I have a 2012 Peugeot RCZ which has done 20,000 km.
It has had a whirring sound in the rear of the vehicle. In December last the petrol pump failed and a new one was installed due to water and debris in the fuel tank.
For the last few weeks the noise had returned and it was discovered that water and debris is back in the fuel tank.
Any suggestions what is causing this. Had only travelled about 700 km on the new pump.
