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?

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

SOURCE: 1998 Passat 20V, 116K miles. Oil pressure warning

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.

I have a 1998 VW Beetle and Im trying to locate the alarm/buzzer that comes on with the oil light. I need to unhook it. ITS DRIVING ME CRAZY! HELP!!!


First thing, check your oil pressure. Even if you check the oil level, if the oil pump is going bad then the oil pressure isn't high enough to keep the engine lubricated- that's probably why you hear the alarm. You'll end up needing to rebuild the engine if you drive too much without the proper oil pressure. If you're really sure you want to disable the alarm you'll need to remove the dash to get to the buzzer and disconnect the wires. You can also experiment with removing the fuse for the instrument cluster, but you'll lose all your dash lights too. Good luck.

Have you checked your thermostat. Some cars do not have gauges for all componants of the car located on the dash board. A bad thermostat could drive the oil pressure gauge up, if there is not a coolant level gauge on the dash board.

1989 VW cabriolet oil pressure warning light on at low rpm and idle. Oil pressure gauge shows sub 1 bar at same time. Is this a sending unit problem, or an oil pump problem? Where are sending units? ...


The Oil light is a dreaded sight, especially at idle. Usually if an oil pump fails, it dies, the same with an oil pressure sender. I had the same problem with a 97 neon, at idle the oil light comes on... (192,000 miles). If the oil used at the oil change was a thinner viscosity than what was in there, that could cause it. If not, it could be bearings going bad on the motor creating a low pressure situation. I fixed it by going to a thicker viscosity, from 5w-30 to 10w-30, and in a week the light went off... this was 7 months ago. Just food for thought, hope this helps.

VW Golf Mk4 1.4 16v Oil Light Warning on Dash


Measure your oil at normal operating temp, without the engine running of course. This will give you a more accurate reading once the oil has circulated in the system.

The system works like this:
  • With the ignition on, the oil pressure indicator light on the dash should come on and flash. Once the engine is started, the light should go out and stay out as long as the engine is running.
  • If the oil pressure drops below approximately 0.3 bar or 5 psi when the engine is running below 2000 rpm, the light will flash.
  • If the oil pressure drops below approximately 1.8 bar or 27 psi when the engine is running above 2000 rpm for more than 3 seconds, the indicator light will flash and the buzzer will sound.
If either this two warnings occur:
  • The engine should be switched off immediately and the oil level should be checked.

The oil pump is relatively easy to change with the engine in situ if it is (commonly) at fault,
Get an oil pressure gauge with a pipe and brass fitting ready on, (borrow or buy cheap from boy racer shop), unscrew the sensor (or ask the garage to for a £5) and plug it directly into the sensor hole after you've been for a run.. When warm, mine sits about 40 at motorway speeds, ten at tickover.

Oil warning light will flash and buzzer will sound when driving


Well theres two possible reason for this, 1: the engine is worn enough to let the oil blow by the main bearings causing the oil pressure to be lower then OEM spec thus activating your oil light/buzzer or 2: your using the wrong type oil, you should be using 15W40 diesel grade in all 98 and older vdubs gas or diesel engines. Alos there is one more thing you could try if you have elliminated step 1 and 2, the oil pressure sensors do wear out, replace them both (high pressure and the low pressure) there are under $15 each and easy to change. Good luck

Gauges say no pressure in engine 1995 vw golf


There are two pressure switches. One for oil pressure and one for a dirty oil filter. Are you sure you've changed the right switch. If car drives for 30 mls it doesn't sound like you need an engine. The spluttering is likely to be completely unrelated to the oil warning I suspect.
