OK that's good to eliminate the ICE
So what is the latest sit rep?

Is it a complete non starter as in
Car won't start.

or does it start and then die as in
Car started with only the air bag warning again.
Put it back together and got the same 30 seconds before the engine cut out

Do all those exact same displayed fault errors come up after 27secs of ign ON?

It was and still is a non starter. Battery off over night allowed me to start it but after 30 seconds it stops and the previously mentioned errors pop up. This happens whether the engine is runing or just ignition on.

There is an ECU update for the 1.6 could this have anything to do with it?

I would like to formally thank you all for the recent wave of great advise so far, it really is appreciated, again a huge thank you to Shadeyman (Stu)

I would happily still take onboard any advise or solutions to get my beast back on the road.

I would also like to retract my original moan about the garage, on the day i towed it to Shadeyman's house i had an oppourtunity to speak to another salesman who took onboard my complaint and passed it to the sales manager, who called today to formally apologise and offer his services at the price quoted £50 in vat for diag, an offer i may take up sometime this week.

Again thank you all, special thanks to Stu once again.

No, definitely not

If you clear the fault codes, that will reset the ECU, the same as leaving battery disconnected overnight. Have you tried disconnecting the pre cat lambda and then ignition on to see what happens as that's recording a "fatal" error?

Ok, all CAN messages from ECU to BC have to go through the power steering node. Can you simply drop down the lower steering column surround and get to the two connectors there?

One will be the power connector A, the lower one here with just two fat wires (beware, it's a permanent live, check if you're getting a good earth from connector A through to power steering earth point C14) and the other connector B will be the 10pin CAN line connector. Some clean up there of the pins and remaking the connector B may restore the comms that are flaky between ECU and BC

I'm thinking that with an ECU failure then you should get ECU fault codes of PCM failure but you have CAN connection failure warnings and that's different

Removed the lower steering column cover, disconnected the battery, removed cleaned and checked connector A and B. Both looked good although B did feel a little looser, no where near as snug a fit as A. Car started, air bag failure, no other errors. Slowly increased the RPM up to 4,000 at which point the engine died. I noticed the rev counter stick at 4,000 for a second or two before dropping to zero and then the previous errors started to display on the dash. Total run time about 30 seconds again. Tried the same cleaning thing again twice, car didn't start. :(
 
I think with an ignition switch issue it would just turn off the engine with no fault codes or just keep running or not start at all

When it starts does it hold idle? Difficult to tell I know if it's only for 30secs but are you needing to pump the gas pedal to keep it alive? Dos tha gas pedal have any effect?

It's going to be very time consuming to analyse if it shuts down after 30secs every time and then takes ages to set it up again

Hmm never considered the ignition. I can do a test for you to see if mine does the same. Can anybody confirm if its detrimental or not to remove the key with the ignition still live to see if the engine eventually powers down?
 
I can :devil: Due to our infinite wisdom we unplugged the Head unit and split charge to sort a problem. It looks like we have accidently put the ignition splice on the accessory of the switch and god knows what on the Head Unit. Only ive driven the 100 odd miles home before noticing and didnt do the original wiring so dont know whats whats.

The outcome. No switch on the split charge but i can feed power to the ignition with switch on and take the key out of the car whilst its still running. Come to think of it i dont get many revs if i blip the accelerator. This may help Stu (y)
 
OK so Immob working
CAN lines working
Car starts but no control and can't hold idle rpm

That sounds more like Throttle Body or ECU to throttle body comms

Car starts only if left for 5 or 6 hours before starting. Will run great for about 30 seconds. Idle ok and throttle ok. Then engine stops regardless of RPM, tick over or redline it would stop.

It seems the longer its left the longer it will run for. Left it over night with battery connected this time. Started it dinner time and it ran for about 2 min before stopping. Engine temp had risen to the first mark before it stopped. When I turned the ignition off and back on the temp was zero, perhaps another symptom? :confused:

Might try and retrieve the error codes again this evening, see if anything has changed but not sure multiple starts and epic failures will do the car any good, may have a "knock on" effect and take out more systems?

I wouldn't hold your breath, its the same garage that couldn't connect the diagnostic machine to the ECU in the first place.

Change of plan, he's collecting it Saturday and taking it straight there, I only live about 300 yards away from the dealers.

I've printed out the error codes I managed to retrieve for him, lets hope they help.

You appear to have tried everything else, have you tried disconnecting and reconnecting the engine managemant ECU connector(s)?

Used to cure all manner of problems with older generation ECUs. Perhaps some contact cleaner while they're apart?
