I just watch my oil pressure gauge, but now I'm ordering some replacement sensors. Thank you so much for these videos. We own three of these Cabbies, and it's a pain to figure out a lot of the quirks!

[@OlisGarage]

The system is actually well designed with a redundancy. You have a sensor for the warning light, and a separate sensor for the gauge. So, if one of those sensors fail, then you have the other to cross monitor performance. Maybe it was a redundancy, maybe it was just easier for it to be designed that way. However, I know that helicopters have a similar design for the engine and transmission oil pressure indications and the associated cautions. Glad to hear the videos are helpful. Hope they keep the cars on the road!

[@OlisGarage]

Cyprian Pawlikowski good to hear!

[@KStewart-th4sk]

Just a note, the high pressure one is actually a switch. The Bentley manual refers to it as a switch. I believe the term "sensor" is actually used for a component that, in conjunction with a gauge, measures pressure or temperature. Although there are many other types of sensors too besides a sensor/gauge combo. A sensor would have an internal resistance which would change in reaction to a change in temperature or pressure (coolant, oil) to give you an actual indication. I have the feeling you are well aware of this and inadvertently said "sensor".

[@OlisGarage]

K Stewart you are correct. I mean, in a way it is a sensor giving a binary value of “yes” or “no”. Not trying to get into an argument at all. I could’ve been more clear. Appreciate the feedback!

[@OlisGarage]

Have you done the tests outlined in the video? The system is only designed based off of rpm. Not speed. Try revving the engine above 2000 rpm for about 5 seconds and see if the light comes on (like I do in the video).

[@josemariacabrerorivas6405]

Nice Oli ¡ Thanks from Spain

[@OlisGarage]

Thank you!

[@joeshmo475]

For the first sensor on the oil filter, you said if it spikes when ground everything works and you just need to replace the sensor. Does that mean it isn’t suppose to spike when ground or it is?

[@OlisGarage]

Watch the video again and it should be clear if you watch the inset video along with my arm motions. But I’ll also briefly explain. Grounding the wire should cause the temperature gauge to indicate an infinitely hot temperature. If your oil temperature has been indicating incorrectly, and your gauge spikes when you ground it, then replace the sensor.

[@abelardoarcos6595]

Based on your analysis, and on what you said on the last minute of the video, would it be safe to say that if the light stays on after u start the car, the problem is the low pressure sensor or canister like you called it?

@@CandyBond83 what caused you to blow the fuse? These things are always simple. Not easy, but simple. Bust out the multimeter. Check that the fuse is getting power on both sides.

Unless if you saw smoke rising or were snipping around on wires for fun.

[@patrickcannell2258]

I have installed an oil pressure guage. Piece of mind.

[@OlisGarage]

Is it a mechanical one or electric with sensor? The gauge in the center console works great, especially if the two pressure switches work. Quite frankly, a gauge and a pressure switch is also how military aircraft are designed because it’s a great redundancy. That’s why I never bothered to fiddle with installing yet another thing. I have two switches and a gauge. That’s enough redundancy for me. If one of them breaks, I just have to fix it ASAP so that there is a redundancy again.

[@kellysutherland8298]

I did all your tests. This was the result Blue wire did nothing whether it was connected or grounded. No light at all except the battery light but I dont think that has anything to do with the battery. I tested the High pressure sensor..... nothing happens when connected but light blinks at more than 2000 rpm for 2 seconds.

[@OlisGarage]

Kelly Sutherland do NOT ground the blue high pressure wire for the test. The key is to NOT ground it. If you ground the blue wire, you tell the system the high pressure switch works. (The way that sensor works is that it closes or grounds the system over 1.8 bar). You need to disconnect the blue wire. Start the car. Oil light should be off. Rev to 2500 for a few seconds, light should blink until you shut off the vehicle. If this occurs, then the system works properly and your high pressure switch is bad.

[@coryclaypole5710]

@@OlisGarage Hey Oli! This last response seems counter to the video itself, but it's likely me misunderstanding. So I understand, if I am experiencing the light blinking after 2000+rpms with switch plugged in run this test: on the high pressure switch, disconnent the wire, start the car (light should be off) and rev to over 2000 for a few seconds...if light comes on with that switch disconnected, its the switch that needs replacing (don't ground at all during this test)?

[@OlisGarage]

@@coryclaypole5710 start watching around 4:00. But you’re mostly right. We need to test the system. So we first tell the system that there is no oil pressure (sensor unplugged and wire dangling). The light should blink over 2k rpm. Then we tell the system the oil pressure is good by grounding the wire. The light should not come on over 2k rpm. I do both of these tests to test the two conditions of the oil pressure warning system (pressure is good, pressure is not good). If it passes the two tests, then you know your electronics are good and the switch is the issue

[@Guillotines_For_Globalists]

My Mother had a 1982 Volkswagen Jetta N/A diesel until 2003. The oil pressure warning buzzer would turn on all of the time very frequently. She would whack the dash until it went off. It was at the mechanic so many times and NONE of them could repair or disable, not even the dealership techs! BUT WHY could none of them disable the buzzer? By the way her Jetta had the 3 cutouts for gauges in the low section of the dash but they were empty, I remember 20+ years ago she said it was for some performance package or something sporty oriented that she didn't buy at the time of purchase back in 1982.

