Even the active with live pressure levels takes a few seconds of movement, well at least the version I had on the last car, a VW Tiguan, did. The sensors in the wheel go to sleep when not moving to save battery. They kicked in after around 100m unless it was very cold

Why is it so hard to believe? The system is based on the ABS sensors if the car is not moving they won’t be doing anything to be able to see a difference

I am debating whether to fit an after market system as there are a few that have a phone app and work via CarPlay. Only issue is the hassle and cost of getting the sensors installed. I’m not keen on the large valve cap style as they’d put strain on the rubber valves, so would need to be tyres off and metal valves and internal sensors fitted for me.

You would need to go for another drive as the passive state will only alert when moving

Weird. Definitely told me which wheel, both times it alerted. I’ve kept it topped up every couple of weeks since. I was also surprised that it alerted at such a low differential. My 2017 Q3 had to be around 10 psi low and the 2011 TT was flatter than a !Removed! and never alerted!

It pops up, with a very loud beep, in the centre of the driver display (the one behind the steering wheel, not the centre of the dash) It is in yellow text. Can’t remember the exact text, but is something like “Low pressure rear near side tyre”

Just to be clear, I don’t have active TPMS that show the live pressure readings, I have passive but it does tell me which specific wheel is low. I think the SQ6 has active as was parked next to one and it has metal valve stems, the tell tale sign

Mine is also the Quattro. Don’t believe the distance/consumption. Like all cars, including ICE it is based on impossible conditions that the car will never achieve over a sustained period in real life. I think I could possibly get around 330 of real driving in the middle of summer, about 220 in winter. The latter I know as it is a May 25 build that I’ve had since September so have done the autumn & winter but have seen a positive increase so far in May, so guesstimating the summer distance. Hills also have a big influence. 8 miles to work this morning 5.7 miles/kWh. Home tonight 2.1. Guess which is mostly downhill!! Did once manage over 20 m/kWh for the first 3 miles. It was 6am so no traffic and I get every green light 😁

I’m not sure where you are based or what spec you have. I have a 2025 UK S-line and get told which wheel has the low pressure. The system is fairly consistent and alerts at a 2 psi variation ( I have a slow leak of around 0.5 psi/week on the rear passenger side but can’t find any nail/screw. Must get it looked at !)

The Q6 (and most Audi) use passive TPMS based on the ABS and rolling resistance (also known as the cheap 💩version). You can’t see the actual pressures. Problem is that it can trigger due to differential wear on a tyre or just because it feels like it. Had a warning a couple of months ago for a low pressure on the rear near side wheel. It was at 38 others were at 40. Had just come off the motorway. So basically, if it goes off, you need to stop and check it, or at least slow down to 50 mph if you have the standard run flats fitted

The range shown on the dash is a guestimate based on how you last drove the car, the temperature and remaining battery charge. I only ever work from the %age charge and the average consumption on the journey I’m on. To be honest, my previous ICE wasn’t a lot more accurate. I charged mine to 90% on Friday night, and it showed a range of 180 miles as Friday had been a couple of short journeys around town in traffic. Drove 154 miles, mostly motorway at 70 ish mph and still had 33% charge left on Saturday night. Temp was around 5-7 degrees. Would have a safe 70 miles left, and a nervous 80 or so. in summer I think I should get close to 300 miles range.

Over on another Q6 forum that I’m on a couple of the SQ6 owners complaining that the passenger screen gees too hot to touch
