Omega General Help / Re: Won’t take much throttle & misfires – ECU?

« on: 15 July 2021, 20:42:48 »

Thanks guys but unfortunately I don’t have the codes, I’ll speak to the garage tomorrow and see if they kept a record of them. If not I’ll have to get somebody to scan the codes again – but, thinking about it, it would make sense to have an Omega expert do it and fix the problem for me.
I seem to remember we had such a fellow in the Northampton area, but I can’t remember his name. Does anyone remember and is he still around?

Omega General Help / Won’t take much throttle & misfires – ECU?

« on: 14 July 2021, 17:10:58 »

I have a problem on my 2002 2.6 CDX Estate – if I use more than half throttle it starts to lurch as it cuts out, comes back in, cuts out again, until I lift off the throttle and it runs OK again. If I don’t lift off within a few seconds it suffers a sudden loss of power as it goes into limp mode. If that happens I’ll pull in and switch off for a minute or two and it restarts again.

Once you’ve gradually got it up to speed it’ll maintain motorway speeds and the mpg hasn’t deteriorated. The fault is long-standing and not intermittent.

I had it into my local garage last year but they couldn’t get to the bottom of it and said it was probably the ECU.

Additionally it’s now started missing at tickover up to 2,500rpm and the engine management light is permanently on.

I’ve read on here a number of times over the years that it’s hardly ever the ECU that’s the problem, but that garages often say it’s the ECU because they can’t figure out what else it could be. So, could it be the ECU? If not, then what else could it be?

Thanks for the input, chaps. I got a used one from Nigel, fitted it today and everything works as it should again.

I'll test the one on the breaker I've just obtained, if it's ok it'll go in the parts for sale section

How do you tell if a unit is fully functional – is there a way of measuring its continuity/resistance with a multimeter?

. . . Quite a challenging position required for replacing it though...

Phew, you're not kidding! Upside-down in a footwell with restricted access and visibility is not my idea of fun.

Omega Electrical and Audio Help / Blower speed controller/resistor - new or s/h?

« on: 25 August 2016, 20:57:19 »

Hi guys, I have an '02 CDX Estate 2.6 – I was looking on eBay for a s/h replacement blower fan resistor ("hedgehog") and found a number of vendors selling brand new ones for around £20. Example here: http://preview.tinyurl.com/z4ynvvv

Has anyone had any experience of using these cheap ones or would it be better to get a known-working used one?

Thanks,
Chris

Omega Electrical and Audio Help / Re: Door mirror not moving left/right axis

« on: 24 October 2007, 12:46:15 »

Yes, the passenger side is OK. I'll start outside with the mirror and work my way in to the interior. Are there two motors per mirror or just one?

Omega Electrical and Audio Help / Door mirror not moving left/right axis

« on: 23 October 2007, 16:22:41 »

I’m having a problem with the driver-side door mirror – the electrically operated left/right adjustment has stopped working. No motor noise at all, just dead.

The up/down movement still works just fine.

There’s no evidence of a physical jam-up as I can move the mirror on its left/right axis with my fingers.

Can anyone suggest a logical sequence of events to investigate & rectify this?

Many thanks.

Thanks for quick and knowledgeable replies. If the ABS unit does fail, will the brakes still work properly (apart from ABS unit)?

Omega General Help / Multiple warning lights & speedo goes dead

« on: 01 July 2011, 20:36:58 »

A weird and disconcerting thing happened today. Doing 70mph and the ABS and traction control lights came on and the speedo needle fell to zero!

It stayed like this for about 5 miles until I came to a halt, then everything worked OK, but by the time I parked-up half-a-mile later the error condition had returned.

I returned to the car two hours later, started engine and all was back to normal*. By the time I'd got out of the car park the warning lights were back on along with dead speedo.

Throughout this worrying intermittency the braking and engine performance seemed unaffected.

*I should say at this stage that "normal" has lately been with the orange 'engine' light showing. My usual mechanics say this is a 'cat error' caused by a knackered No. 6 cylinder not burning the mixture efficiently.


2.6 CD Omega estate with 182K miles.

Any idea what this problem might be? And what's the likelihood of it causing a breakdown as we've a long journey to do this weekend?

Thanks for any advice you might be able to share.

Omega General Help / Any aircon specialists on forum/recommended?

« on: 10 August 2009, 22:39:04 »

About a year ago I had the aircon system checked for leaks and regassed on my 2001 Omega 2.6 Estate CDX. It improved it a bit but it would only ever get cool, never properly cold. The servo reset procedure made no difference.

Are there any aircon specialists on the forum who could fix it for me, or perhaps recommend a trustworthy place within an hour or two's drive of Watford/Hemel area?

Thanks for reading.

Rgds,
Chris
