I've never actually seen the filter element of an automotive diesel fuel filter before. All my other rides had spin-on filters. So I don't have a lot of experience here to draw on. Like I say, it was dirty but not cr@ppy. I try to stick with good fuel from good stations, so 'dirty but not cr@ppy' would be about what I would expect after 8K miles.

At first I was a little bewildered that VW doesn't use a spin-on filter, but now I really like the idea of being able to put an eyeball on the filter element during a change. You can never be too rich or have too much information about what's going on under your hood.

Just added a FAQ #16, prompted by a PM from a new member: "how do I remove the plastic cowl from the engine?" That prompted me to recall that we've seen this question several times. In fact, I think I was the first newbie to ask it! My understanding is that the '09 (with its snap fittings) differs from previous TDIs in this regard(?), in which case its legitimately an '09-specific issue.

*shrugs* My 06 R&R the same way. After a while they things they snap in will wear some and it will remove a lot easier.

Being that I want to keep my high pressure pump, rail, and injectors as clean and particle free as possible, I also run an aux. 2 micron filter after the 7 micron stock one.

I hope that VW takes filtering on a high pressure common rail system seriously. Small particles 5-10microns in size can cause serious damage when fired at 20-29,000psi through modern injectors over time. I also don't want to leave the fate of my engine in the hands of the fuel distributors and gas stations, with their sometimes sub-par filtering. It is the same problem experienced in any high pressure hydraulic system.

Does anyone know about the new fuel filters on this new engine?

Thanks,

Chris
A lot of the cummins had a "pull" style electric fuel pump in the engine bay. It would start to get weak or fail altogether and the injector pump would have the sole job of transferring fuel. Many times you couldn't tell until it was too late and your injector pump died.

Dodge supplied a revised kit to put the transfer pump close to the tank as it was more effective and lasted longer as a "push" pump. Unfortunately many transfer and injector pumps were lost this way.

Default New '09 Jetta TDI Questions

Greetings!

I am the proud new owner of an '09 Jetta TDI for about two weeks now. I've been lurking around soaking up all this great info about my new car and following DBW's break in procedure. At this point (1200 miles on the car) I have a few questions:

1. What exactly does the turbo sound like? I have no doubt that it is working, as the car has plenty of get up and go . I hear folks talking about a whining sound, like I hear with my uncle's F-250 turbo-diesel. It's very audible and unmistakable. I hear no such sound from my Jetta TDI. There is a slight sound of something turning on ball bearings or something (like spinning the wheels on a skateboard or something) when accelerating, but I have to really listen for it. Maybe I just don't know what to listen for.

2. What's with the daytime running lights? Are they supposed to be the low beam headlights? The low beams come on automatically when I crank up the motor, then when I turn on the head light switch, a set of dim lights in the same pod as the hi-beams at the 2 O'clock (passenger side) and 10 O'clock (driver side) come on. Seems to me it should be the other way around.

Sorry if these questions seem kinda dumb. Just never owned a car with turbo or DRLs.

Ken

Your DRL's are working how VW intended them to. Different car manufactures use different setups for DRL's

Great FAQ, answered some of my main concerns

I'm surprised to read the part about the max bio-diesel rating, the lowest mixture I have seen around my area is B15 and even the dealership I bought the car from filled it up at a B15 gas station.
Do you think this might be high enough to effect my warranty?

Yea, the DRLs are just the low beam headlights, but they are running at something like 80% normal power. You probably can't notice the decrease in brightness with your eyes, but the power reduction will increase the life of the bulb. The little tiny bulbs in the reflector of the high beam are your 'city lights', also known as parking lights or position indicators. If you get a Euroswitch and disable the DRLs in the computer, it becomes possible to turn on just the parking lights. The parking lights also stay on if you turn off the car with the headlights switched on.

Thanks guys for the replies. I think I'm beginning to see the light.

MBoni, I noticed you have OEM fog lights on your JSW. As far as I know, they are not offered with the Jetta Sedan. Any reason that you know of that they can't be retrofitted to the sedan? Are the two not the same vehicle in the front half? Would love to have a set!

FYI, I've just updated the FAQ to:

a) correct my previous lack of deep understanding about fuel heating (Q5)
b) add a Q17 regarding The Silence Of The Turbo

A: What's that you say? I couldn't hear you over the awesome scream of my turbo. No, actually, most of us can't hear our '09 turbos; they're scary-quiet...and those of us with long turbodiesel experience in other vehicles kinda miss it. But it's one heckuva turbo anyways (puts out 22 PSI, stock), and it sure gets the job done. Think of it as the strong, silent type.
Thanks Doc, works for me!
