Title: ruff idle then cuts outs, help please
Post by: paul.77 on 02 November 2008, 16:18:53
This may be a bit long winded but heres what happened.
1 abs tc lights have been coming on and off for a couple of weeks so decided to remove the ecu today ready for repair.
 2 last night car started but was very running ruff on the way to the shops about a mile away but was fine on the way back. It would not go above 20 mph and was very ruff on idle.
3 removed abs ecu today and then tried to move the car. it started but the just died after shaking it's self to bits.it just does this now every time i try to start it.
done the pedal trick and this is what i got
10-1-7-3
10-1-7-9
10-6-3-8
2-1-10-7
10-5-10-7
10-5-6-7
1-7-4
thats how the lights flashed not to sure how to interpreted them
any help will be greatly appreciated  thanks paul

I don't know the codes off the top of my head but I suspect they're reporting random missfires...

Are the coil packs/plugs ok? Any oil in plug wells? Any major air leaks?

have a look at link below. But i would recommend double tripple checking the codes are correct before you dive in. Its easy to miss count as you may have noticed.

According to a couple of google searches your fault codes are...

u2108 CAN-Bus no Communication with ABS/TC
p1612 Immobiliser signal error
P0500 Vehicle Speed Sensor Circuit

First one points to your ABS ecu which you know about.
I reckon changing your crank sensor will sort the rest.

Look here http://www.omegaowners.com/forum/YaBB.pl?num=1189022687 Seems like you have ABS/TC issues and immobiliser non-recognition

crank sensor changed and it still will not start. it turns over but does not fire as before.codes are still the same.forgot to say he said there was a oil sensor leaking so he replaced it?

Does the EML flash when you try to start the car?

I dont know .the car is still at the gararge he's now talking ecu problem, he says it smells funny, like easy start? never heard of the stuff so i don't know what he means.

if the ignition was turned on with the abs ecu removed then that would explane the any codes related to it, and i dont believe that would stop the car starting.
The immobiliser seems to be the relevent issue. This is said to cause a dash light to flash when trying to start, hence the question above. Hth.
