2007 Audi A4 B7, 2.0 TDI, 140.000km

my low oil level warning light was constantly coming up, regardles there were enough oil. It helped a while when I disconneted the battery for a while and then reconected it. The light stayed off then a couple of weeks, sometimes even mounths.
Then I get tired of this so I decided to replace it. The OEM sensor was Hella with VW part # 06E 907 660 and Hella part # 6PR 008 079 - 05. Since price of new one at the dealer was way to high I searche Ebay and bought me some cheap china crap: http://www.ebay.com/itm/121254660529...84.m1439.l2648
I told myself let's give it a try.
I repleaced the sensor and when I turn the ignition there was no warning light, but next day in the morning when I was driving to the city some other warning came up - oil symbol and next to the symbol was word sensor. When came home I connected my car to the pc and read the fault codes it detected two faults: 005716 Please check DTC Memory of Instrument cluster, 00562 Sensor for oil level / temperature (implausible signal)

I decided to get read of this cheap china crap so I thorouly cleaned the old one (I used gasoline and air compressor to blow out oil sludge from the iside of the sensor's housing. Then I reconnected it to the oil pan and when I turn the ignition the instrument cluster middle display still reported the sensor error. Then I once again disconected the battery for few minutes and now there is no warning. Even fault codes are not comming on.

Now I am asking myself, was the cheap china crap ok but just needed a battery to be disconected or what?
Please help.

Battery disconnect wont do anything. You need to clear the code with a scantool. And yes I have put chinese oil level sensors on a few times. first one didnt work after a day, the second one leaked oil through the electrical connector part....Id try for a slightly better aftermarket one, maybe on ECS tuning or something.

Have a good look at the wires in the connector plug. They have been known to break, so pull on them and make sure they are fine. Also check for corrosion on the connector pins.
