Tyre pressures and tyre pressure warning light

**Foxtrot Oscar** · 23-07-2009,02:01 PM

Hi all

Forgive the stupid questions, I am at work and unable to do anything about it until I finish, but there are some questions I have that will help me deal with the issue later.

Driving back to work after lunch today, the low tyre pressure warning light came on. I didn't have time to check pressures before I had to be back in work but my questions are:

- what PSi should the tyres be inflated to (GT on 17" [Bridgestone Potentzas])
- how does the warning light work i.e. does it go on pressure, wheel speed, etc.?
- once I've checked the tyres and reinflated do I need to do anything like re-setting the sensors as per the MkV and if so, how is this done?

Blimmin hope I haven't already got a puncture in my brand new tyres!!

Many thanks.

It should say what pressures you need on the inside of the fuel flap.

Mine says 2.3 bar (33psi) all round for 2 occupants, but that is for 18" wheels on GT TSI.

Don't know about the other queries.

There are also some general questions that obviously won't be in the manual such as how the sensors actually work

.

Chris, thanks.

Once the tyres are at the pressure you want there should be a setting on the menu.
The sensors register a drop in the set pressure giving you a warning.

I checked the tyre pressures and they're 2.3 bar / 33.5 PSI all the way round, which is correct, so it seems that the sensor has triggered a false alarm.

Only thing is, the manual describes a button in front of the gearstick that allows the set / reset of the sensor system, only...I don't actally have that button, only the ESP!! So how the hell do I reset it I wonder?? Is my GT missing a button that should be there? There is nothing related to tyre pressure in the highline menu in my car.

Hmmmm. Perhaps you haven't got what you thought you are supposed to have had, then?

Check glove box!

It's funny you should say that...

I went in to the dealer today to buy some blanks for the switch row in front of the gear lever, and according to them (and they looked up my car on their database) I'm supposed to have a reset switch there, as well, only I haven't!

Not sure what's going on there!

^ Listen to this man!! Thanks David (again).

Is indeed in glovebox, see my main thread questioning it https://www.vwaudiforum.co.uk/forum/s...ad.php?t=75440.

No mention of this in the manual so kite's suggestion of 'Rtfm' was even more useless than it first appeared

.

Have now held the switch and the warning light has gone. How long for I don't know as the tyres and tyre pressures were perfect. Maybe there's a balancing / tracking issue?