[@OlisGarage]

Hmm, I have no idea how the dealership couldn’t fix that. It isn’t a particularly complicated system. Interesting about the 3 gauges. I’d never heard that cars were sold with the cutouts but no gauges. Not saying it didn’t happen, I just hadn’t heard that before. They were great cars though. The diesel was a little slow, but they ran forever.

[@Guillotines_For_Globalists]

@@OlisGarage This was during the year 2000 or 2001 at best - nearly twenty years since the manufacture of this German-made car. Also two other independent mechanic shops. One of them claimed to have fixed it and then on the drive home I remember the buzzer went off again. Everyone was always stumped. But yes the 3 gauges at the bottom weren't there, but the 3 holes were. If I recall there was a black Jetta cover plate (like a delete plate) over them with silver text.

[@davidsalvadorvelazquez7365]

If I already change all the sensors, it may be that this wrong ?? oil change and oil drain cleaning

[@OlisGarage]

Are you running the correct oil for the temperature? In warmer climates 20W50 is recommended. If you change the sensors and the problem persists, find a mechanical oil pressure gauge and measure the pressure. If that indicates low, you probably have engine issues. You can try upgrading to a high volume pump which may also help. I have a video of that as well

[@fab3831]

Oil, so I did everything you said here which fixed all the issues but it now created a new one. With car at temperature in idle showing 1 bar, the oil light blinks, when I step on gas pedal pressure goes up and light stops blinking, but it always blinks at idle. What could it be?

[@OlisGarage]

Either you have actually low oil pressure at idle or your low pressure sensor needs replaced. Not sure what you replaced/fixed. Run 20W50 oil (assuming it’s somewhat warm where you are) and a Mann filter.

For anyone here that has the Grey Robert Bentley service manual for Gas,Diesel, and Turbo Diesel 1985-1992, those twits have the location of those 2 switches ass backwards. THE MANUAL IS WRONG! The higher pressure switch (yellow wire) is on the oil filter housing and the low pressure warning switch is on end of the head (blue wire, black stripe). Given that i had paid something like $90 for it back in 1991 when i bought a '91 Jetta TD new, i am rather Pissed. Am having a problem (intermittent also) with my 1986 TD and just discovered this. My '91 had gotten totaled by some a-hole running a Red, would have had the board from it, but another a-hole stole the whole car off a property where i kept it. I did have the engine out of it which i kept before the car was stolen. The location of the switches in the '91 are exactly the same as the '86 with the location of higher and lower ones the same.

Hi my mk1 golf sensor was replaced but oil light still come

[@profesinue9670]

where I find the color code of my cabriolet, I want to paint my car

[@OlisGarage]

profe sinue white sticker in your trunk. Should be on the metal bar closest to the rear seat.

[@lukaslubys1505]

I think so you incorrect while saying that blue wire is high pressure, but it's actually wire BLUE D01 (Low Oil Pressure Switch) also same with yellow wire is it actually YELLOW D21(High Oil Pressure Switch) ,but it's not a low pressure switch.

[@OlisGarage]

Nope, that is incorrect. The Bentley manual is wrong. Watch the video and see how the car reacts when I unplug the respective wires. I triple checked to make sure I was doing it right.

[@lukaslubys1505]

@@OlisGarage Maybe you are right, because I tried to wire up how I just said, but in that way no flashing light. In your way it started to flashing continiously. When started the engine the flash turned off. :))

Also könnte ich ohne weiteres machen. Aber dann würden nicht so viele Leute es verstehen. Ich habe es mir aber überlegt!

Mine blinks at low rpms

[@OlisGarage]

Aldo Torres so you turn on the key, start the car, and it blinks and never stops?

[@acuracer23]

Oli's Repairs after it warms up, it blinks under 2k rps at idle. I already replaced the water temperature sensor and it still blinks. Thanks for the reply! Keep up the great videos bro 🙌🏻👍🏻

[@OlisGarage]

Aldo Torres what is blinking? I’m assuming the oil pressure light. what oil are you running? What is the average temperature outside? My theory: you’re using too thin oil. Cabby-info.com mentions that a ton of people run 15w40 or even 20w50 in the summer. Appreciate the kind words! :)

[@acuracer23]

Oli's Repairs im talking abt the coolant temperature. Weather here in cali is abt 70’s rn. The oil problem its something else i need to work on. Replaced both sensors and added some lucas oil to thick it a lil. Havent gotten on the road yet cuz im working on the interior 😅

[@OlisGarage]

Aldo Torres I’m assuming you have a 1990 or newer?

[@ashikdossajee7533]

My mk1 the oil light doesn't flash with ignition on, infact I've never seen it light up ever but the car still starts fine. What could be the issue?

[@BradMeehan]

Mine seems to blink when I brake. Any ideas? It's a 92.

[@OlisGarage]

Is your car filled with the right amount of oil? That's my first thought. And when it starts blinking, what does the oil pressure gauge do? Does it also show a drop in pressure?

[@BradMeehan]

@@OlisGarage It was full. The pressure would drop to around .5 on the gage when I would brake. The ambient temp was high 90s F so that mat have contributed to the old oil + low pressure issue. It's a new-to-me car and i changed the oil and it seems to have resolved the issue. I'm excited to have found your channel. I'd love to see how to remove door cards, etc to repair locks, windows, etc if you have a video wish-list. The holy grail would be a top-replacement video, as there are no good references with the level of detail you give to your content. Keep up the great work. I'm learning a lot from you.
