I have search and found nothing.. my 02 type s w/ 97k miles appears to be having an oil leak from the oil presure switch. I noticed that there was oil leaking about 1 month ago. I cleaned the whole engine bay and sub frame of all old oil and grime. I just checked and it is still leaking I traced where the oil might be coming from and the oil presure switch has oil on it. I would like to know if anyone out there has this problem and if so how was this fixed? Also is this a common problem? Any info is appreciated. I have no warranty so I am not going to take it to the dealer.
