the trans will automatically switch to.

An dual-clutch, SMG, DCT, DSG, ect...is a clutch coupled trans in which the clutch engage/disengage is operated automatically, with the ability to change gears automatically as well. Also, it has the ability for the driver to select which gear the trans will automatically engage when driver input is given.

So, basically, it comes down to how the engine power is coupled to the trans. A "true" automatic trans has a torque converter.
The feel of the shift is different between a TC automatic and a true clutched trans that can operate automatically.
A TC can pull off softer and smoother shifts as it has a soft coupling (fluid), whereas a clutched "auto" trans retains the more direct, and harder, shift of a true manual.
They each have their own appealing qualities.

BTW, given the title of this thread, where are all those failed N55 HPFP's?

I would think a thread title like this would at least get 1, no?

This.

If your left leg is not moving, you're driving some form of an automatic.

.

By very definition "automatic" means it shifts by itself. Throwing the torque converter in there is pointless. Do you not consider a CVT an automatic? All torque converter based transmission can take driver input for gear selection. Calling them manuals because of that is just marketing BS.

DCT is an automatic transmission. It shifts automatically. That doesn't means it's the same as a traditional torque converter based transmission, but it's damn sure not manual in any sense of the word.

That's why I shake my left leg around quite a bit when I'm paddle shifting and leaving that "real manual" 135i guy in the dust.

That's not exactly true either. Sequential manual race boxes with straight cut gears are manuals, but you don't use the clutch.

For example:




Of course, you're not likely to see that in a typical street car.

I am going to start off saying I agree 100% but here's my question.

If the manual mode lets user select gear no matter what. (won't upshift or downshift) Does that constitute as a manual? Does manual must include a clutch or simply implies user selection of gears.


I guess you just answered that question above
