Bit of help needed please guys! Here's the story...
I have the 18'' monza's on my GTI. For about 2 months the NSF tyre has been deflating, each time the car flashes up tyre low its on 15ish PSI.
Changed the front tyres as they needed doing anyway, problem hasn't gone away.
Got the garage to check the wheel, its straight with no buckles or dents but they said they can't change the valve as its a metal VW part only. This is the part that seems to be leaking as small bubbles were appearing when under water.
Had the valve changed by VW, its now leaking air at a rate of full to flat tyre in 48 hours! The valve is silver but the rest are black.
Has anyone else had this problem? And does anyone know the part number for the valve so I can check its the right one!
Thanks in advance!!
