No.....hes near me....I am in South Nottingham and could have a look at the live data and do a few tests......

Oops, was a bit tired, read Notts as Northants

[baldeagle]

The Vauxhall garage have carried out further checks on my Omega 2.2 petrol auto and the technician is convinced that the ECU is faulty. He suspects that the air mass flow meter needs replacing also ( at a cost of £87) but won't be certain until the ECU is replaced.I suggested that the flow meter be replaced first  but they insisted that the ECU was the problem.

Contact MarksDTM, let him run his TechII over it before you spend anymore money.

Thanks again for the advice

Sounds like someone who has run out of ideas to me. A visit to Mark required.

Just to say that I have been a member of this forum from it's early conception a year and a half ago, and before that another year on a different Vx forum. I must have seen posts from hundreds if not thousands of Omega owners regarding various problems with the cars. I have never ever seen one that was down to a faulty ECU.... this is not to say that ECUs don't go wrong, but as said it is very very rare. I would try to get to one of the forum members with Tech-II and forget about Vx dealer.

I agree, I have yet to see an Engine ECU fault (that may have changed - I'll put up a post in a while).  Most dealers say ECU failure because they simply don't know what to try next.

My Omega CD 2.2 petrol auto is back home on the driveway and I have the Vauxhall "Technician's" report detailing the diagnostic checks which cost £180 but I decided against paying the £977 for a new ECU.So far the engine is starting and running normally but the emmissions warning light is still 'on' continually.For what it's worth this is the report
"Emmission light on + misfire. Vehicle running + cutting out on drive into workshop. Carried out Tech test, several trouble codes stored, all not present, cleared codes and ran vehicle to see if any specific code would re-occur. No more codes came up. After running engine for a while noticed that the exhaust was glowing near the cat, suspect that the exhaust could be blocked, allowed to cool down then disconnected exhaust from behind cat. Still running poorly so mid and rear exhaust OK. Removed O2 sensor from before cat, still running poorly so cat seems OK. Exhaust must be glowing due to overfueling and burning fuel in cat, require more time to check into fault.
Reconnected all of exhaust, cleared codes and ran engine , trouble code P1555 was present, will require ECU update before investigating any further. Updated ECU, fault code now cleared, still running poorly but not backfiring anymore, checked throttle body, requires cleaning out. Cleaned out throttle body and top breather pipe, still running poorly but with no trouble codes stored. Will have to work through checking procedures to code that was stored previously. Checking procedures asked to check for blockages and for leaks on intake pipes. Breathers and throttle body already cleaned and checked. Next step is to check programming, ECU has already been reprogrammed. Checking procedures recognise faulty ECU, however code is not present at the moment"
The sales invoice stated that the valve timing was also checked but this does not appear in the "technician's" report.
PS thanks again guys for all your replies, I need to contact MarkDTM to arrange for further checks and 2nd opinion.
Regards and Happy New Year, Baldeagle

if any of you guys suspect anECU on any car try ATP,products in hednesford staffs(they have a web site) what these guys dont know about ECUs isnt worth knowing! they will check one out for you while you wait 1hr aprox if they know your coming or send by post, cost if iremember is very reasonable. you can always talk a problem thru with one of the tech guys.i understand they also write or rewrite ecu progs for some car makers.

[baldeagle]

If the ECU turns out to be faulty does anyone know what the likely replacement cost will be at trade price?

[Marks DTM Calib]

You dont replace them......you get them checked and reconditioned by the likes of Peacock and Purvey in Nottingham.....costs about 250 ish tops.

Or get a second hand one for much less.

[baldeagle]

I'm planning to remove the engine ECU and take it to a specialist for testing and, if necessary, repair.. I understand that the ECU is located in the engine bay next to the battery, are there any special precautions to take when removing/refixing?

If that was written by a Vauxhall Technician, then I am a monkeys uncle! Without the ECU update (which I doubt will help in the slightest) I could have done most those diagnostics and come to the same conclusions for you in less than an hour!

You really need to go and see Mark, I recommend viewing the live data with the engine running, to see if anything seems off the Mark...
