Low Oil Pressure Warning -2008 Passat Komfort 2.0 Turbo. The check engine light and low oil pressure warning came on at 88,000 miles.

the mechanic you took it to was vw certified? if not replacing engine is cheaper than pulling one out and tearing it down? especially if you do take it to the dealership

i would say that u should use a motor flush to flush out the oil slug and replace with new high grade oil

i dont recommend the motor flush it will only make the metallic filter on the oil pump get all the sludge and clog. the sludge is caused by the oil not an vw defect. you need to change the oil more regularly and maybe change the oil you are using. the sludge appears because of the rest of the unburn fuel goes to the crank case through the piston rings and contaminates the oil causing it to create the sludge.

i had the same issues cost me to put a new engine as well.
