ABS logging

[newtoS4]

Hi guys,
I have a strange fault where my ESP light comes on at aroung 5000rpm in third gear. And at other times too.
I have the full VAGCOM kit and there are no fault codes logged.
So..
I tried to record wheel speed etc while driving. (Using a passanger I hasten to add.) But connection to the ABS controller fails, it was fine sat still and not logging.
Any ideas?
Thanks

The ABS control modules usually drop connections between 20-60 km/h for security reasons. This is absolutely normal and you'll experience that with all models and diagnostic tools.

Even though you have no codes, would you mind posting a complete Auto-Scan from the vehicle in question and also post year, make, model and very important ALL modifications you made.

Auto scan attached....

Car is unmodified, or at least that is what I am told.

Also I have a log file with lots of engine detail boost MAF etc when the fault happens but can see no problems.

I can send this to anyone by mail if they can help.
