SNOW.

I have a good set of snow tires, but I got stuck 3x today! Not interested in Xdrive.

Front-drivera just don't get stuck that worse.

Using DTC?

-N

[visor]

It is standard....



....on the M3!

+1 for DTC.

< BTW, I agree completely... see my avatar signature!

DTC doesn't cut it.

"Traction Aid" are my friend. Used them twice today.



Should have bought those studded tires.

[albeik]

my S2000 has no traction control, but with LSD and winter tires had no problems today... SUVs/Trucks kept looking at me funny today.. :P

[Quasimodem]

I think the 335d must use LSD. Besides it creates less polution.

[SG333E]

Funny, I was just noticing this. The performance side of me wishes the car had LSD, but let's face it 99.x% of the time you don't need it. The practical side of me in winter notices the lack of LSD at every stop in snow/ice, even with winter tires as mentioned. That is a sore spot.

[mapezzul]

From 3/08 and on all 3 Series in the US have the E-diff, which is about 90% as effective as a true LSD. The 1 series had this from launch. BMW will not include an LSD in any non-///M cars for weight and cost reasons. HOWEVER- that being said the 7 and Z4 will have the new rear diff that puts power to the outside wheels like in the X6; Not sure if it locks, or sends equal power in a rear drive application, though I will ask.

With snow tires and the E-diff the car will get through most snow.

To activate the e-Diff hold the DSC for 3 seconds and all nannies turn off but the e-diff remains active as it is NOT a nanny so there is no engine cutting or yaw controlled braking.

It will apply the brakes gradually to the spinning wheel to help balance power distribution. And yes it will allow you to leave equal "strips" when peeling out.

so if my car is made in may 08, it will have it? nice nice

Rear-drivera gets more worse stuck than front-drivera. All-wheel-drivera gets stuck that better.

wait, i thought Xs came with LSDs?

The 335d puts out far more soot particulates and NOx than the gasoline version. Besides, diesel emissions give you cancer http://www.sfgate.com/cgi-bin/articl.../BA1PVMN0O.DTL.

So does breathing in general.

So if you don't buy a 335d and stop breathing, you lessen your chances of dying from cancer significantly.

I don't claim to be an expert, but is this true? I thought that when you held the DSC for 3 seconds it turns everything off. Whenever I do that, I just spin one tire for days. Am I wrong?

Not if your car is built after 3/08. The E-diff is always active. Like I said though, all the other safety devices and "nannies" are turn off so drive careful!

Your statements about the 335d are incorrect. The BMW Advanced Diesels have less NOx and basically zero particulate. Your information is extremely dated.

The new diesels are cleaner than the gas versions. Plain and simple.

People need to wake up and realize that these are not old school diesels.

Also note:
CO2 decreased by over 20% compared to equivalent gas powered car.
Diesel Exhaust Fluid (DEF), rather than AdBlue name.

Might want to express some interest in XI.

Don't let the diesel boys from the UK forum see this, they will have a cow.

wth is up w/ that random spoiler post?!

From the OT forums....get some BLIZZAKS

But increase your chances of dying from asphyxiation dramatically.

Geeze, thanks Michael! Were you able to get some confirmation of that?

I have been trying to figure this out for months. I test drove some 2006/7 models, and the wheelspin sucked (to be blunt). I was tempted to by a Caddilac CTS because that car had an LSD, and BMW didn't. To me that was a HUGE issue!

I was shocked shitless (tickeled pink?) when I actually took delivery of my car, and found it drove just like a car with a visocus LSD (huge difference from the 2006/2007 cars). I could not believe my luck! The e-diff on my 2008 3 series workes great (even when DSC, DTC are turned off). That was the best surprise possible!!! Yeah, it isn't as tight as a Torsen and may not be my ideal diff for the track, but it works wonderfully on the street.

A few months ago I noticed that BMW changed the owner's manual to include wording on the e-diff (this wording is not in 2006, 2007 models, but is in 2008 and 2009 3series and 1 series manuals):

"Press the {DTC} button for at least 3 seconds…
Stabilizing and drive-output promoting actions are no longer executed.

328i, 335i: in the same way as with a differential interlock, even if DSC is deactivated, brake actions are still performed on the rear axle to enhance drive output if the drive wheels experience a significant loss of traction."

(yes, it does work with the nannies all turned off - it does basically state the x-drive models don't have this feature. It also implies that the active differential is used in DTC mode, which seems to be the case from my testing.)

I've been having a ball with it, in the dry, rain, dirt, snow - it really puts the power down. I love it!!!

Chaz:

I just received official official confirmation last week. The DSC module was tweaked in 3/08 to offer the same system as the 1er released with. I have had a story drafted since last week on it but keep forgetting....

I will try to finish it up tonight along with 8 other things I am working on! hopefully if the snow holds out long enough we will have a 335d review up by Monday!

If you have any questions guys please let me know and I will try my best to answer them here and elsewhere! Just trying to help out!
