Just got the VIN through for my 335i today and put it into BMWVin.com to check the spec. One of the items that came up was this:

S4NEA BLOW-BY-HEIZER Blow-by heater

Anyone know what that is?

Option 4NE. Here is a description I copied.

It is a small convienience for those of us in a cold climate where we will be out of the car for a short amount of time but want to keep the car warmer while we are gone.

I noticed the same thing on my order and found the same post that E34 quoted. But F30 doesn't have the REST function, right (at least in the US)? Do other markets get it?

I have only seen the 4NE option listed on the Canadian F30 335i, where it is a standard feature. Not an option on the 328i here in Canada though.

It's on my purchase order for ED as well. US F30 335.

When do they release the vin? A week or two before final production? I'm doing Ed mid sep. Just curious.

In my case I got the VIN 4 days ago. Car is actually at the dealers today but I'm not collecting it until 1st Sep.

I think you are correct.

Here S4NEA is mentioned with vent hose

http://parts.bmwofsouthatlanta.com/p...127584128.html


that same vent hose part number shows up on the F30 on Real Oem

I'm not saying you're wrong, but if that's the case then it seems a bit odd that it's in the list of options on BMWVin.com? Surely that would would be a standard part of the engine?

From another forum thanks to Powderguy:

"...just found out what the Blow By Heater option ,04NE, really is. This is a addition to the N55 motor in which excess "blow-by-heat" is funneled to an air tube that may tend to freeze up in colder climates. Not the Heat at Rest I wanted."

The part shown on Real OEM looks just like the part described by MMMMM... and at the DBK website. here is the translated link:

The part number is 11127584128; although it is not listed as 4NE on the F30 section of Real OEM if you search the part # you will see it listed on many other vehicles and described as:

"Vent hose
For vehicles with
Blow-by heater = Yes (S4NEA = Yes)"

It is maybe listed as an option because it is only for specific climates...colder ones.

Maybe some Florida, or other hot temp US states, owners could chime in and let us know if they also have S4NEA aka 4NE Blow By Heater option?

The part #11127584128 is specific to the *35 engines and although it is not listed as 4NE on the F30 section of Real OEM if you search the part # you will see it listed on many other *35 engine vehicles and described as:

"Vent hose
For vehicles with
Blow-by heater = Yes (S4NEA = Yes)"

Hmm, I'm in FL and I got this option. Hope it doesn't affect thermal performance. Maybe faster warm ups?

Just noticed that this is on my build sheet for MY2014 F31 328i xDrive. Canada.
