I got a puncture in my offside rear about 5 months ago and took it to the dealer as punctures are free for the life of the car. After checking my pressures a few weeks later the same tyre was losing pressure and I noticed the plug they'd used to supposedly fix the picture was sitting proud of the tread (about 10mm). Got them to look at it on first service and lo and behold the puncture still isn't repaired. Appears all they've done is trim the plug but it still bubbles when you apply water. Would you give them another chance to fix it properly or just go somewhere else and chance that they don't scratch/scuff the alloy (about the only thing dealer managed to do right)??
