I wonder if you have an input to help me here. Car failed to start - engine started but then died immediately. The RAC said the car no longer recognised the key. My wife brought the spare key and we had no luck with that either. The RAC towed it to an Audi dealership in Berkshire. I checked with my usual garage and they agreed that it was an Audi job. Repaired next day, problem said to be "wire for reader coil connector making poor connection". Replaced wires, recoded keys. Charge - £176.67 for one and a half hours labour at £99.99 per hour plus VAT. Drove 5 miles home – OK. Next day: same problem. They asked me to arrange to send the car back. They had no transporter. They said I could use the RAC. I refused and said it was their responsibility. Eventually, they arranged collection. I have no confidence in these people. Any idea what the problem is likely to be? Is the above charge reasonable? Should I be charged again? They refused to assure me that I would not be charged if it was a different fault.
