Which Type of Tyre Pressure Monitoring System?

[Skinnee D]

So as earlier stated, around 25%.

I'd like to think one would be able to feel a 25% pressure loss without a warning light, especially at the front.
It might be pulling to one side don't you think?

Mine was a rear tyre and wasn't felt before it alarmed, though it was on the motorway. As you say, maybe noticeable driving if on the front.

Annoyingly I seem to have a slow puncture....takes a couple of weeks to loose about 10 psi, light comes on at about 25% loss. And it does tell me which wheel when I turn on the ignition, the time after the light has come on.

And front left tyre, and I didn't notice it, though I drive sensibly

Why don't you get it repaired? Or is that a silly question?

Very sensible, ....just doing a bit of research....there is no visible puncture.....and no air coming out of the valve
I was just trying a new valve core ........but that didnt work
So I need to take it in.

My T6 Ocean pick up a 4psi pressure loss, just under 10%, it takes about 10 miles at 70mph to calculate and fire the alarm. The van runs on Dunlops at 45psi.

I have the wheel based pressure sensors on my VW Passat and it's an absolute doodle chnaging over to winter tyres. I don't have any sensors on the winter rims and tyres and the system automatically switches the system off when it fails to detect the sensors. There is no further warning lights that comes up at all. When I switch back to the summer alloys with the sensors the system just reboots back up after a few hundred meters.

I have to say The system is pretty good but not really that necessary. You can tell a low tyre pressure within a few meters of driving or the first corner.

Hi. I'm in a bit of bother!
Looking into tyre pressures re. abs pump and traction warning light??
I recently replaced both rear tyres, immediately the traction control light came on and has remained on since. I mentioned it at the tyre shop but they weren't able to scan the vehicle.
Next went to local vw specialist, not main dealer, who ran a scan and reported that the abs pump shows an internal fault error code. I had it removed and sent to ECU testing (found here) who were unable to find a fault. It's now back in vehicle and warning light still on.
Today I have checked tyre pressures and put some air in both fronts.
My question is could the tyre change & slightly low front tyres be picked up by the abs system and cause warning light to come on? And if so should I be able to get the error reset?
Any thoughts/advice most welcome
Thanks

I've seen numerous cases where the rear ABS wiring goes faulty causing problems.
Check all the way from hub to body.
It may be related to jacking up for tyre change.

Have you reset the tyre pressure monitor. You have to do it each time you fiddle with the tyres.

Thanks, I don't think there's TPMS on a 06 Cali.

The ABS sensors are the most common cause of a Traction Control error, those or the wiring, particularly on the rear. Followed by the ABS control unit failing, but rarely.
A generic rather than VW diagnostic computer may not accurately read the fault.
ABS sensors are not difficult or expensive to replace.

I've seen a thread before about rear sensor wiring being prone to problems. Memory not good but seem to recollect that the most likely place for damage is under the rear wheel arch.
Maybe VCDS will show up which one is faulty.
Perhaps info here...

Thanks for the replies. Van booked in Tuesday week so will get sorted.
