Phantom Posted August 18, 2006 Report Share Posted August 18, 2006 Driving down the M1 yesterday and the tyre pressure monitoring came alive , 'Check Tyre Pressures', I did so and it turns out the front Driver's side tyre had gone from 40 to 14psi I thought it might be a slow puncture, so just taken it into Kwik Fit and they removed the tyre but couldn't find anything either in the tyre or anything wrong with the rim. So why is the tyre going down then ?, my guess is possibly a faulty valve? Any thoughts from the TSN posse Link to comment Share on other sites More sharing options...
Milo Posted August 18, 2006 Report Share Posted August 18, 2006 May well be a faulty valve. On a recent TSN meet, NiGhT drove to the Scottish Borders and found he had what looked like a puncture. However he had a mini compressor with him and after re-inflating it, it was OK and didn't go back down. It's nice to know your DIS works though Link to comment Share on other sites More sharing options...
Phantom Posted August 18, 2006 Author Report Share Posted August 18, 2006 Yeah I was curious to see what the £200 option gave me, wasn't sure if it would tell me which tyre was deflating or the individual tyre pressures, but 'Check Tyre Pressures' coming up on the DIS is better than nothing, especially from a safety point of view Link to comment Share on other sites More sharing options...
paul_tdi Posted August 19, 2006 Report Share Posted August 19, 2006 HI! I had the same on my car. First time it turned out to be leaking between the rim and the tyre and then between the valve and rim. I found the best way of testing was to mix a weak solution of water and washing up liquid and poured round the rim. Good luck in sourcing it!

Phantom Posted August 19, 2006 Author Report Share Posted August 19, 2006 Well I still have the problem, had to change the wheel today, when I took off the deflating wheel I noticed a load of scratches on it, bloody tyre monkeys at Kwik Fit, totally useless at removing wheels without wrecking them However the tyre monitoring system is still showing a deflated tyre, anyone know if the spare wheel is fittd with the monitor system ?, if not does it take some time for the transmitter on the wheel rim to sync up properly. Will have to take a trip to the stealers I think, glad I paid for the upgraded full size alloy Link to comment Share on other sites More sharing options...

On my car it lets me know when there is a drop of just 2 psi Waiting untill it gets to 14 psi is a waist of time as you'd be able to feel that the tyre was very low pressure in the steering.
