Guessing it’s ‘illegal’ to take these GPF’s off and map out the sensors?
Sounds like a right ball ache. Guessing the car just gets worse and worse until it becomes full then it almost dies until you drive around pointlessly to get it clear.
Do all new petrol cars come with them? Seems like the dumbest thing ever and is putting me off a new car purchase since it sounds like you spend more time babying the car than enjoying it. Good for the turtles though I suppose
Will a sept 2019 registered gti+ likely have the GPF?
I think it would be considered illegal to remove the GPF. It probably also invalidates your insurance - e.g. if you’re involved in an accident and the insurance company needed to inspect the vehicle to authorise repairs and discovers it’d been removed.
Particulate filters are nothing new; diesel cars have had particulate filters for many years; two of the Golfs I owned had them and I knew when they were performing an active regen, but I never had any issues with them in nine years of ownership, other than having to have a new sensor fitted on the mk5 Golf.
I’m not sure if all new petrol cars (in the UK) have GPF’s - they’re not required in some overseas countries, so it probably depends on how stringent emissions legislation is in a particular country and how ‘clean’ an engine will run without a GPF. During normal day to day driving you won’t be aware of any build up of soot over time in the GPF and performance is not affected so no; the car doesn’t get progressively ‘worse and worse until it becomes full then it almost dies’. If you’re driving mainly longer journeys when the engine can get up to optimum operating temperature, regeneration should be mainly passive and you shouldn’t notice it. It’s if you’re driving predominantly short distances on a cold engine that you’re likely to experience forced regens. My driving is around 2/3rds longer journeys and 1/3rd journeys up to 7-8 miles long, although anything less than 3-4 miles if I don’t need to carry anything heavy then I’ll walk; better for my health and the health of the planet!

I’ve experienced maybe three GPF regens in 18 months of ownership and I can live with that. Come to think of it, the one at the end of last week may have actually been the only forced regen - with the previous two, I only really noticed a deeper exhaust note and a ‘hot’ smell - no lumpiness or hesitancy and no high fuel consumption, so the previous two were probably passive regenerations. So one forced regen in 18 months isn’t an issue with me.
A September 2019 registered GTI+ will have a GPF; their introduction coincided with the move to the WLTP test procedures for fuel consumption and emissions testing. A member on this forum had to have their GTI+ (one of the later / last non-GPF equipped cars) registered by the end of Aug 2018, which was the deadline date for registering new non-WLTP compliant vehicles, so a Sept 2019 registered GTI+ will definitely have a GPF.
Living with a car with a DPF isn’t a big deal at all IMHO - and you shouldn’t have any issues with sooty exhaust tips on a GPF-equipped car; mine stay spotlessly clean
. Owners of GPF-equipped mk7.5 Golf GTI’s over on golfgtiforum.co.uk also have very shiny exhaust tips too
