Golf R Observations and Questions

iirc the sensors don't measure pressure but the rolling circumference from the ABS. I could enable the function on my car as well despite not having the reset button, just means I'd always have to use VCDS to reset it.

Correct

Most use this cheaper method

Never had a problem in the GTI

Oh well, it is a VW

yes, and they monitor by detecting a discrepancy of the rotational speed of the wheels on the same side of the car. hence, heavy cornering with a bit of sideways action in the GTI sets them off.. hard bumps do also.

Sounds like it's too finely tuned setup. Too instant in any changes occurring although I can see the benefits of this I guess.

Yeah, I was almost going to ask if he'd hit any massive potholes but highly doubted it

i think I read somewhere a 25% pressure change in any one tyre was required to set the system off...

That's alot isn't it. That equates to 10psi in my case.

Entice has it spot on.....difference in rim speed sets it off as a 'please check'. It's in the manual that the TPMS has '3 settings'

I was on the F3 last year.....3 adults, 1 kid and dog with the boot full (and heavy) thanks to long Easter weekend.....TPMS went off.....

My wife decided to RTFM after a visual check by me....explained it well.

Well I have been spoilt the last few days. Got to drive the R along the Great Ocean Road in Vic a few times, taking the kids down to stay with some friends in Lorne. So after dropping them off the drive home on a weeknight around 9pm was alot of fun. Was able to give it a squirt on the run back through the windy corners without going too overboard, esp near any blind corners or with other cars nearby.

Anyway not having a much of a reference point (other than my old Skyline R32 GTS-t), I have to say the R felt quite nimble and planted to the road when the DSG and ACC are in sport mode. I love the tight direct steering feel you get when the ACC is in sport mode. Also of note the brakes are much better than any other cars I have owned. Being able to brake so much later coming into corners and feel confident about it was a great feeling. Yeah I know its no GTR or Evo performance but still the R does a very solid job all round, in comfort too and felt great on a road like that.

Can only imagine how much fun a Nissan R35 GTR would be down the GOR tho. One of the great drives of the world
