Why would this be coming on? Ive checked oil levels and the seem fine? Any ideas? Im going to do an oil change this weekend so would this maybe put the light off? Thanks for your help:yes:
 
Could be a dodgy sensor or might be an issue with your oil pressure! Try doing an oil change and see if that makes any difference. If you have a pressure issue you really dont want to be driving the car too much.
 
Mines the same that annoying beep and the oil sensor warring light, im sure this just relates to a faulty sensor. iv just had a service and its still beeping away but at over £70 for a new one ill live with if for a while.
 
If the light is red, stop driving and get the pick up in the sump changed before it costs you an engine
 
Yep, change the sensor, if light is still coming on then have it looked at as it may be a blocked oil pick-up or faulty pump.

Get the car scanned, it will be rare for the sensor to be duff but a VCDS scan will tell you. It will be easier and cheaper to get the oil pickup checked and cleaned/replaced rather than spend £80 on a sensor that might not be the problem.

Out of interest, how much approx for a new pick-up and oil pump + labour.

DC.
 
You shouldn't need a new pump or pickup pipe, just a clean and a new strainer which costs a few quid. A new pump and pickup pipe wont be particularly cheap.

My mechanic charged me £80 to remove the sump, pressure test the oil pump, clean the oil pickup pipe, and replace the strainer (filter). But he was already doing a service so the sump was drained of oil anyway.
 
i had the same problem 3 weeks ago. its the oil pressure/ faulty sensor.
deffo worths changing it, before you do some serious damage to the engine.

I've got the same problem
red light with 3 beeps

Oil levels are fine, i think i put a little too much in since i didnt really have the car on level ground and it messed up
this was after i busted my sump and fitted a new one in

Vagcom didnt throw up any errors regarding it

i was told by a friend, its probably a faulty oil pressure switch. Been driving the car for the last 2 months been absolutely fine in every way
Its due a service nowish,
so will be changing oil again and new oil filter etc

hopefully itl go away. anyone know what else it could be

Dont europarts have the oil pressure switch for under a tenner
 
My light isn't red though its orange and has an oil can with sensor written beside it. Your problem may be bigger than mine by the sounds of it if it's red? :sadlike:
 
How can you drive around with that thing flashing.....it would be mind wars with me......it bugs me when the washer fluid is low.....
just think of a worse case scenario ...if it is on because of a dodgy switch, what can it do extra if things become worse and the pressure actually drops....it would not do any extra warnings....... that is your final warning!!!
 
It's been 4months and about 3k miles lol
Will have it checked out by a mech

Mind you
It doesn't do his at high speed or motorway
But as soon as I drop from high to low speed
The light beeps
 
I would think that at high speed your pump is working harder and pumping the oil at a higher pressure, at lower speed the pump is working less hence less pressure, i may be wrong about this, but i would be a little concerned if i were you.

It's either your pick up or your oil pump. Either way if you have the sump off to do the pick up, you may aswell do the pump at the same time

What service are you on, longlife (5w30) or regular (5w40,10w40)?

Becareful with over filling these 1.8T's, a friend of mine mistakenly thought the low oil pressure warning as being low engine oil and overfilled his 1.8T on his Passat, it was halfway up the dipstick! He's an old chap mind, and he never thought of checking his dipstick first before filling! Anyways, the results of this is the oil came up the breather and filled the intercooler with oil, and it also pushed a load of crap into his sump, which blocked the oil pickup, so no oil pressure and a seized engine!!
 
I'm going to change my oil when I service my car in the next few days
Putting 5w40 in

Whilst I had these probs I just put in castrol 10w40
Just to double-check there wasn't any leaks elsewhere
I've verified that

So now its just do te service and hope the noise goes away
Really annoying an worrying sometimes

It is indeed

It was always meantto be temporary
It was put after the sump job to ensure that everythig was fine

Just haven't had time since then to change it since I'm moving between Manchester and Sunderland
 
If its yellow and says "SENSOR" at the bottom its a fault with the oil LEVEL sensor, which sits in the sump and registers how much oil is in the sump.

If its this, then its possibly just a wiring fault, or a sensor fault, and isnt a big issue so long as there is actually oil in there.

If its RED and says nothing at the bottom, its PRESSURE related, and continuing to drive the car will most likely result in a wrecked engine.

Did my oil change today found the problem, the oil sensor had become unplugged, problem solved thanks folks :D
 
hopefully my problem sorts out just as easily :)
 
Boys,
Had this happen to me tonight. Yellow with sensor underneath. Happened after a hard drive (in the rain) once I slowed down in the city. Question; If my oil level is good, can I drive 25 minutes to a mechanic without worry?
 
No you cant drive it, if your pressure is low you risk serious damage as your bearings will burn out. I've learned the hard way.
 
Reviving an old thread here for peace of mind.

This morning my car beeped at me with the yellow oil sensor symbol. This was before I even cranked the engine, so i'm thinking faulty sensor.
When i read this here, this would mean I'll have to change the sensor or check the wiring, but would still be safe driving the car (while keeping a keen eye on the dipstick of course)
 
Just for the interest of anyone reading this. My car has been loosing oil, so the yellow is definitely the oil level, just top up whenever the light goes on and you'll be fine.

Since then the car developed the red light problem, so I'm now looking for a solution to that one :-(

It is caused by a switch sticking in the bonnet catch, strip it down and clean and lube it, make sure it pops right out about 5mls I pulled mine out and pushed it in a few times, it was sticking in.
See this link for details but it’s an easy fix, 30 mins.
