History

I have a old Corsa C on a 52 plate. Its been off the road a good couple of years and I was going to scrap it. The car is mechanically and bodily sound but the engine ECU has problems on the lambda circuits and at the last assessment for emissions the carbon monoxide was too high. Last time I checked the lambda circuits I remember heater circuits faults and lambda switching high and low was poor. I did change the lambda sensors and it worked again but after driving a couple of hours the EML would come on. A fault code read pulled back the lambda circuits.

Getting to the point

I own TECH 2 but have not used it for years. Hopefully it still works! I can't remember but seem reasonably sure TECH 2 will not read security codes?

This being the case, what can I aquire that will let me do a reset and change the code from one ECU to another?

Thanks

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Have you got the card with the radio code and security code from past experience you might need that

Very unlikely given the age of the car and being past down the line.

If you have a log book you can still get them off your local Vauxhall dealer we got one for a 10 plate Astra van a couple of years ago

just a thought but back in the day the wiring would generally sh1t itself -typically after a shot oil pressure switch-which would let oil wick its way down the loom with lambda faults being one of the first stops on the journey and the crank sensor normally being the last stop on the line.you sure its the ecu?

Yeah I've done loads of testing with it over time with good advice from a member of Pico who's a master tech. He's very well respected and really knows his stuff. I changed the lambdas and the engine has no leaks and is actually a mint little engine. Apparently I'm told these ECUs are common for lambda circuit failures.

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

yeah,astra g had similar probs with the engine ecus.chip,transponder + ecu was kit bought a lot from the second hand guys back in the day with the corsas complicated by having to change the dash + bcm as well.kit used to be about £100(or as mine was bought from a mate who broke em 2 pints of suicider!)dont reckon theres many left to strip for bits now tho.the common faults were lambda/throttle body/pedal + egr.basically any fuelling fault meant the ecu cud be suspect and given its feedback voltages were generally what you were looking at to diagnose the damn things in the first place and it was telling porkies.....well it cud get interesting!
