I don’t know much about cars but I’ve been telling my friend that I don’t remember any pink bits when I last put the OBD in.. I did research on ai and he still thinks I’m just being overly paranoid.

New things I noticed that he brushed off
* new beeping sound
* beeping sound coming from the driver side
* beeping sound stops when he walks away with the key
* max speed @ 50km started showing
* EPC light came on
*am I overly thinking things or is there like some sort of glue residue out of the obd holes
* there’s a loose item somewhere where I can hear it occasionally when driving
* battery drain in car

Also I’m aware that the original Audi wiring are wrapped in black? No? Correct me if I’m wrong

I’ve been looking at autel and foxwell I need a reader that can program a Ecu if I replace it and that could read Srs codes any suggestions please and thank you
