sometimes in june last year my car started displaying thta there is something wrong with oil pressure, i took it to a local dealer. they told me that the sump was dirty and all they had to do was clean it. In november the same problem resurfaced. i took it back and this time around they said the oil pump and the sump needed to be removed and replace them with new ones. now in february of this year the problem was there again. what could be the issue because i'm starting to believe that these guys dont really know what they are doing. all i see are the enormous charges i'm getting from them
oil pressure problemd on 2002 Volkswagen Jetta
The repair procedure includes confirming the oil pressure with an independent oil pressure gauge. This is to eliminate the possibility of an erroneous display. Has this been done?
The root causes of the failure you describe are the use of incorrect oil i.e , non synthetic , and/or the use of the wrong oil filter. Over extended oil change intervals are also a factor.
If you are having recurring problems and actually have LOW oil pressure stop driving and get it properly diagnosed and repaired.
