No experience in the type R but my golf sportwagon had a similar system (at least I assume it was, they all must be calculating this in a similar way). I had a flat tire on the highway, hit a pothole really hard and took a while for the system to tell me.

It depends on how slow or fast the air leak is.
Any time you adjust tire pressure (assuming you’d let a little air out before tracking) be sure to recalibrate the TPMS. This will help ensure the system works properly.

I have never, ever, had the car that said I have a low pressure and its actually low....so I don't believe this system does anything useful at all...
And its not just this car, FK8 and also my MK7 GTI before that. All had the ABS wheel speed based TPMS...
Its a system there to let OEM meet NHTSA requirement of having a "TPMS" without adding cost of having sensors. To us though its also a benefit for not needing to have sensors for all the wheels. Just don't rely on it to tell you when you have low pressure.

I had a small leak once on my tires and the cars TPMS sensor worked well for me..
I would air the tire back up and re-set the TPMS on the dash and every time it would come back on, the tire pressure was indeed low.
However, i also once had a severe puncture on the road, and by the time the TPMS light came on, the tire was already flat.
Seems to be that for any rapid loss of air, the cars TPMS system is too slow.
For some slow leaking, it works well.

Indirect TPMS is not very responsive. When a rock punctured a tire a year and a half ago, TPMS has not detected a low tire after driving for a mile.

I hit a massive pothole early this year, leaving two giant gashes in my sidewall. The car immediately started pulling to the left, and I was able to safely limp into my garage and get a tow. At no point did the car's TPMS system ever go off. Completely useless, in my opinion.
