unlucky first time TDi owner

Mate forgive my ignorance and laziness but tell me more about this dpf delete....

This is all new to me, this tdi bizzo.

The latest EURO emissions spec was adopted by Australian so that from 1 Jan 2008 all diesels sold in this country needed to have a DPF (Diesel Particulate Filter).

What it does is essentially stores all the 'soot' that comes out from the motor and burns it off slowly over time as you drive so as to not release any soot sized particles into the atmosphere.

The things is is that it is a restriction to the motor. It has to force exhaust gas through about 3 90 degree bends and through tiny meshes to trap the soot.

It took people about 18 months to finally circumvent it and for about $2k you can have it replaced with a straight dump pipe and a software tune.

The first batch have just arrived in Aus but from what I know they haven't been installed on anyone's car just yet. Can't wait though!

Wow so is it a matter of a new exhaust? or deleting the rear muffler? And just adding an oettinger chip??
Now I'm really excited

Also TDI's have a Variable Vane Turbo.

Basically it electronically adjusts the vanes in the turbo to keep maximum boost pressure across the rev range. That said if you see a boost gauge on a TDI it doesn't really show that.

The only petrol car with one is the 911 Turbo. Even the polos have em in diesel. The reason being is that TDI exhaust gas temps, EGT, are considerably lower that petrol.

That and the immense amount of torque, due to the long stroke and v. high compression of diesel motors, 19.5 :1, is what makes it stand up and go in any gear.

The GT is quite different to all other TDI's in that the power doesn't fall away after 4000rpm, it holds up to 5000rpm, if you wanna redline it

Well the DPF delete comes with software to trick the car into believing that the DPF is still there but while you're at it you moswell tune it up to match the new exhaust flow.

So doing that kinds covers all bases.

Suspension will give you tons more control and traction. I have bushes, an ALK, anit lift kit, and a rear sway bar on mine and it takes out the understeer just nicely, so no more "loading up" feel of the motor wanting to go the opposite way in hard cornering.

You'd want coilovers though. A guy I know who races his R32 said to me he has bought every diff type of suspension, springs, dampners, combo kits, and coilovers and you wouldn't waste your money on anything but coilovers.

Michas GT TDI has H&R coilovers on it and it's cornering ability leaves my car behind.

Last time I looked my GT TDI redlined at 4500. Any time I've reved it that high the power dropped away sharply and there was a lot more acceleration at lower revs.

[benough]

Sorry you're right, take all the figures back 500 rpm

Hi Mate,

Where did you get your anti lift kit? my jetta 125tdi desperately needs it!

cheers

Dude they are great. When it first goes on you can feel the tyre pushing into the road more for better grip.

I think they were designed for the 2.0 Petrol motor so w/ the extra weight of the TDI they creak on small slow bumps.

Welcome new TDI owner to our happy forum

Mk5 chassis does indeed seem to perform well with coilovers, i think the mk5 is a little sloshy on stock suspension

Just for the record, I was once very confused one early early morning when I had a mad run up the old pacific hyway going south from Brooklin towards Berowra with a 350Z. This guy had a little rear end step outage around some of the corners and I could see from his tailpipes smoking every time he applied power that he was up if for the money.

I was surprised to keep up in my mk3 turbo diesel, thats for sure.

Faaark I'm just magining my car with an extra 50kw, that wld be not to mention torques

Read about the dpf's too keen to hear how they go, hurry up delivery guy!

Started a similar thread on tdiclub and got ab****e zero response, maybe the yanks are a little upset they don't get GT's.

Having said that they have some serious bizzo goin on over there with their tdi's hence me askng cog on his thread what's next heads, cam inlet etc

Yeah we are like 3 years ahead of them in terms of motors from VW but they tune the bejesus out of their older ones.

There's a guy on vortex who has a MK3 TDI that makes more torque than my car. He told me to get all these injectors, turbo, manifolds etc. Turns out I have better stuff from the factory plus 16V, haha!

[Gregski]

Yep definetly an anger jealous thing then!

Hey can anyone tell me why I'm seeing oil on my driveway? Is it e cessive blow by? I have been driving quite spiritedly of late! Any way I can rectfy? I'm 5ks away from my 90k service

[benough]

no idea dude.

Can you see any signs of leaking in the engine bay?

I doubt it would be blowby. Let's just hope it's something simple like a sump gasket.

[Greg Roles]

I'd hazzard a guess it's the blowby that pools in the bottom of the intercooler pipes dripping out of the pipe - intercooler junction.

[Gregski]

Just popped the hood and can't see shyt

just saw the engine covers are loose and all the mounting brackets have been broken as well, fkn hopeless service techs!

Oil looks quite clean, and I did top it up about a week or two ago? Might be some excess overflow?
