Oil Light

[crawfy]

Allright for all you 300TDI owner's!!! ops:
Has anyone had an occasion where their oil warning light came on? Pulled over checked the oil, and any other telltale problem's?
This happened today when my wife was driving home!!! I have only recently done a oil change and filter. When I dri=ove the vehicle tonight I couldn't get the lamp to illuminate!!!!
Could it have been an intermitant fault? or have I used the wrong grade oil, I have started to use the Penrite light Diesel oil with a Morey's oil conditioner?
I'm not to concerned at the moment as the oil level is fine and when I checked the system while engine was operating everything seemed fine?
Any one have any thought's!!!!
Please don't mention Oil pump failure!!!!!!!!!!! [img]style_emoticons/<#EMO_DIR#>/sad.gif[/img]

Why not put a t piece in line with the sender and fit a gauge so you can see what is happening.

Not a bad idea!!! 8)

ops: You wouldn't hear about it !!!!
I had a air block in front of the sensor!!!! ops:
Re did the oil and filter and actually filled the filter with fresh oil before twisting it back on, it's amazing what can happen when you do thing's right the first time!!!!!!!! ops:

Doh it's back again!!!!
I have what appear's to be some oil pressure as when I took the filler cap of oil is seen pumping around the top, and when I remove the Dip stick oil spit's out the top!!! ?
The light will only come on at idle, as soon as you increase the vehicle speed or rev's pick up above 800rpm it goe's out!!!! Could it just be a faulty sender unit!!!!
I am also wondering whether the Morey's oil conditioner mixed with Penrite Light Diesel Hpr could be affecting it?
Any though's people? [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

You could try a new oil pressure sender. They are only a pressure switch and if the contacts inside get gungey then they don't work too well when the pressure drops at idle. I have had one pop the switch mechanism right out and spew oil everywhere! (XF Falcon I was driving at the time). If it still does it with a new switch, maybe the oil pump could be losing some efficiency and if it only happened since you used a new recipe of lubricant, maybe go back to the old recipe and see what happens. 8O

Just a thought, anyway. [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

I still reckon I'd put a cheap gauge on it and see what pressure it has.

What sort of pressure should he be looking for shaunp?
