How to tell what chip is in the car?

[cmore]

I just bought an '03 RS6 with a bunch of upgrades and 30k miles. I know it has an O.CT chip, but I don't know what stage it has.

The engine upgrades include a O.CT chip, transmission program, Milltek downpipes, high flow cats, cat back exhaust, K&N, hyperflow DVs.

Is there any way of finding out or maybe even with a VAGCOM?

Thanks,
Chris

i tried to get a "stasge 2" chip and was told it wasn't available. So most likely it's stage 1 chipset. If it runs 2000 MB on vagcom then ou're at stage 1. log block 115 on vagcom.
