Oil Level Sensor Failure 170 (BRD engine)

[sanstorm999]

Hello Everyone,
My Oil Level Sensor Part # 06E907660 (Hella Unit) has started to play-up on my car and will come on even when the Oil level is confirmed ok!
Audi dealer have quoted £84 and £69 from a local motor factors for a replacement.
Before I go out and purchase a new one I was wondering if anyone else has come across this problem on the 170 BRD engine and is it more than likely the Oil Level sensor that is at fault and not something else please?

The sensor is reset for a while when I open and close the bonnet BTW.
Also VCDS (VAG-COM) does not report any fault codes at all! (Tested while the Oil Level Warning light was not showing)

Many thanks

I've just had my sensor replaced whilst in for a service, I had the same problem but normally found the warning light would come on during a long journey. Open/close bonnet and it would be fine for a while. My specialist said it could be bonnet switch or oil sensor but when I told him that opening and closing bonnet reset the light he was confident it was the level sensor. It has now been changed and no further problems. It might be worth combining having the switch changed at the same time as a service - my Indy didn't charge me for the fitting of the switch.
Hope this helps.

Hi i had same issue on my 2007 a4 2.0 170 bhp low oil light 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 £££$$$
