Omega General Help / Water in spark plug well, 2.2lt petrol ecotec

« on: 14 February 2009, 12:08:00 »

2.2lt petrol auto 2002 ecotec CDX omega.

Had some misfiring problems, which were cured for a couple of months  by fitting new plugs and DIS pack.

The problem has returned. When I take the DIS pack out, I sometimes find mositure /condenation on the plug caps, and I have once found a tiny bit of water in the well of the spark plug nearest the driver.

Were might the water be coming from?
I can't see any sign of water leaks.
I've heard something about a heater valve that can fail?
Were is is?

Thanks

Omega General Help / Re: Xenon headlamp levelling controller unit

Thanks for the help. I was able to meter and compare both sides of the lights  from the contoller, and find the problem.
Problem was on one of the feedback potentiometers on one of the motors.  Water ingress, but not obvious from outside the case.

Omega General Help / Xenon headlamp levelling controller unit

« on: 27 January 2009, 21:15:36 »

I’ve got a 2002 2.2 CDX petrol Omega and I have a Low Beam Fld/Vision error on the dashboard display.
Normally this is due to a jammed suspension level sensor, and both headlights go to an extremely dipped position.
In my case both stick somewhere in the middle, in the same position. Headlamp motors look good. Suspension sensors look OK. So I think the controller is bust, or has lost power. Perhaps a loose plug.
 
Does anyone know where the controller is, and how I get to it?
The controller is the box at the top numbered 905659531 as shown on this post http://www.omegaowners.com/forum/YaBB.pl?num=1214429258/2#2

Many thanks.
