My wife bought this used Jetta a couple years ago. I just noticed there is an oil pan skid plate around the oil pan. Between the oil pan and the skid plate there is a sponge that is saturated with oil, though I do not see any oil on the ground after it is parked.
Are oil pan skid plates usually an aftermarket addition?
Does anyone know why there would be a sponge on the skid plate? Is it a bad that this is saturated with oil? Can I just remove this sponge and not replace it?
