I sent my car to a family member for a service. The car drove in fine but not will not select any gear now. It was occasionally throwing all the lights on in the car. It's been plugged in but nothing coming up. Any suggestions please 🙏 

2 litre 2014 A6 Avant C7 auto.

 

You have given us precious little information to work with Claire. Too little in fact to diagnose anything, so please tell us more. Is it manual or automatic gearbox? What lights were coming on, panel lights, cabin lights, or head/side lights? What sort of code reader was it plugged into, professional or amateur? How old is the battery?

If an auto and all selector lights are lit up then the selector switch could be at fault. But this should throw a fault code. 

Thanks for the replies. I had mentioned that it was auto in my post. The battery is a year old. Not sure what diagnostic gear he was using. Lights on were stabilization, traction control, tyre pressure, gearbox malfunction but ok to continue driving. The car drove in fine but when he started it again there was no gears to be found.

Sorry, I somehow missed your mention of an automatic. I reckon the best starting point is to get the car diagnosed on a professional code reader. The cheaper domestic readers are often inadequate to read every available code.

I have had very good history with Carly, (loads of discount codes about too) I am sure that is probably a bad word in this forum but honestly gave me the same codes something like a Topdon did. Having said that I am getting a ross tech but only because nothing else is getting me codes.

What service was done? did they service the gearbox?

Hi if you look at most of these mid range diagnostic platforms they invariably want payments for tokens to do things or a yearly subscription, they all use the same software and if you are a frequent user over a couple of years you will have paid two thirds of the price of VCDS which wont require tokens or a subscription to perform required functions and has lifetime updates for free, with the added bonus its as good as dealer level kit.

Was the advice of any help Claire?

Thanks. Still waiting on different guy to come and plug it in. Fingers crossed. 

Am going to try another new battery to see if that will work.

 

Why another new battery Claire? 
Why not get the existing one professionally checked - along with the alternator output?

What brand is the current battery? 
Regards,

Gareth.
