I just bought a second-hand car, and when I got it home I tried to check the tyre pressures, with a simple mechanical pressure gauge like this, which I've used for years on previous cars with no issue.
It was fine for 3 of the 4 tyres, but I couldn't get a reading for one of them - no matter how hard I pressed the gauge into the valve, or the angle I pressed it in at, it seemed to be unable to press the pin in. Looking closer and comparing it to one of the other tyres, it seemed that the pin was further inside the valve than the other tyre, or maybe the pin itself was shorter?
Is this a common fault, and is it something I should worry about? It's annoying not to be able to read the pressure, but at the same time feels like a very petty complaint to have to go back to the dealer with. It's a Volkswagen main dealer, and we paid 'main dealer' price for it, so I don't feel too bad about being picky, but just want to check if it seems like a reasonable complaint, or if there's maybe something simple I should check first?
