High voltage charge fault

[Brad1995]

Has anyone had any charging issues where it doesn't work at motorway services?

 

Because I have.  I have an electric car which doesn't charge. Audi refuse to help and won't let me reject the car.

There's a lot of documented case of motorway chargers not working. 

If you bought it on finance it might be worth contacting the finance company about your issue.

Does it charge at home?

Any comment Brad on the two replies you have received? I know you have seen them.

It charges at home fine, seems to be just the motorway ones. When I first had the issue I used the charger and it flashed yellow so I moved the car and luckily for me another e-tron took the spot and charged fine so makes me believe its the car thats the issue and not the charger.

 

I've tried that and they said to contact the dealer for rejection to which they won't accept it.  Not sure on what I can do now.

This could get complicated and confused, so let's clarify some of the terminology involved before going any further. [1] The charger is always, without exception, within the car. It is the inverter that transforms 230 volt AC to 400 volts DC (or 800 volts in some new cars) plus associated electronics for control purposes. [2] The equipment you plug into the car is called in the industry an EVSE or a charge point. It is either [a] a slow charge 230 volt AC electrical power supply plus electronics to communicate with the car, or [b] a fast charge 400 volts DC electrical supply that bypasses the car's charger and goes straight to the battery, plus electronics to communicate with the car. See what I mean about complicated?

Having got that out of the way, the fact you can charge at home on 230 volts AC means the car's charger is working. My questions then are whether the motorway charge point was a slow (230 volt AC) one or a fast (400 volt DC) one, and whether you were using your own charging cable or one fixed (tethered it's called in the industry) to the charge point? Answers to those questions may help us point to the fault.

[Brad1995]

Mainly found the issue to be linked with the rapid chargers.  

[cliffcoggin]

Your own cable or a tethered one on the charge point?

[Brad1995]

The cable provided by the charger.  The issue still persists with every charger I use.  And I struggle to believe each charger I use is faulty 

[cliffcoggin]

In that case I suspect the 400 volt connector on your car is faulty, or that the car does not recognise it correctly. In other words I believe the car is defective and should be returned to the vendor as Steve Q suggested.

I have changed the largely meanless title HELP to something that more accurately represents the problem in order that it can more easily be found by others with a similar problem.
