i keep getting confused people, some of us refer to the steering oil pump as the cause for the noise and others for the fuel pump, so which is the one? sry, I've asked this Q already, but I can't figure out what to tell my dealer :)

Mine was the power steering pump. My conslusion is different problems similar noise...

my sound came back ! 2days before i pick up the new one...i hope the new one doesnt have these problems

My FUEL pump was replaced.

I`ve asked technical division for input into this, as the truck has now been done twice already. Mine is the oil pump. Is the fuel pump replacement not associated with the power loss saga?

Cheers,

My oil pump was replaced and the sound hasn't come back. (crossing my fingers)

I'm sorry.. I was wrong.. It was infact the OIL PUMP that was replaced. For some reason my service rep was telling me that it was the fuel pump. After reading all of your posts I read my service receipt and it was indeed the oil pump.

Quick update here, had technical division out to access where the noise was coming from - loss of vacuum in one of the hoses and they are opening up the fuel line too so not the oil pump (apparently the oil pump issue is more in the earlier M models, so almost when production initially commenced). Will keep you posted when this is fixed.

Cheers,

well the new truck feels like a different beast, could just be the new seats idk but no bad sounds so far!

:popcorn:

Did you get comfort seats this time around? I wish they would offer those without the seat ventilation on the M..
