- - Faulty Oil Level Indication (http://forums.pelicanparts.com/porsche-924-944-968-technical-forum/201336-faulty-oil-level-indication.html)

There might be another variable here. We grounded the float level sender wire AFTER going to key 2, and AFTER starting it and the light wouldn't go out. We grounded the white/yellow wire at the flat 8 pin connector in the pass. footwell and it stayed off after we started it.
SOOOO, we grounded the wire in the engine compartment BEFORE starting it and it stayed off after starting the car. In other words, the parameter has to be met (ground) before the key is turned?

I had my clutch replaced a few years ago, and they did not get the master ground completely tight, which caused some rather weird indications and problems. As a result, the lasting problem is the the oil level indicator light comes on when the car moves.

I first thoought that it was a bad oil level sender in the pan, changed it, still have the problem. Next came a new ground wire from the sender to the pan, still have the problem. Then it was a new wire from the sender to the DME. Still have the problem. So we tested the old sender, it was ok. The wiring was connected to the old sender, and the sender was then attached to the chassis. Drove the car, slammed the gears, no light came on.

The current fix was to remove both the Master Caution and the Oil Level lights, not a good thing.

Can anyone help?????:mad: :confused: http://forums.pelicanparts.com/uploa...1105633113.jpg

Great photo Phil!

2005 was a good year.

I have been chasing this problem for a few weeks. Does your grounding solution solve the problem so the sensor functions as designed or are you just disabling the lights?

Installed a different level sensor. Didn't solve the light issues.

Can anyone verify that the sensor creates a ground when the oil level is full?

I can't verify but based on what I read above, if the sender / switch is high enough (not "full" but at its own limit) then the ground is completed and the light is off. If the oil level is too low, the switch won't ground and the light will go on.

This is pretty standard wiring for Porsche senders, so I'm going to guess this is the same here. But again, I'm just speculating. I'm having an intermittent light also so wondering what others are finding. Suspect my cluster, as there are other lights that go on and off (flash intermittently) from time to time, which is definitely not normal.

Picked up a used instrument cluster swapped out the odos and installed. Proproblem is solved.
