Yesterday at a petrol station I've noticed this shiny thing in my tyre. Visually the tyre pressure looks ok but I haven't measured it. I tried to lift it out and it looks like a bent nail. I do not want to pull it out as it might let the air out. Not sure if this puncture can be repaired as it is close to the side. I need to get it checked out tomorrow but I haven't had to repair / change tyres on an Audi yet. Do you have any recommendations? I assume audi dealer would be most expensive choice. I live in North West London. Any places locally to me I should check out?
