Engine Oil Light Passat

[mathoo19]

Hi. I'm having problems with my A4 Cabriolet 3.0. I had water in my fuse box and many other place and it messed up everything.
Had to change my oil sensor (bought a cheap one on Ebay)
Everything is fixed now but I keep getting Oil Sensor light on (orange) once the engine warms up. Temperature gauge works and everything is OK for about 5 miles. Then Sensor light comes on once it gets to normal running temperature.

If I let it sit the light goes off and comes back on after few miles again. VCDS doesnt read it as fault either.

my guess is that its a crappy sensor.
Any ideas?
Could it be because of cheap sensor or because my oil is right to the max?

also any advice where to get a OEM sensor?
I read that meyle sensors cause problems with temperature gauge so I want to avoid them. Hella maybe? not sure where to buy it. Found some on Ebay but they look as fake as the one I put in last week!

Audi want £90 for a sensor - 1J0907660B
Any chance I can get it cheaper elsewhere?

Hi there i had issiue with oil low light coming on IT TURNED OUT 2B REALLY WAS LOW THE DIPSTICK IS BAD DESIGN ITS BLACK SAME COLOUR AS USED OIL IF U CHECK THE LEVEL ON DIPSTICK IT DOES LOOK FULL IN THE END I PUT ELEC HEATSHRINK TAPE ON THE END OF IT YELLOW AND RECHECKED AND IT WAS SHOWING PART AS FULL AND REST AS LOW THINK COS THE SHAPE SCRAPES ALONG THE WAS TO BEING DIPPTED. (DO NOT ) LEAVE THE TAPE ON COS THE CONSTANT HEAT WILL BREAK IT OFF INTO ENGINE ONCE DONE REMOVE IT BACK OFF. you may be able use elec tape cut strip and wrap around and warm it up to take the dipsticks end shape use bright colour. If it is not really low after doin this try these steps ....

Hi i had same issue on my 2007 a4 2.0 170 bhplowoillight on (orange) oil was new and full ( MAKE SURE IT IS FULL) !!! easy order to fix
1: look at fuse 5 10amp make sure not blown( or goin bad / brown inside replace with good one)
2pen bonnet sray degreaser all around bonnet lach and use small swrewdriver and paper cloth clean ALL dirt an muck off even push lach into closed possion to get to other areas when fully cleaned spray with some sillicon lube or penatrating spray wd40 all latch( i came to the thought that maybe the latch contact links in with the sensors earth circuit ) there for dirt wont let it contact breakin the loop.
If not cured it
3: dissconect batt poss and neg for 20 mins to force computer into reboot
4: take out oil level sensor clean with elec contact spray replace and make sure plug wire is free from dirt.
5: STILL ON new sensor
6: make sure no fault codes on VAG-COM or AUDI £££$$$

Thank you I will try that!
VCDS or VAG COM cant find anything.

It only comes on once its warm.. and Fuse 5 is new as I had to redo my fuse box. but I will try the rest

Thank you

EDIT:

checked everything. Oil shows up higher on one side of dipstick. One side just under max line and one over max line.
bonnet latch is clean.
fuse 5 is new. Put it in on Tuesday


sensor light not on. But I am sure that it will come on as soon as I do 2-3 miles..

it just seems like it comes on once the oil warms up.
i guess I will need to stick another £90 into it.

If you want to be sure start on the level and flush and change the oil and filter, add 4L of 505.01 unless you have a dpf in which case you need 507 grade oil, if the light is still on after you have at best a cranky sensor and at worst a dying oil pump, which engine is it, is it a CR or a PD engine and also say which spec as you can still get an SE registered in 2009, I suspect it's a Highline model? which will be a 1.9 or a 2.0CR

Hi.
I'm not sure if you replied to me or the Passat post (i crashed VW thread with my audi issue )

I'm going to flush mine on Tuesday, possibly clean out the whole sump. See how it goes. I hope it will work.
if your post was for me than...I'm not sure which engine - ASN? but car is a 3.0 v6 Sport Cab.

Cheers
