WLTP Golf GTI Performance petrol particulate filter query

[wantmygti]

From what I was told at Progressive Parts, my 2018 Performance which I got in June has the the petrol particulate filter. You can see it in this picture.

Wow that's quite a large unit, I was expecting a small filter like my wife's DPF which is tiny.
Thanks for posting the pictures

I’m assuming the big unit is a silencer and the filter is the smaller unit towards the bottom of the photo?

I belive the search for the missing dsg fart endeth here! 

Good shout. And suggests all 7.5’s are running the filter.

I believe the filter is the small cylinder shaped item towards the front.

I'd assume the same - closest unit to the manifold, for quicker heat-up.

Easy way to tell if you have a GPF on your GTI or R - if your exhaust tips soot up then you don't have a GPF. If you're not producing soot then tbe GPF is in place and working - GTDs have clean tips because the DPF is eradicating the soot that would otherwise deposit on the exhaust tips.

Yes, smaller cylindrical box is the particulate filter. The large resonater is now sat in my garage...

The UP! GTI has been running a GPF from launch (although strangely, 115ps 1.0TSI engined variants of other models didn't - but probably do now since Summer shutdown). My May build Polo GTI+ certainly doesn't have one.

Petrol engines don't run hotter than diesel engines (diesel combusting at 700C under pressure induced autoignition  Petrol ignited at about 400C by spark ).

The petrol engine being much less efficient kicks out a lot more heat to the exhaust as less kinetic energy is produced. So the exhaust warms up quicker  which is what you need for particulate filter regeneration and burning off those particulates. Petrol particulates are smaller/finer than diesel ones, so are also easier to burn off.

There should be very few people getting GPFs clogging up in use, unless they literally have a 2 mile commute.


Thanks for the clarification re engine running temperatures vs exhaust temp.......learn something new every day😀

Oh wow thanks for correcting me on that one........I thought the big one was the filter (been a long day!) . Good to see the filter is the small one nearer the engine for regenerations.

I take it your GTI sounds very nice now 😀

Hmm...my May 2018 GTI (non performance model), has always had totally soot free tailpipes (spotless each week, just like my previous GTD’s - except for road tar), but I’m pretty sure mine won’t have a GPF ?

Not a Golf GTI, but my 2016 previous generation Polo GTI has also always had soot free tailpipes in the nearly three years I’ve owned it from new, and it definitely doesn’t have s GPF.

I’m guessing it might have one. My 2017 7.5 230 model sooted up both tailpipes really badly after a weeks worth of driving, something I noticed my 2018 7.5 Performance doesn’t do.
