Hi guys,

I am using CMD flash tool in slave mode. Costumer often ask me wheter chiptuning can be detected by OEM.

What do you think. Is chiptuning after using the "100% back to stock"-button still detectable by OEM?

Thank you very much.

Kind regards
Christian

If the TD1 flag is allready active on the VAG servers, than you can never delete it. Even not when you use the 100% back to stock button.

When you use the 100% button BEFORE the car connects with VAG-server, than no TD-flag will be rased

Ok thank you.

But when will it connect to server the first time? If i'am going to buy a new car from a dealer the car maybe is connected allready before the delivery? Don't know.

the flash counter show the oem that the car has been flashed x times

you need spiderboot inside the ecu to avoid the counter increases
