Car Forum / Volkswagen / Water Cooled Volkswagen Cars / May 200782 Rabbit warning lights comming on
have two warning lights comming on one is the oil light, the other is in the middle of the temp gauge. Believe they are both sending unit problems.Want to know which ones they are, where they are, and part numbers so I can replace the wright ones. oil light on-do a oil pressure test coolant light on- coolant level, overheat, faulty gauge. > have two warning lights comming on one is the oil light, the other is in > the middle of the temp gauge.

While you could be right, but since they both may be indications of the same problem and they involve different sensors, I think I would think they are for real and I would be worried about possible damage.

Sometimes using the wrong oil can cause the oil pressure light to turn on. I had to use 20w50 on my 1984 or the pressure light would turn on. Pressure guage to confirm after you make sure the correct oil is in the engine. Sending usints ar on the head and on the oil filter housing. The pressure switches have different values. The oil temp and water temp sensors also have different values. The values are writen on the switches and sensors. They may not be correct but you have to report back with what values you have, what oil you are using and what your pressure guage reads for more help. > Sometimes using the wrong oil can cause the oil pressure light to turn > on.

I haven't yet reached this point with my Mk2 GTI but older VWs (Mk1 and Mk2s usually) as they age usually lose a little bit of oil pressure (where I don't know...maybe a slowly dying oil pump) and it'll get to the point that anything less than 20W50 will trigger the oil pressure warning. Being this is the beginning of summer, use 20W50, see if it works (probably will), and revisit the issue again when the weather cools in the fall (although I run 20W50 all year although being in SoCal I don't see temperatures lower than about 45F overnight myself anyway). |
