Hey guys, long story short the abs ecu has gone on my '01 73k mile 2.2 petrol estate :'(. After weighing it all up it seems that it would be cheaper to scrap the car and get a new one, as my mechanical skill is minimum to take the ecu out and re install. I've heard this problem only effects certain engines and years is this true? I want to get another Omega but a v6. Am I likely to run into the same issue with a v6?
-
First time I've seen an ABS ECU fail on a 2.2 :-\
On the up side (like many things with 2.2) its a doddle to access, it can clearly be seen and very easy to get o.
What makes you think it's failed?
-
The abs light is on and no speedo function. Plugged it into diagnostic and it couldn't read the abs ecu so been told its the ecu.
-
Yup, that sounds like it. For some reason only tended to see V6 ones go :-\
You can get them refurbished. Cost around £130 here: http://www.bba-reman.com/uk (http://www.bba-reman.com/uk)
Easy to access on 2.2, see no reason to scrap it based on that :)

Ok cool, is there an on line guide some where on how too remove it? Also is it the whole unit that needs to come of like this...

For V6, but you can see here: http://www.omegaowners.com/forum/index.php?topic=90627.0 (http://www.omegaowners.com/forum/index.php?topic=90627.0)

Mines just the 4pot will it be based on the same principal?
-
Should all be very similar :y
-
Ok cool, and is it the whole unit that needs changing or just the main electronic part (2nd link)
-
Just ECU. You don't want to be changing the modulator.
It *must* be the right one for your car. ie, part number match, AND be off same engine/gearbox combination Omega.
-
Just the electronic part :y plus wot e sed... mtf ::)
-
Ok cool ive found one for a '01 2.2 auto, doesn't say if its from an estate or not will it matter as mine is an estate.
-
Shouldn't matter if Estate or Saloon, what matters is same engine/gearbox as yours and same part no. as yours :y
-
I've ordered the part so fingers crossed I wont struggle to much when fitting it lol. Do you think it would be worth sending the old unit of to be re built as a back up?

Definitely, as the new one will most likely fail :y
-
ok will do lol.
-
And ECU Testing are cheaper than BBA.....and equaly as good (lifetime warranty to)
-
Yeah I saw them, only £100

I have always used ecutesting, and have no complaints. There is a much simpler way of changing the ECU than described in the guide. Malc p taught me it. I have used it several times.
Basically you remove the power steering reservoir and the battery, unclip the ABS pipes form the bulkhead, loosen the outside ABS mounting bolt, remove the inside bolt, free it from the heatshield, tilt up the ABS/ECU assembly to reveal all six screws holding ECU to ABS body, and undo them.
If you want more details, let me know.

Hi thanks for the info! If you could pm me with the details it would be greatly received :y

I will describe it on forum. I last did it on a 2 litre, but have done it on V6s as well. If unwise, Chris and Al will say so.
1. Unclip fuse box above battery, remove battery. On V6 you may choose to move harness from above battery to engine too.
2. Empty power steering fluid reservoir, detach PS reservoir, remove hoses, remove reservoir.
3. Unclip all brake hoses from from bulkhead clips; leave pipes attached to ABS unit.
4. Locate ABS harness and socket; locate the violet coloured locking slide at bottom of plug; insert long screwdriver in the slot at the outside end and pull outwards, wiggle plug a bit and disengage plug from socket.
5. Loosen nut on outside ABS mounting screw; remove nut from inside ABS mounting screw. Bend back heatshield from inner mounting screw, releasing it.
6. Grasp ABS unit and tilt front end upwards to reveal six screws holding ECU to ABS modulator body. Catch bottom mounting buffers if they fall out.
7. Remove the six screws holding ECU to modulator.
8. As you pull ECU off modulator, locate and unplug cable beneath it to motor.
9. Reassembly is reverse of dissembly.
-
The only thing I would add to that is to be extra careful not to strain the brake pipes, and make sure the block is well supported as you undo the torx screws :y
-
I just undo the plug,chop all the brake pipes,undo the fixings and yank them out. They never have to go back on the same car though. ;D
