Engine management light
« on: 14 January 2007, 11:38:38 »
On my '97 2.5 V6 auto...

Engine management light came on.  Made it to work - no problems.

Started back from work (light still on, again no problems).  She drove all the way home (approx. 25 miles) without hiccup.

Any ideas what it could be?  Whatever it is that's causing the fault, it doesn't seem to be that serious as it's not impeding on the performance of the car at all.

Just get vauxhall to do a diagnostics??

Thanks,
Lachleaves.

Try and read out the fault codes yourself. This involves bridging a couple of terminals in the diagnostic connector in the fuse box (if its a 16 pin connector then its terminals 5 and 6), turning on the ignition, and reading out the number of flashes on the SD lamp. If you search for  'omega fault codes'  this should give you enough info to do this. The codes should point you as to what is complaining. No need to pay VX lots of dosh at this stage!. :)

Pins 4 and 6 or pins 5 and 6. Makes no difference ;)

Is it a 2.5 or 2.6? If 2.5, do paperclip test. If 2.6 you cannot do paperclip test, but can you describe what lights look like...

Thanks everybody.

I'll give it a go.  (it's a 2.5 by the way, not a 2.6)

i did it - and it worked... well sort of!

with engine running, it was clear after 12, 129 then 132.

what's the 129 code??

I've checked the 'topbuzz' website - there's no code 129 there (under bosch motronic).

132 comes up as 'exhaust gas recirculation (EGR) valve - incorrect signal'.

does this sound right so far?

don't suppose anyone can tell me what it means?!

many thanks thus far,

About 200 quid at a Vx dealer to change EGR & car may start to stall when slowing at  junctions before it fails.  Hope it's not faulty  :y

what's the expensive part of the job - the replacement valve or the labour??

and does anyone know what the code '129' is?  (it's not on the fault website)

what a predicament - i've only just got it!  ... and now i'm facing a £200 bill!  (don't suppose the diagnosis could be wrong?  a blip?)

...and anyway could the fault re-occur (nothing to do with having a recent exhaust + cats?)

many thanks anyway,
lachleaves

you know you said 200 quid to get EGR replaced and it may start to stall...?

did you mean that despite paying VX to replace it - IT COULD STILL START TO STALL, STILL BE FAULTY??

just done a quick search - loads of members keep mentioning this EGR valve and a blowing exhaust.

mine's blowing a bit?  (could be a cause for the failure??)

where the hell is this EGR?  how do i get at it - as some members have mentioned removing it and cleaning it!
