PLEASE HELP… At my wits end, My VE is cutting out and dash board is going crazy

[dippa24]

My VE commodore 2011 keeps cutting out while driving, the dash board flickers, the engine light comes on and once I stop pull the key out, open the door and close it again it starts again I have had my alternator replaced, batteries replaced, new key provided, auto electrician check for faults and has been serviced but no-one can find anything wrong with it but it’s not normal for a car to cut out while driving so there is most definitely is a problem somewhere, PLEASE HELP! Has anyone else experienced this problem?? I am at my wits end with this and is costing me a fortune in parts and labour.

Thankyou in advance

You need a diagnostic specialist. Someone who is not a mechanic or auto sparky. A diagnostics tech. They specialise in this stuff.

Get in touch with the diagnostics tech association called TAT. They can point you to one of their members near you.
https://www.tat.net.au/contact-us.html

Then you get your issue sorted and it will be done in a methodical data gathering, evidenced based solution. Not a guess.

These things can not be resolved by tweaking the thingy or replacing the what’s-it. Circuits and sensors will need to be tested and that can only be done with proper scan tools, oscilloscopes and a heap of training and industry support.

You don't need some fancy science lab to solve this issue.
What you need is a good auto electrician.
There are some that fit accessories, then there are some that diagnose stuff properly.
What you need is to tell us where you live then someone might be able to recommend a place in that area that actually knows how to diagnose.

Those fancy places Fu is talking about are basically auto electricians anyway. Like the guy that does repco training nights, he used to be an auto electrician and then started a company called Coda that made automotive oscilloscopes.

I used to work with two auto electricians that both owned there own oscilloscopes and used to diagnose stuf like this all the time.

I still remember this other auto electrician I used to work with, it was a Rav 4 and it had similar issues, turned out to be water leaking on the ECU from the windscreen as the windscreen guy left a gap in the sealant. The ECU had corrosion on it and he cleaned it up sealed the hole and it ran fine.

If you are in Canberra I can recommend a place

But also that TAT place would be a good place to start as Fu mentioned.

Unfortunately the auto sparkie and mechanical industries are being left behind in having relative skills in solving diagnostics issues.

This forum is a prime example and responses like that above are part of why no one can find solutions to these problems. This forum is almost exclusively filled with people who have been to endless places and only experienced parts swapping and guess work.

There is a total lack of skill to do diagnostics on cars that are 20 years old (or so) and yet we are going to electric vehicles with management systems like a fighter jet. The industry is totally unskilled for such progressions. It’s out dated.

If it wasn’t like that, no one would need to post because they have been to see a workshop that could easily sort it.

This is the entire reason TAT was formed. It is spoken of a lot in the diagnostic industry which really is in its infancy as a specialty area of the automotive industry globally.

You can piss about guessing or take the car to a workshop that uses scopes and bidirectional scanners to correctly sort a problem.

So far in Australia, TAT is the only organised group specialising in the diagnostic field. They bump info off each other and employ correct methods of diagnosing vehicles with evidence based data. They create their own tech bulletins independent of manufacturers.

If someone says something needs replacing, ask them what the evidence is. What data was gathered to support it. You know how many can actually do that? Not many.

I have three places in Perth I take my car to when I’m time poor or out of my depth. Depending on the issue depends on who it goes to. All are very good in their areas of specialty.

Overall, automotive manufacture and tech is moving at light speed compared to the skills being learnt at TAFE’s around Australia (and internationally).

We can’t keep taking our cars to the local workshops. We have to seek that specialised diagnostic skill. We have to seek out those who have continually up skilled rather than sat on their qualification for decades.

This car is going bonkers and OP needs to get it looked at by some skill, not guesses made with test lights and uno cards.
