Question about 1986 Volkswagen Wagon Camper
First make certain you have sufficient oil.
Then check coolant level.
If both are OK, you may have a goofy sensor. The one in the expansion tank is particularly prone to cracking and giving weird readings.

Start checking the oil level, if oil is low then the problem is a leak or weared rings.
If oil level is ok, check that the oil pump has enough pressure.
If oil pump is also fine, then scan the ECU (car computer) and replace the sensor if you do not find anything else being wrong.

The throttle body may need to have a re-learn performed. This can only be done with a shop with a VAG system or the dealer. One of VW's great ideas, an electronic throttle body. Double check your coils as well. You may be getting spark, but not enough. I had both of these issues on an 03 Passat a couple of weeks ago in my shop.

The thermostat will show what the guage shows. the seal on the coolent bottle can be checked for tightness. so it could be a faulty sensor?

I found a link that may help it is for a shop manual it includes the long wheel base and TDI models 1.9, 2.4, & 2.5 cost is $35.95 US
You will probably find it cheaper on Ebay there are several listed there NOW
Sorry I could find nothing listed for OWNERS manual you should try a salvage or breakers yard for that
Hope this helps

Ok, first thing to do is to spend the $10 for a manual oil pressure gauge, available at any parts store. Hook the gauge up to the port where the oil pressure sender is, and see if it acts the same way as your original gauge did. You can even place it inside the car if you wish, mounting it either permanently or temporarily, whatever your wish is. You may need an adapter to make it fit the port, available at the store that you bought the gauge from. If it doesn't act the same, you have the choice of keeping the added gauge, or having your instrument cluster checked out and repaired(which can get expensive). If you are indeed having oil pressure issues, then you could be suffering from a filter that's too restrictive, a faulty oil pump, or need to go to a thicker oil, given the higher mileage on your car.
