Yea, mine should be 427. I already found all the maps and limiters.

Omega General Help / Re: Omega 2.5TD 2000MY AR25 Gearbox issues
« on: 16 September 2011, 00:45:24 »
Well, I managed to overheat the box in the end, so it spilled some oil out of the breather system onto the exhaust.
The person behind me was probably not happy
I got an AR35 box coming in from the UK in a few days.
I hope the torque converter is okay.
We'll swap the box and then I guess it's time to read the ECU and find IQ, Boost, Smoke limiter, Torque limiter, Boost limiter, etc... and have a shot at tuning the thing.
Does anyone know if the facelift Omega with the X25DT engine has exactly the same ECU as when they came out in 1994? So MSA11?
If so, that'll be a cakewalk.

So it just died.
Now I get the same issue in each gear, even in first when I apply more than just a tiny bit of torque.
The box also jerks around going in and out of gear all the time.
When coming to a stop it also disengages for a moment then re-engages and the engine sound changes...
So I will be getting an AR35, but since I need the torque converter and bellhousing, could it be that my AR25 torque converter is dead?

OBDII doesn't really read gearbox properly.I fully agree, I did not want to imply that the software update will solve it.
It does sound hydromechanical, so keep eye out for AR35, as I know the TCM firmware update would not solve that sort of issue (but may help mask it slightly)
Will see, drove the car a lot today, and had it not crop up, I'll stay on the lookout for an AR35.

Being a TD, I suspected its just knackered
Solenoid faults tend to bring up telltale before the symptom is felt. Hydro-mechanical issues tend to light the telltale a second or 2 after the symptoms start.
I don't actually get the light lighting up in the dashboard and I also don't have any faults stored in the gearbox ECU, at least none that I could see using a OBD II scanner.
I ordered a Tech 2 china clone from the bay, will check with that.
Got the TCU software updated today - transmission feels much smoother all around, and so far have not been able to replicate the issue.
However, I suspect that it will still be present after lots of stop and go driving.
I will also check the fluid level...
Anyway, I agree, that probably the box is just worn out, so I will try and look for an AR35 box, but since the car is driveable just fine (if the problem occurs, just put it in "3"), I will not have it as top priority right now.
I doubt there is any point in getting the AR25 reconditioned, as 250nm is silly anyway on a 6 pot diesel, it should do 400nm with ease...
Anyway, I still have my UrS6 with 600nm and thankfully a manual box

I don't remember seeing any plastic bits.Quotedoes sound like it could be one of the solenoids..As Jimbob says, perhaps when you had the ATF change the small sump wasnt removed which is where the plastic bits would be I believe.
has the fluid change made any difference to the issue?
better or worse?
I presume there were no small bits of plastic in the sump when you did the change?
There was quite a bit of metal on the magnets, but I was told this was normal for a box which has never had the oil changed before...
I don't think the small sump was removed.

Did you have the engine running when you were refilling the autoboxWe filled it, then ran the engine, checked the level, then filled it again.

After the oil in the gearbox gets hot, fourth "slips". Or rather, it goes into first instead of fourth it seems.

Hello,
I have a 2.5TD with AR25 box.
There is an issue with the box once it warms up. Drives perfectly when cold though.
Fluid/filter change has been done three days ago.
It seems as if there is no fourth gear. If I run the box in "3", it operates as it should.
If I run it in "D" after some town driving, then when switching into fourth - be it from third or second, it goes "out of gear".
Basically when going 50kph (35mph), the car does not accelerate unless you rev it to about 3400 rpm. If you floor it at this point, the acceleration makes me think it's stuck in first.
If I rev it past the limiter, it changes into third gear with a strong jerk, and the box goes into limp mode (3rd gear only).
If I manually select "3", it goes into third gear, and can be driven normally.
There is no issue driving in "D" on the highway, overtaking etc.
Getting the software of the box upgraded, but I doubt that will do anything for me.
Does anyone know what the issue could be? 4th gear worn out? Some seals inside the box being weak and once the oil gets thinner with temperature not holding enough pressure to keep it in gear?
I haven't disassembled an autobox (yet). Friend of mine who did it for a living, said there is a disc (or drum, hard to translate) that wears out on these boxes, which enables fourth gear...

Yeah, mine does not have LEDS indeed.
Do you happen to know the part numbers for the switches/battery holder? Could try to see if Farnell has anything in stock.

Yea you were right.
There was Vcc on the other side as well.
It was the battery holder that was repaired badly before and the other leg had developed a crack as well.
I removed both legs and used some wire and lots of good old fashioned 60/40 solder, which should be more elastic than whatever the legs are made of.
Works fine now.

Omega General Help / Omega FL 2 button keyfob problem
« on: 18 August 2011, 21:46:32 »
Keyfob stopped working.
I looked inside and noticed that there is probably a small SMD resistor missing.
Since I only have one such keyfob atm, could someone open up theirs and measure the resistor? Or at least take a picture?
Here is the picture:
I circled the bit which I think is missing. Someone has repaired this thing before (the power supply connection), perhaps due to that the component came loose. Without that component there is no positive supply going to the board, so it can't work.
I don't want to just bridge the gap, because that might mess stuff up. Looks perfect for a 0603 resistor.
Even if what I wrote seems like chinese to you, but you are comfortable with replacing the battery in your keyfob, please open it, push the board out (press a button from the opposite side when open) and check if you have a bit in that red circle. If you do, please give the numbers off it...
Thank you.

Hi,
Because my 400hp UrS6 is undergoing an engine rebuild and I sold my Celica, I needed a cheap runaround (I'd post pictures, but the rules set are not letting me
)
I got a good offer for a FL Omega with the BMW 2.5 TD engine and autobox, I decided to go for it.
Obviously, since I paid fairly little for the car it's far from perfect, but I am taking care of it, as I do with all my cars
In the five days I've owned it:
* ATF change, A/T filter change + gaskets
* Engine oil change, Engine oil filter change
* Changed intercooler, old one was like swiss cheese
* Engine air filter
* Cabin air filter
* Tyres
* Getting the locks serviced and a second key made up. Driver's door lock is missing parts, so getting them from the breakers.
* Scheduled service on wednesday to fix all the issues in the suspension.
Car drives fine, a bit less power than I'm used to, and as I understand the AR25 box does not take kindly to increased torque. Need to look what type of ECU this car has (EDC15? the engine is not common rail) and perhaps slightly increase boost up top.
Coming back to electronics - I need to update the gearbox software as it tends to hunt around a bit more than I'd like sometimes...
That's it for now
