Volkswagen Repair: 1999 VW Golf, Oil Pan, Check Engine Light, oxygen sensors, helping relationship


Question
Hello - my mechanic told me that i had to replace my oil pan due to the bolt being stripped. That was about a week ago. Today, my check engine light went on - would it be because of the oil pan? Or am I looking at a completely new problem?

Thanks for any help in advance.

Answer
The oil light should come on if there is a problem with losing motor oil, not the check engine light.  I can't see why one bolt being stripped would require a new oil pan.  Is it the drain plug?  If there is still enough material left in the oil pan itself, it may be possible to repair the pan with a "time cert."  They are like a helicoil, only better, they seal completely, because, I think, they are slightly tapered, and get bigger as they go in, so the threaded hole they fill, they fill progressively more, and more.  They also stay in place for a much longer time because of the tighter fit.  The repair is not cheap, but is certainly a lot less than a new oil pan.  Maybe this is an option for you.  Things that turn the check engine on are;  oxygen sensors, secondary air pumps, catalytic converter efficiency, and the like...stuff that deals with the emission controls, and their performance, or lack of it will turn on the check engine light...normally.  Don't take your car to the cheapest place in town to get your oil changed anymore either.  Take it to a reputable, trained, and certified technician.  Ask your friends for recommendations, and let your full time technician be responsible for the oil changes, and the other maintenance, and repairs.  After you get to know him, or her, and after they get to know you, and your car, a helping relationship will hopefully develop, and you will be able to drive your golf for another 7, or 8 years.  Good luck, Gina.  I hope I helped you, and your Golf.
