Omega Electrical and Audio Help / Xenon headlights dipped beam too high - any ideas?

« on: 23 March 2015, 00:46:05 »

On my 2003 3.2 Elite estate, the dipped beam is far too high. I keep getting flashed at, and I have also parked up on a straight section of road at night, and checked the dipped beam from an approaching vehicles point of view and they are dazzling.
I have changed the front level sensor on the f/n/s wishbone, which made no difference at all. I am not getting any messages on the display.
Whether it's just coincidence, this problem has only started since the gearbox was removed, overhauled and replaced, hence the reason I changed the front level sensor thinking that it may have been knocked or damaged during the gearbox removal.
Any thoughts would be greatly appreciated, as I can't used the vehicle when it's dark!!!
Thanks.

Omega General Help / Help in diagnosing EML fault codes!

« on: 26 September 2013, 01:34:49 »

On my 51 reg 3.2 Elite, the EML illuminated on the motorway, but the actual running of the car hasn't been affected. It has done 101k.
My local VX dealer kindly plugged in the Tech2 with the following faults codes -

P150 (9)
o2 slow response
Bank 2 Sensor 1
Bank 2 Sensor 2 (x2)

The codes were cancelled, but the light came back on after about 10 miles and I have noticed the odd 'wiff' of fuel from outside the car.

I am assuming that Sensor 1 is the front o2 sensor / Lamda sensor on Bank 2 and is the likely culprit.
Is it possible that this faulty o2 sensor is causing the codes being thrown up for Bank 2 Sensor 2.
Incidentally, I have read the very informative fuel trim / cat efficiency topic with great interest.
 
Could anyone explain what the code P150 (9) refers to, and also which is Bank 2 ?!!!! Nearside or offside of the car???

Would replacing the front o2 sensor be the first thing to do to possibly cure it? I have also read somewhere that the recommended interval for changing the front o2 sensors is 100k?

Thanks in advance,
John

Omega Electrical and Audio Help / NCDC2013 or 2015

« on: 21 February 2013, 15:33:36 »

Hi,
I have read all the posts as best as I can about problems with the NCDC2013, but was looking towards those with more knowledge than me for suggestions.....
I currently have a 2003 3.2 Elite estate with a NCDC2013 and GID fitted. It spits the sat nav disc out within a few seconds with the message 'insert disc with printed side up'. It has worked intermitantly, and whilst working everything seems to do what it should.
I have also got a 2013 and GID which I took out a scrap car, which weren't depaired, but I have the car pass for them. I haven't been able to test them.
I also have a 2002 3.2 Elite saloon, with a NCDC2015 unit with CID in it which is working great, with telematics (which I'm not too bothered about as I haven't got a sim card for it) and I am quite impressed with it!. I bought this car for parts originally, but overall it seems too goood to scrap. I don't have a car pass with this car, but I'm sure I could get one from VX.
The question is -
1 -  can the fault be repaired cost effectively, or
2 - could I simply replace the unit and GID with the paired ones from the scrap car as I have both the car passes for the scrap car and the recieving car,
3 - assuming that I do scrap the 3.2 saloon, could I replace the defective units with the NCDC2015 and CID without any further wiring issues as I'm not interested in the telematics at this time?     
 - Would I need the the units depairing prior to removal?
 - Would I actually need the car pass from the donor car to fit them - i.e. for any radio code?? 
I know a techy at VX who would help me out with any tech2 adjustments.

I know this may have been covered before, but I'm not the best at understanding car electrics, so some positive suggestions would definately be appreciated!!

Many thanks,
johnnydog.

Omega General Help / Differences in auto gearbox

« on: 07 October 2012, 23:01:05 »

I have been unable to find any particular reference to this in previous posts -  is there any actual difference between auto gearboxes, say with 2.6 and 3.2?
Parts listings show a variety of auto gear boxes part numbers for the Omegas, identified only by ident numbers, not engine size.
I wondered if anyone had information on this - are the 2.6 and 3.2 the same gearbox; any difference being in the torque converter with the final ratios transmitted to the rear wheels being determined by the diff, or are the gearbox ratios different?
In short, can a gearbox from a 2.6 be fitted in a 3.2, or am I looking at further problems? Reprogramming the gearbox ECU for example? 
Or would it be wise to find and fit a gearbox with the same ident number?
Anyone with experience of this or the technical info that could shed any light would be greatly appreciated.
John

Omega General Help / Auto gearbox judder / shudder

« on: 26 August 2012, 00:19:27 »

This is my first post on this forum, although I have been an interested reader for sometime! Just wondered if anyone could shed any light on what I think is an auto gearbox fault.
I have owned Omegas for the last 8 years; currently I own two 3.2 Elites, a 2001 saloon, and a 2003 estate.
The estate has developed a problem which I believe is the auto gearbox. The symptons are quite straight forward - when warm, and slowing down at slow speed for a junction / roundabout etc and the gearbox drops down to second gear, as you begin to accelerate, there is a judder / shudder from the transmission for a couple of seconds. It's similar to an electrical misfire, but also similar to clutch judder from a manual gearbox. It drives very well at normal road speeds, changes up the box smoothly, but has this annoying judder / shudder which is only apparant at slow speeds as the box has changed down and I begin to accelerate gently. It isn't as obvious if I accelerate hard at this point. Whether its connected, or just coincidence, but the problem began to show itself following a failed engine ecu, when the vehicle was recovered, and was towed for approx. 5 miles. The tow was by a dolly with the rear wheels on the road, and the speed was kept under 50 mph. The car has only done 57,000 miles. As far as I'm aware, the gearbox oil is the original from new, and I haven't checked its level or condition of the oil at this point. Any suggestions as this is spoiling an otherwise superb car!
