From another website:
Last Monday I was driving home and the warning light came on saying the engine was overheating. Luckily I was just round the corner from home. Three years AA Peugeot Assistance was included with the car, so I gave them a call and the AA man was there within the hour. After testing the car he discovered the engine wasn't overheating, it was a fault with the engine temperature sensor which was a known fault on this model. I booked it in at the Peugeot garage for the Thursday. Wednesday morning I got in the car to go out and the engine wouldn't start. AA came out yet again (can't fault them!) It was apparently connected to the engine coolant sensor fault. He got it started again and advised me to take it straight down to the Peugeot garage.
They fixed it under warranty and I got it back the next day. They had the nerve to charge me for a courtesy car which didn't impress me one bit, but I guess that's decided by the garage dealership rather than Peugeot.
