#7 of 70 Re: OIl Warning Light [rtc1]
Mar 15, 2007 (8:24 pm)
I have a 1996 VW Cabrio. I had an oil leak a few months ago. I had to have both (there's two) oil switches replaced. A few days after they were replaced, I noticed that the oil light would flicker intermittently, as well.
BUT, as I further studied it, the warning light would flicker when I was idled. And as soon as I tapped the gas, the light would stop blinking.
It just does it randomly now.
I was reading online about vanagons the other day, just for kicks, and I happened to come across an oil pressure related problem that someone else posted. I don't know if this is any revelation to MY problem, or the problem you have encountered. But it seems to make sense. It might just be sending a wrong signal out.
Here's what the other poster wrote:
Problem: Oil pressure light comes on under 2000 RPM
I recently experienced a problem with my Vanagon that seems fairly common. When the engine is hot and I stop at a light, the oil light begins to fade on. It doesn't go off again until the engine revs above 2000 RPM. (An explanation for this behavior is given below.)
EXPLANATION: While there is a "high" pressure switch and a "low" pressure switch, they both cause warnings when the oil pressure drops too LOW. Since "too low" is a bit of a subjective thing in an engine, VW decided to implement two standards. The higher the engine RPM, the higher the oil pressure should be. If you have just one oil pressure switch with a setpoint low enough (say 4.4PSI, 0.3 bar) to not engage at idle, that leaves way too much slack for when the engine is at high RPMs when the engine should have at least 13.2 PSI (0.9 bar) . The "low" pressure switch is used to alert the driver if the oils pressure dips too LOW while the engine is running at less than 2000 RPM and the "high" pressure switch is used to alert the driver if the oils pressure dips too LOW while the engine is running at more than 2000 RPM.
Mine seems to peculiar in that it comes on solid, not flashing. Nobody seems to be able to explain this.
There are 2 categories of causes:
Incorrect oil sensing system - Your low pressure switch may be bad. According to Ron Salmon of the Bus Depot, there are 2 specs of sending units from VW and one has a lower tolerance than the other. Your oil pressure may be hunky-dory, but the sender doesn't think so. It could also be a bad connection somewhere.
Also, check the connections on the oil pressure warning systems. Sometimes connections to the idiot light and from the sending unit can get weak and cause a false alarm.
Real oil pressure problem - don't panic yet, it may be simple. Some people have reported that Fram and other non-VW oil filters cause higher pressure drops because of restrictive flow. Try a VW "Autobahn" oil filter. Also, I was running SAE 30 oil; try 20W50. Another common problem is the oil pressure relief valve may be sticky.
Does this make sense to anyone else?
My car runs fine... it's just randomly the light blinks.

Help! I just bought a 2001 Carbrio and the check engine light won't go off. The brake light will come on and the milage and clock by the speed o meter will go off while I am driving. I have trouble starting it and often when I put it into park the car will stall out. I have had it in the shop 4 times already and it isn't fixed. It goes in again next week. Has anyone found a soulution to this?

I recently bought a 2001 Volkswagon Cabrio. It has 42,000 miles on. .. The car runs very well but there appears to be some problems, but i'm not 100% sure.. From what I have read here, i'm not sure if I have made the right decision to buy this car. The engine light comes on (this is two weeks after I bought the car).. One of my friends says that it could be the oxygen sensor. Also the brakes are working very well, but are squeaky.. and sometimes when I start the car after about a day or so of not using it; there is a noise for about 20 min and then it goes away... I was just wondering if any of these things, could be major problems in the future... if anyone has owned this car and knows more about it, I would like to know .. . .thank you very much !!!!

i have a 2002 cabrio purchased brand new and for 3 out of the 5 years ive owned it the check engine light remained on. i took it to two different vw dealers and an after market mechanic, no one could fix the problem. last year, in ny, it became mandatory for a check engine light to be off to pass inspection so i was in big trouble. they kept telling me it was the gas cap. after changing the oxygen sensor (twice) they eventually changed a $10 hose connecting the sensor to the vehicle...no more check engine light, that was last year.

thank you for your feedback . ..
I was just wondering, what hose it was that had been replaced to get rid of the 'check engine'. ? .
actually my 'check engine' light went off now, and the 'air bag' light came on; but i just want to know for future, in case it comes on again . .seems that it's just playing games. ...

I have a 1998 cabrio that i bought used from the original owner. when i bought the car she told me that after it rains or if the car has been sitting for a while (a couple of days or more) the first few times that you press the brake, the car will make a screechy, grinding sound. And, yup, it's true. i've owned the car for 3 years, and it does make a scary sound after rain or sitting. i've been told that it's due to either a little bit of dust or rust on the brake pads. nothing to worry about. the brakes also squeak frequently, but that's b/c the rims get really dirty and the dust settles on the brake pad. if i am diligent about cleaning the rims, the sound disappears.
hope this helps.

thank you for your feedback ... was just wondering because it sounded like a belt or something.. but the weird thing was that the car was running very well . .that's why it was suspicious. .
thank you again ...

Also, I was wondering. .. how has the car been running since you bought it ? .. I mean did you have any major problems. ..
I bought this car over a month ago now.. (it's a 2001).. and it began making noises (as you have mentioned after rainy days usually).. the brakes were squeaky, the car engine light came on, and the airbag light came on.. then after reading some of the comments made by different people, i became worried that i might have got ripped off.. your feedback really helped me though. ..i feel better..

Does anyone know whether any of these things below are suppose to prompt the check engine light to go on?
Headlight blew out one bulb
The reading lights don't work
The radio needs to be activated (new battery de-activated it)
I hope it's gone on for one of these reasons nothing mechanical.

If the radio is in safe mode than you need to go to a Volkswagon dealer so they can give you the code for it.. .
It's a safety option, so thieves can't steal it..I had to do it for mine. ..
My engine light and airbag light is also on.. the car has been running very well though..
hope this helps
