BMW E39 530d 2001 - Cam sensor waveforms wanted #

Posted by Sean Murphy on October 4, 2011, 9:58 am

Year of Manufacture *: 2001
Engine Size and Code *: 3000
( Optional ) Scanner Used: Autologic & Picoscope

I'm looking to cure an intermittent no start on this vehicle.

Does anyone have a bad/faulty cam sensor plot that i can compare mine against as i'm not sure it's 100%?

PS - i've looked at fault codes - none registered, checked supply fuel pressure @ ~2.5bar, scoped fuel rail pressure etc and all look ok at the moment but, typically, it hasnt not-started since its been here!

we had a simlar problem on2002 320d and found 8mm nut on ingition power supply near battery loose thus giving intermitting non start +rev counter would not work when cranking,its not the answer your looking for but may be some help.Con

fuel pressure reegulator?

Thanks for the advice guys - i'll check out that 8mm nut!
Fuel pressure looks fine, pre-pump and fuel rail, so i dont think thats the source of the issue. Definately smells like an intermittent electrical/electronic issue to me.

PS - 5 out of 6 glow plugs werent working, although i'm not convinced that would cause the randomness of the non-start as it happens engine cold/hot/dry/damp etc

glow plugs they have nothing to starting on this temperature in this system(I hope you have a common rail system in there).
For me if this would be electrical/electronic fault it should put the code in.But this is only my thinking.

Sounds like an ignition switch Sean. I have done a few.
