Omega General Help / Re: Check Automatic Gearbox - Warning light

« on: 06 November 2010, 19:28:55 »

I suspect a paperclip / pedal test for gearbox codes would help here

Gearbox codes can ONLY be read by a reader, and not all readers at that. I have the maxscan and it will NOT read gearbox codes.

I "think" that Opelscan and Tech2 are the only ones that read gearbox codes RELIABLY



and the 2.2 can't use the paperclip or pedal trick anyway .. even for engine codes 

Ooops... sorry for giving out slightly duff info there. I was under the impression that the gearbox could be read in this manner....  Every day is a school day

Omega General Help / TD Cooling

« on: 21 October 2010, 18:46:44 »

Do diesel omegas generally run cold ish... Mine doesn't generally even reach 80ēC on the gauge.

I know the gauge can be a bit inaccurate, but that does seem low... oh and I have no fan fitted

Omega General Help / Re: 5 speed auto gearbox in Omega

« on: 19 October 2010, 20:39:36 »

Only the Y25DT engine ever had the 5 speed, anything else is a modification.  Its fair to assume, then, that only Y25DT maps are available for it.

From memory (only seen pics), it goes something like 234DNRP or 134DNRP

Picture says a 1000 words and all that....

Omega General Help / Re: Help _ Strange auto Gearbox behaviour / revving?

« on: 19 October 2010, 07:47:23 »

This sadly is similar to the woes i had with my box... this resulted in the gearbox oil boiling itself and recovery by "AA".

I suspect that mixing D II with III will have been a really bad idea, and certainly all the autoboxes (Senator and Omega) I have had anything to do with recomend D III.

In the long run I would be looking for a replacement box

and after 9 hours of complete rewiring....... it appears to have worked. The thing runs properly, changes gear as it should etc. I still have a little tidying to do and connect one wire, CC I think (X2-9 black/yellow) but that's about it. The ebay bargain certainly proved it's worth and now for all intents I have a X25DT.

Just got to blink test it to see if code 64 has vanished and monitor fuel consumption

Next job.... fit the diff from the TD so the revs are a bit more sensible.

Just an update, I have acquired the e bay bargain to help with the sorting of this problem. (Thanks to the AA for rescuing me when the gearbox exploded on the A1...)

Plan of attack

1) remove engine harness from donor car and fit to mine, including ECU and MAF sensor, hopefully this will sort any strange wiring issues when I fit the gearbox ECU.

Then if necessary, rewire from the engine bay to the Gearbox ECU and fly by wire.

2) If that fails and I have as suggested skipped a tooth an knocked the timing out, then swap the engines over

3)... If all else fails then I give up and buy a bike...

In A  strange way Rich thats good news!! at least now you know it isnt anything to do with timing chains or fuel pumps etc?if its just a wiring interface problem it should be sortable with patience? would it be worth paying a visit to your nearest tech2 holder within OOF to see exactly what the car is sayin?

nice lttle purchase there!!!!

That was my thoughts, and I will fix it... Was going to visit Mark tonight, but in light of the purchase I'm going to hang on until I've had a bit more of a fiddle about with it.

The one I have bought will have a different engine ECU i'm guessing as it's likely to be a X25TD so will have MAF sensor, but it will have a shed load of spares that will come in handy, not least a correct gearbox ECU. It's actually built later than mine according to EPC but registered earlier...

.... and this gets dafter...

just had the autobox fault out (limp home mode) and when like this the engine is almost happy, I say almost as it has a chug or two to itself before it settles at idle (even in P/N)

This leads me to believe that I have a problem between the autobox ECU and the engine ECU to sort out.

and a recent ebay purchase >>> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=140460650580&ssPageName=STRK:MEWAX:IT might help with this    just got to sort out getting it home

Me again... 

Still haven't manage to locate the component called Y20 which has a couple of wires (Red/White & White) coming out of it.

But on another note Omegatoy mentioned I may have knocked the timing out, is there a simple way to check this ? Haynes is a bit rubbish for the TD.

stand to be corrected,
 the timing is set by coloured links on the timing chain dont know of any other way of setting it except by someone who may have a dti gauge and the bosch equipment?

Which does mean stripping the front of the engine down then ??    bugger  Still here's hoping it isn't that and I really have done something stooopid

Anyone know where Y20 (injection regulation) lives ??

It is on the bottom of the pump(the one inside the engine bay)it may be located inside the pump its self

Is this the one that on another post somewhere, someone has called it "Fuel Quantity Sensor" ?? erm which sort of brings this post full circle...

Well you need to get it connected up fully first so we can rule that bit out 

Yep, think i'll go through the wiring again with a fine tooth comb, I thought I had snagged everything, but it's been nothing less that a nightmare trying to do this bit and it's easy to think because you have a wire the right colour at pin 50 and pin 40, i've not really thought if they are connected together at any point...

I'll report back...

Have you also connected
ECU        Autobox
Pin 40 to Pin 38
Pin 43 to Pin 26
Pin 50 to Pin 40 (I think, print is not clear)

43 to 24 i have, but now i'm not too sure about 50 to 40, (X2-2) GN. I have also spotted that it goes to TC which I completely ignored for the time being 

And that might well be for a speed signal.....(of course it might not as well, it could be the power off signal)

Goes to DZM (instruments), but i don't have that bit of the wiring with me at work so can't remember where it connects.
