    No one to look at it near me unfortunately. I disconnected the battery and it was fine for about 40km then just the EPC light came back on.

    I plan on taking the car to a specialist in Sydney later in the year for a carbon clean and a full check over so will sort it out then.

    Have you googled? Other people have had the same issue and it has pointed to the throttle body.

    Got the car back yesterday and this was the issue.

    The throttle body was dirty with carbon deposits and was cleaned and now it is sorted.

    The problem is the bill came to $1016 and most of that was labour investigating something not related, they pulled the wrong ECU (Slave) and did all of their testing on that and were getting errors. I don't pretend to understand what or why they were doing that but it lead them to believe there was a problem with the harness.

    I am going to call soon and see why this happened, as unfortunately the guy i was dealing with yesterday went home early so another service officer had to take over and she wasn't up to date on what had gone on.

    Sounds like an 'Audi tech guru'.

    If it makes you feel better, I had a stalling issue on my 100 series turbo diesel LandCruiser a few years back. After $7k in investigations at Toyota and a diesel specialist, which included $5k to replace the fuel injector pump (it's a very complicated mechanical/electrical unit nearly the size of a 4cyl engine), it turned out to be a blocked breather hose on the fuel cap. A $5 fix.

    To their credit they didn't charge me for their initial wrong investigation, charged for 5 hours labour instead of 11 hours.

    He did actually find the problem which I have since discovered had not been found before as it went in for a similar issue down in Melbourne a few years back. The throttle body was cleaned but the underlying cause was not fixed.

    The throttle body was reading 3.4v on the earth pin, they managed to locate the 2 wires there were damaged and causing the short and fixed them. They then cleaned the throttle body and the errors went away and the voltage returned to approximately 5 volts.

    At least it is sorted, better than having the engine out for no reason and back to square 1.

    Yeah, pleased it is all done. 5 hours labour isn't too bad I guess.

    I'd be happy with that. Very difficult to diagnose and locate, people get wise after the event but it's headless chicken mode when there is absolutely no leads to the fault and it just takes time. This guy seems to be on the ball so well worth remembering him for other work.

    Completely agree with Ichy and we share demon's relief.
    Unfortunately we are inadvertently developing a large number of auto technicians to whom the answer to almost everything is digital in nature; if it cannot be found via OBDI/VCDS then they are stumped.
    Whilst understandable it is rewarding to stumble upon folk who are able and willing to invest time and intelligence to ultimately find the problem and provide a solution, digital or not.

    Yeah I have to say the tech guys at Gold Coast Audi are very good, funnily enough I went through the receipts of all the work done on the car and a few years ago another Audi dealership that shall remain nameless failed to identify the issue which would appear to be related to this one. They also reported irregularities in the ECU and actually asked the previous owner if the car had been tuned.

    So I am happy the short has been fixed and the throttle body cleaned.

    Not sure if it is standard now at all dealerships however the GC one now has an Audi OEM walnut shell blaster. Prior to that the guy I know and the one that still works there made their own and used that to clean peoples cars.

    A full carbon clean with walnut shells for the valves and chemical cleaning for the manifold now only takes 6-7 hours there and they charge between $1100-$1400 for the work.

    Couldn't agree more, and thank you.

    I see you were an SQ5 TDI owner too, I love mine.

    Agree, but it doesn't help when they pulled the plug on the wrong ECU. I have a vast amount of complex fault finding experience on machines far more complex than our cars but do have sympathy for the guys involved because fault finding of any degree can lead you down the wrong path at the best of times.
