Hi Guys. First off I know there have been other threads about this issue, but having looked through those I can't find one that sounds exactly the same as my problem. So about 8 - 9 months back I got an ESP OFF light and Check Engine light, which both disappeared before getting the car into Holden to check. they said they found absent codes in the sytem, and explained that as meaning the codes were logged, but no longer relevant as everything tested out as fine. So it's been fine since then til about 4 weeks ago, driving home from work on a Friday I got en ESP OFF warning, but the car was driving fine so I continued towards home. A few hundred metres from home pulled up at the lights, got CHECK ENGINE & SAFETY MODE ACTIVE warnings, loss of power etc. Pulled off to the side of the road, let it sit for a while, got it restarted and running ok again so got it home and into the mechanic the next day. After a couple days he got back to me, said it had a bunch of codes which he cleared, but kept getting a low voltage code and a MAF circuit code. So he replaced the battery and cleaned the air intake / throttle body assembly, everything tested ok, it ran fine for 1 day, then I got the ESP light again. Took it back, fault code was for the MAF circuit again, and he was also getting an open audio circuit code which he thought might be backfeeding and triggering other errors. He was reluctant to put in a new MAF sensor without confirming it was the problem, so got hold of a loan one and road tested with that in, was all ok, put a new one in, roadtested, all ok. Took the car home, drove it a couple times that day, no problems, next day i get an ESP light again. Take it back again, still getting a MAF code and Audio code. After consulting with a couple other tech's, they all agreed it was highly likely the audio problem was causing the issue. So I took it to Albert's, turned out the original guy that installed my sound gear has done a very dodgy job. The car spent the day in Albert's getting that all sorted, took it back to the mechanic on the Saturday, he cleared the existing codes and ran a full scan, got no more errors at all. Drove my car all weekend with no problems, starting to get confident that it's finally fixed. Then this morning, head off to work and get 500 metres up the road and the ESP OFF light comes on again. So at this stage both myself and my mechanic are at a bit of a loss, so i'm wondering if anyone has any further ideas or has had similar problems? I have now spent $1600 on not fixing the problem and would really like to get it sorted out. As much as I like and trust my mechanic, and he's been very forthright with me, and in fact charged me a lot less labour than he has actually spent on my car, maybe I just need to take it to Holden? Oh and for info purposes, it's a 2006 VE SV6, had timing chains done 14 months ago, up to date with servicing etc.

Possibly a broken rear abs loom - sounds like the same prob my partner had with her omega - $50 approx from the local auto parts store (genuine Holden)

ABS circuit issues wont throw MAF codes.

What is the actual code number, symptom code and descriptor?

Not sure of the code number, will ask him tomorrow. The info on the scan tool said CANBUS invalid data, and MAF circuit error, I think. Will check tomorrow

ESP off is a suspension issue, stability control system, likely associated with ABS, as hinted above, looking at audio or MAF sensor is just a wild goose chase

Actually engine issues will disable ESP so an engine light and ESP off warning could be the result of a MAF fault.

Ok....so after much testing and fiddling by my mechanic's fuel injection specialist, they think they have narrowed it down to the issue described in this thread.

https://forums.justcommodores.com.au/threads/any-options-engine-parts-other-than-holden.201582

This upgrade was never done on my car, and has probably never been a problem until a software upgrade done with servicing.

So, he's ordered the kit to bypass the VIM Amplifier and connect the valve directly to the ECM, he said its a connecter, some wiring and bridging 2 pins on the ECM? So hopefully this will fix the issue.

VIM Amp will only cause issues if the ECM software is updated and it will only throw a P2008 Intake Manifold Runner Control Solenoid Circuit Malfunction.

Dealerships wont update ECM software as part of the service, there needs to be an issue for that to happen.

Vehicles with build dates after Feb 2007 already have the VIM Amp deleted.

Hmmm...ok....this is getting more interesting. Would the dealership have done a software upgrade when they replaced the timing chains (April 2012) And if so, would the problem come up straight away, or possibly take some time? Never had any trouble at all til a few months after the timing chains were done, and after Holden cleared the codes it was fine for 6-8 months til it started happening again. Still scratching my head at this stage. Maybe the guy has updated the software trying to get rid of the MAF problem and it's triggered this other issue, I will investigate further on Monday. At this point I just want the damn thing fixed :(
