What gives the Passat 2 TDi 125kw v the Golfs 103Kw

[Spoddy]

Are the differences in the engine, the turbo , the chip or all of them?

I believe its just remapping changes in the ECU....................

but the GT Sport does come with a Particulate Filter IIRC.

same engine and i think same turbo. the 125 is just basically a "chipped" 103. the golf gt sport diesel comes as a 125kw so both the engines are available on both cars.

Therefore a re-chpping of the 103 to the 125 should not void any warranties

haha wouldn't that be the perfect world... sadly it does void the warranty but i guess what it means is that its fairly safe to rechip it. and since the engine is a few years old now, you should be sweet

Specs are very similar but where does the change in compression ration come from? 103kw 18:1, 125kw 18.5:1
Bore and stroke are the same? Could it be a different cylinder head?

hmm strange. dont know anymore than what i've said already

[brackie]

Perhaps they use a thinner head gasket

I'm told (unverified) that VW does approve one flash for the TDI. I won't mention names as it's too emotive a subject, but do your homework and it may pay dividends.

I'm totally happy with the performance of my TDI. As I've said many times before, with diesels it's how you drive them that counts

Hi Brackie,
Will VW sell an upgrade/flash as an after sale upgrade? If so I couldn't imagine they would void any warranty.

I was under the impression that the 125KW version will be in the MY08 model.

FWIW my 103KW version was spotted doing 5555km yesterday, been happy so far with it, now time for the ehancements to begin!
