Thread: Puma engine warning light query

Try All4x4 at Kotara, if anyone has they will.

This sounds like the noise a lot of owners are experiencing. Dullbird has posted an extensive thread on here somewhere. Seems to be no fix yet.

It is most probably not a major issue. We have become a little paranoid since Dullbird and Muddymech's unfortunate and real experience with theirs

Maybe just some damp in the fuel system...cold humid weather. The fuel pressure sensor on the fuel rail may have had a hiccup.

Happened to mine under similar circumstances.

I've heard that the light will go out after a short while.

I also read that undoing the sensor on the rail (there is a yellow release button on it) and giving it a wipe with a dry cloth might help.

Reading the fault code will probably only confirm that the sensor has picked up a fault.

Try these 2 threads:
So the PUMA goes back to the garage again tomorrow

Where do you keep your PUMA

Thanks Mahn. So far (having done another trouble-free 20km from cold) the engine light is still on. I guess if was going to reset it would have by now?

It usually takes 3 driving "cycles" to clear a fault, so long as the fault itself is no longer present. I'd still give your dealer and LR assist a call though.

Cheers,

Thanks Tim.
I have just followed Mahn's tip re the sensor (except it did not appear to be a sensor)and the engine light cleared immediately.
At the rear end of the common rail there is what could be an over pressure relief valve. Attached to that is a small-bore plastic pipe with a red quick release clip. I pulled it off and it dumped about 1 cc of diesel. After reattachment I started up and engine light is gone. http://www.aulro.com/afvb/images/smilies/angel.gifI am a bit baffled as I cannot see any electrical sensor connections in the area??http://www.aulro.com/afvb/images/smilies/angel.gif
My guess (and I am hoping someone can provide some real knowledge) is that the over-pressure valve lifted briefly and that the released diesel is sitting on the sensor keeping the light on.
Any better ideas?

I love this forum - in the old days we would have been flying blind - mind you they hadn't invented CPU's then and stuff could be fixed!!!!

Brian,

Something seems to have worked.

I think of this as being a cross between reading a goat's entrails and bush mechanics with a dealer as our witch doctor not knowing much more but having a gadget.

There must be a rational explanation.
