Chip

[comfortline]

How does Volkswagen get 125kW of power at 4200rpm and 350Nm of torque from the new Golf 2.0 TDI GT Sport ???

Are they using chipping (or re-mapping) technology to do this ???
I'm sure it's the same engine that's in the standard 103kW 2.0 TDI Golf.

Also, I read some where that Volkswagen Australia is currently considering maintaining full new car warranty with the Oettinger upgrade.

Does anyone know if that was ever approved ????

The GT motor has different injectors (piezo's) and 18.5 compression (up half a point). There are other differences too.

Most common chips will bring you up to this level anyway.

do you mean different injectors or a different fuel delivery system? don't piezzo injectors run off commonrail?

the gt also has a DPF! suckers! delete!!

Having recently spent some time on erwin, and having just read the 125kw self study manual, the differences are according to VW themselves:

Different injectors and higher pressure
Bigger turbo, different actuator mechanism and more accurate sensor
Lightened but forged crank - 4 counterweights instead of 8
Extra cooling channels in the block, especially around the injectors
Different EGR, with much larger exhaust gas cooler
Different head, lower profile valves, different pistons, trick headgasket
Changes to the inlet manifold, more agressive dual port inlet design with active swirl flaps

So definately a lot more than a re-map!

copy that and paste it every time someone says "i can just chip my comfotline and it'll be the same as a gt sport" bla bla bla

Power and torque wise, it possibly will be.

But the changes VW made aid the responsiveness, just consider the crank design, lightened and less counterweighted, yet forged for strength. Would make for a revvier diesel, as much as there are revvy diesels....

Most importantly, VW considered the long term survival of the engine. Just the exhaust gas recycling cooler alone is massively different between the two vehicles, the normal TDI has a very basic cooler, and the GT has a full on liquid cooled active bypass tube design about twice the size. Just that alone is designed to cope with higher exhaust temps, so a remapped 103kw will quite possibly be overloading systems such as this.

I was amazed just how much difference there is between the two when I read both self study articles. It was pretty much a redesign from the block up.

very interesting, and good to know.

i still think that you comfortline can be chipped and driven hard without too much worry though, just as long as your prepared to make other changes like a large intercooler and completely new exhaust system optimised for low EGT's.... but i suppose, for the extra money, you would've bought a GT instead... hehe.

one day when mk5 golfs are old, THEN people can argue the benefits of buying a comfortline spec over the GT - it'll be like the GTI vs golf LS - buy the LS and mod the crap out of it, or buy the GTI and leave it stock

2.0 tdi 103kw, comfortline, dsg, it is an 08 model, that's what it was, now wow no acceleration lag from stop and turbo thrust.

I got the same Car kertech, with the Bluefin ecu flash - it goes like a dog shot in the A** - Runs so smooth from lowdown to up high - I can highly recommend Bluefin. Great support also

Love the expression. "Goes like a dog shot in the arse.)
