For cars older than aprox. 2005, normally yes. For newer cars, no.

Hi LN-TAL, thanks for your reply. Greatly appreciated.
My Audi is a 2007, so perhaps not then.

Can anyone confirm this.?

But are you sure that VCDS does not give you the code you need ? Have you looked ? (or just assuming)

Hey mate.
I have moved the mouse pointer all over the screen, as I know it does reveal a code for some people, but no, in 01-Engine then 10- Adaptations it doesn't show me a code anywhere. Annoying.

Where else can I possibly get the security access code from. I'm desperate, lol

Unless Ross-Tech know it or another user has managed to figure out what it is then you may be out of luck. The main reason I said to post your complete Auto-Scan details in your other thread is because someone at RT can then potentially look up the security codes they already have documented for the particular controllers in your car.

I'm not sure if any of them are published in Erwin.

For a car as new as the 8P he's driving, VWAG's documentation is going to be all full of "Use Guided Fault Finding" or "Use Guided Functions". I'm confident there's a security access code that would allow his idle speed to be tweaked, but unless the guys in the white lab coats back in Germany decided there was a procedure in the factory's tools that needs it, it won't be anywhere to be found.

Well, there's an exception. Chip tuners often find these codes for ECUs in their travels.

Hey again guys.
I guess somebody must know it, if it does exist that is.
Any Chip Tuners/users that you guys know, that may know the code.?
I know you have the same engine code Uwe, have you never gone in search of it.?
Cheers,
Rob

What are you trying to do? Can you post an auto scan?

Hey Andy.
Hope you may be able to help me. Let me know what you think when you have had a look at the log.
Would be greatly appreciated.

Thanks Uwe for pointing Andy in the direction of my auto-log.
Most appreciated.
See if we can get anywhere with this :O)

Rob,

As said previously, altering the idle speed may just be masking your root cause. Quite often a fluctuating idle is caused by a tiny ring of carbon around the throttle body next to the butterfly plate. Try removing the TB and gently opening the butterfly; hold it open with a wooden peg then get in there with some carb cleaner and an old toothbrush.

The reason the carbon causes the fluctuation, is when at idle, the ECU will move the butterfly to its 'learned' position, which when learned would let a certain amount of air through. With carbon build up, the butterfly effectively closes on to this carbon and chokes the engine, the ECU spots the engine dying and rapidly opens the throttle, only for the cycle to repeat.

Hi Zenerdiode. That's a good suggestion.!
That may be something I can look into. Just wanted to make an adjustment to see whether it smooths idle out a bit, but you may be onto something with the TB. I'll look at how hard it is to do and then see if I have the correct tools to carry that out.
Many thanks,
Rob.

I'm not sure there is a possibility of of changing the idle via adaptation on this car. You probably should look into throttle body / MAF / vacuum leak issues. As far as obtaining a security code for this ECU, it is possible but you have to read EEPROM inside the ECU and calculate the PIN using a calculator, for example like this.

BR, Andy

Hey Andy.
Thanks for the info. Looks like it may be a bit beyond my capabilities, seems confusing unless it's actually pretty easy in reality.
I'll look into the other suggestions first and if I feel up for it, I'll maybe refer back to your link.
Many thanks for the help mate.
All the best,
Rob.
