Default Re: 2009 MB Mondeo Oil Pressure Switch Faulty

So I got my car back tonight... $1000 later, they changed the oil pump... Only took them the better part of 2 weeks to get it sorted...

I had to work tonight, they dicked me around all day, finally pick the car up at 5pm have to go straight up to Sydney for work... Get 20 mins up the road, pull in for fuel... Same bloody problem again!!!!

Whenever the revs get low, oil pressure drops, oil pressure light comes on, accelerate a bit, light goes off and everything is fine...

Mechanic replaced Oil pump, drain plug gasket and used $154 worth of 5W30 oil... Still doing the exact same thing... Anyone got any ideas if it's not the oil pump?
