I read the codes and sent the guy down the road. I really don't want it in the shop when the engine finally locks up. I suspect the first owner probably changed the oil per BMW requirements and the screen over the oil pump on the suction side has some build up on it. I told the owner what it would take for us to resolve. The other thing I'm reading is that the chain guide comes apart and the debris blocks the oil pump pick up which seems to be the diameter of a US quarter.
I would not wish a BMW on anyone.

The long change interval also causes blockage/failure of the oil pressure sensor which is next to the oil filter, when it blocks the ecu makes the oil pump ramp the pump to 100% cycle (highest pressure)
but the N20 engine you just saw is a gift that keeps on giving
if its not the timing chain, its the turbocharger itself, LOL
