My new 2009 Jetta TDI

[subsonic]

There is a on off for stability control.  Going to do some research in the book.

From online:

"The electronic differential lock (EDL) employed by Volkswagen is not - as the name suggests - a differential lock at all. Sensors monitor wheel speeds, and if one is rotating substantially faster than the other (i.e. slipping) the EDL system momentarily brakes it. This effectively transfers all the power to the other wheel."

Owners manual says this will work at vehicles speeds up to 50mph.

Drove like a granny on the way home.  Got 51.4 mpg over 60 miles.  Car has a little over 200 miles on it.  I think  when everything is well seated and broken in I will be able to get higher.

Got some photo's.  Car is dusty so the real shine is a bit muted.

Nice looking car you got there

So can someone tell me, because I've been looking all over for this information and can't find it anywhere, is this new 2.0 litre clean diesel engine an interference motor and if it is, did the engineers at VW finally get it right and use a timing chain as opposed to a rubber belt (fingers crossed, hoping the answer will be what I want it to be).

Thanks to anyone who knows this.

Of course it's an interference motor. I'm pretty sure ALL diesels and most gassers these days are. And yes, it's got a belt. Belts stretch less than chains allowing more precise timing. The belt is not just "rubber". It has very strong kevlar fibres embedded in it.

hey chrissev!  haven't heard from you in a long time.  timing chains aren't really the solution...  they can still break at 250,000km's+ and like sub said, they stretch, which is not good for a precise motor.  with new advancements in materials, i would believe that timing belts will break the 160,000km mark in the near future.

and about the interference motor... i know GM has a lot of them now, because they're noticing a trend.  i used to love driving a vw gasser knowing that if the timing belt broke, i could just tow it over to a mechanic and get it replaced...  the problem is that it will usually break when you're in a hurry to get somewhere and then you're out of a car for a day or more.  just regular maintenance  :wink:

so how's the cobalt?

Hello again:  The cobalt is ok.  It's powerful enough and the gas mileage isn't terrible (about 28mpg in the city, 35 on the highway).  It's not a VW though (handling is really not very good at all, though better than most GM economy cars).  I'm thinking of trading it in for a new jetta (probably a station wagon) with the clean diesel engine, within the next two years or so (once they get all the bugs worked out of the design).  

So the timing belts in these new clean diesels will do 160,000km?  That is quite a bit better than the 60,000 km the belts in the old TDI jettas would do before needing replacement.  I think the cobalt engine may be interference, not sure.  But it has a chain.  I have noticed that GM timing chain engines gradually go out of time and it isn't possible to fix this by resetting the timing.  Probably the chain is the culprit (stretching).  At any rate these new VW clean diesels with their 140 hp and the light jetta body look too good to miss for me, I want one.  Beautiful cars.

[subsonic]

They haul! :twisted:

[jtanguay]

yea... diesel HP shouldn't be compared to gasser HP.  it's the diesel torque that makes them fun

chipped i bet you could go 200hp without any other mods, but you would probably smoke a bit...  maybe they've locked the ECU to limit particulates???

I was thinking about oil changes in this car on the drive home yesterday and about engine break in.  I have always heard that you should not break in a new engine with a synthetic due to ring seating problems.  This car comes with it from the factory :?   I wonder if this will necesitate  a longer breakin period for ring seating?  Anyone have any knowledge on this?

[Slave2School]

Sub, from what I have seen the real break in is done on an engine dyno with a computer controlling it at the factory  If it was mine I would just leave the factory fill till they tell you to change it.  There was a bit of discussion on this over at tdiclub.com

That's to dispel the myth that you are getting an hour 0 engine.  The car you buy off the showroom floor has already had it's engine tested on the engine dyno, installed and driven around the factory, on and off a truck or ship, and around the dealership.  

A friend saw a brand new Dodge viper truck come off the transport with bald tires.......and some cars like the Nissan GTR is driven hard around a test track at the factory.  If a secret engine break in technique gave extra power, why don't hand built Corvette Z06 or Ferrari engines get this treatment?  Ferrari can't add it to the cost of a $250,000 car?

Proper engine warm up and consistent maintenance are more of a long term factor than slightly different break in methods.  As long as you follow the owner's handbook, the engine will break in OK.  

In the end, almost all original owners get rid of the car before they need a new engine, especially a TDI engine due to worn rings, so does it make any difference?  Buyers guide for the 2009:

hey subsonic wanna trade for my shinney caddy?
thats a nice car you got there!
i sure you can go 5K between oil changes too!
well i can with our '04 TDI

Thats a mighty tempting offer Duane, but I'll have to pass.  I think my wife would stick a shiv in my kidney if I traded off the new car.

First thing went wrong with the car today.  Came out this morning to drive the kids to school and noticed that the sunroof was open.  It can either slide back or just have the rear tilt up.  I had placed the switch into the closed position the night before and gone in.  The sunroof has slid closed but the rear had opened up for some reason.  I played with the switch this morning and it was squirlly.  Looks like I need to bring it in to the dealer.  Have over 3000 miles on it now.
