1994 volkswagen golf gl

Hi Brandon-Sorry to hear you are having trouble with your Golf. They are fun little cars. So if the sensor was changed but the chiming or beeping continues to occur, I would return it to the place where you had the oil changed. They should be able to reset the service indicator (which is the beeping you hear) given, that there are no other oil related issues that causes the car to throw the warning ping or a code. Are any lights on, on the dash? The oil light? I would check the oil in the car when it is cold (meaning let the car sit for several hours or even overnight). Ensure that it is at the proper level. I would be wary of having work on vehicle done at Express Lube, or Jiffy Lube, or any of those "fast and cheap" places. Here in my city there is a small little shop that deals only in VW's and charges about $5 more than one of the "quickie" places. These shops know about german automobiles are are more likely to do a job well, and correctly because they rely on customers coming back ( a huge chain store could care less if you come back or not, because they are so big ). The only reason I mention this, is because 9/10 oil related questions I answer here are due to faulty, botched, and sloppy jobs done by these "quickie lube" stores. Best of luck man!
