apparently not sadly - the guy is stumped. Says it needs to go into the dealer - which isn’t open lol
1.5 TSI is a petrol engine
No DPF in sight

Ford had an issue with theirs on the Focus? I think last year? Lots of issues with warning lights regarding GPF filter, think it was a software error though and didn't seem to cause issues like the OPs.
not sure about ford but early 2019 kias with the 1.6l engine had the same and was fixed with a software update
So I turned off the radar system, the drivers warning system and all other aids (road sign recognition, blind spot monitoring etc) and then drove for 10 mins or so.
the problem went.
I then turned it all back on again and it’s still ok.
thank god - I think it may have been an issue with the front mounted radar providing highly intermittent and false readings thus constantly trying to slow the car. Who knows. The VW technician did say there had been some sparsely reported errors reported by the ECU on that front although he said it had been ok for weeks since the last error report and that it seemed ok now.....

GPF's do not have the same issues as DPF's because a petrol engine issues 30 times less particulates than a diesel plus a petrol engine runs far hotter than a diesel. A regeneration of a GPF takes place under deceleration but if the conditions are such this cannot take place the engine is forced to run lean, unlike in a DPF where fuel is pumped into the diesel engine. The ford issue is more than likely no more than either poor calibration of, or a faulty, sensor and particular, apologies for the pun, as our GPF equipped only driven around town hasn't experienced this with the same 1.0l engine, which appears to be the only one affected. Of course Ford may have changed the design of the DPF in the focus from the fiesta. EDIT: Looks like Ford have released a PCM software update for this issue..
Did you ever get this sorted? @fastwunz
Got a 1.5 DSG
Had the engine update about two weeks ago, after some diagnostics at the main dealer, it’s still happening.
Wish I realised and rejected it as soon as it arrived. Didn’t notice it too much, and was on a new car high after not having one for a while.
Put it initially down to maybe not being driven for a while.
Under warranty with independent dealer I got it from who are covering costs of any diagnostics.
Had it about a month, contacted about rejecting it awaiting response.
Just a ball ache as like the car, but that engine issue and eye brow raising poor fuel economy has ruined it for me
Unsure what it could be seems common though from googling which is annoying.

A number of software updates eventually fixed this issue.
However the infotainment system regularly doesn’t load up at all - it literally does nothing and renders the system completely useless.
However. Many MANY more problems sprung up since this thread.
The car has required:
1. An entirely new radar system including all new cameras and sensors
2. An entirely new engine management system including the physical board and module within the glovebox which is programmed specifically per vehicle - waiting for a new one of these was certainly fun….
3. An entirely new infotainment system including the screen and associated gubbins
4. An entirely new SOS module in the roof including panel and communication module
5. An entirely new gearbox after VW found metal lying inside the box whilst it slowly chewed itself to metallic death
6. Brand new disc brakes all around (the fronts were faulty)
7. Replacement speakers due to blow outs (this is a fault - the standard speakers are crud)
Circa £15k of warranty work.
The car was only on around 22k when all this was being done.
The lease company have agreed to let me hand it back early and my company are allowing me to order a new company car.
Suffice to say, I have just ordered a fully loaded BMW 330e Msport Touring in Brooklyn Grey, the upgraded 19” alloys in black, the pro pack, comfort pack and a pano roof.
I will never, ever, voluntarily drive a VW or associated manufacturer product again. Over priced, cheap interiors and awful tech issues.
My brother had similar issues with a brand new, top spec, Golf - one issue he had was the AC system randomly having a mind of its own and adjusting the temperature continuously either up or down until it got to the extreme end of the range - thousands in warranty fixes and way too much bother taking the car back and forth from VW.
One of the reasons I've been a bit leery going for a newer Tiguan and considering options at the moment.

Amen to that. Every VW I've been in in the last couple of years has been extremely disappointing from a quality point of view.
Also a colleague of mine has had loads of really quite dangerous issues with the tech in his. Reading phantom speed limit signs on the back of trucks and braking down to said limit while on the motorway. Randomly deciding it is driving on the right and braking mid overtake on the motorway because it thinks it is undertaking, that sort of stuff.
Oh yes - my car has many times emergency braked on my behalf with no danger in sight.
The radar cruise is a joke on the motorway too - it sees cars when there are none and can’t be relied upon at all to keep up with traffic.
When it works it’s quite good but sadly you loose faith with it which ultimately breads a fear of it and a complete reluctance to use it.
