Has something to do with your OBD II serial port. If everything is communicating, I would not be surprised if it is just something that came along with the tune. If you are that concerned, contact your tuner and ask him/her about it. No CEL, correct?

Nope no cel but i have a airbag light that i always had.

Air bag lights are legit. Get it fixed. Vag Com may be able to tell you which components is the issue, because it does it when it comes to the ABS. Scan your car and see which components it says it causing the issue and get it fixed. More like likely a wiring issue (ie frayed wires, loose wire, or connector simply need to be cleaned with electrical parts cleaner).
