My car has been in the local dealership for the past day and half due to an Engine Warning Light coming on - on the DAY I BOUGHT IT!!!!

Anyway, turns out its an o2 sensor that they've replaced. While they had it they also replaced a dented tweeter grille, a missing rubber gasket from the top of the drivers' side headlamp and also tried to sort the incredibly annoying squeeky roof.

Anyway, upon collection this afternoon I noticed a whine that wasn't there before : ( I carried on driving rather than taking it straight back just in case it was me, and the noise had always been there, but no, its definately a new noise.

So I called the dealer and they're taking it back in tomorrow. : (

I'm thinking its the LPFP in the tank. But why would it suddenly start making a noise? Surely chaging the o2 sensor in the exhaust couldn't cause this??

I've tried to do a recording of the whine and uploaded it here (.mov)

For those that have also had this issue, does this whine sound like your whine?

It sounds as if its coming from behind the drivers' seat (RHD car) or near the rear wheel...

Anyway, fingers crossed the dealer hear it and sort it.
