[Nunziopower96]

Hi to everyone! i've a problem with my audi, i've had a little fron accident and the damage was:
the right headlight, the grille, the front bumper, the steering wheel airbag and a charger port sensor.
Now after 6 months and thousand of €, the mechanic (not AUDI) repaired all the car with all this broken parts, but, when he make a reset of the car with the ODB the car dont start.
He says that theres no errors in the car, but the error is in this video I make, the "etron read" advice blinking. now he told me that I have to take the car with the tow truck to the Audi dealership, but I wont spent other thousand of money I would try to resolve by myself,
thank you for aswers!

Based on your video, it looks like there is still something going on with the charge port sensor. It's almost as if there is a short circuit to that sensor causing the car to flicker out of "Ready" mode as if someone was constantly plugging and unplugging the car.

Try plugging in the car to see if you get the same issue on the dash. Plugged in, the car should NOT enter ready mode as a safety feature to keep you from driving away while still plugged in. If the car does the same where it keeps jumping between off and "ready", you can tell your mechanic to repair the switch correctly.

Good luck!

Hi icee! thank you for the answer! i've made a new video, with the car in charge there's a security message and the READY message does not appear. but I agree with you about some charging port issues, we've changed already this sensor in photo.
Another thing i noticed is that the car starts always in "EV mode", although I put on BATTERY HOLD mode.
Yesterday instead, when i made the first video, for a second, with charger not connected, the security message of charger connected appears for just a second, then disappears; so i'm agree with you about charging sensors, so I made a photo of the sensors.
Thank you so much for the help!!!

It's normal for our car to start up and drive off in EV mode until the battery is drained or you change the modes.

Something I noticed in your second video, right at the 35 second mark, it looks like the green charge status light blinks from green to red and back a few times. I thought it may have been when your car was unplugged. The Audi manual isn't too helpful here as it states, "If the 'red plug' indicator light stays on, there is a malfunction in the charging system. Have the problem corrected immediately by an authorized Audi Dealer."

I just checked how plugging and unplugging my car shows on the cluster display. The charge status plug icon changes from green to yellow for less than a second then displays the green EV car icon when I unplug the car. As soon as I plug the car back in, it shows the green plug icon again. There was no blinking red icon.

You may want to see if someone near you has a Ross-Tech VagCom cable or an OBDeleven dongle where you can take a look for any stored soft fault codes.

Keep us updated as to what you find out!

The OBDeleven bluetooth dongle works on apple and android phones and can be found here:

You don't need a paid plan or purchase any points up front if all you want to do is scan each of the car's control units. Before you buy anything, I recommend youtubing OBDeleven to see if the features and data is worth your hard earned money.

The Ross-Tech VCDS USB cable requires a computer to use and it geared more towards enthusiasts and mechanics. Its much more expensive too. I'm not sure which model cable supports our e-tron as I have the older version for my 2011 GTI.
