still learning my new vw. noticing that my oil pressure is all over the map. sometimes it sits midway, other times its 1/4. other times even lower than that. it never goes over mid point. i also notice a faint whine during cold start and it will last a couple minutes. anybody think this is oil pressure related? i'm having a laundry list of issues with this car and not being familiar with vw whatsoever has me worried a bit on it.
