I have an Audit 1.4 TFSi 2016 that I put into the garage 2 weeks ago to repair a leaking fuel injector. 

Apart from that fault everything else was okay with the car.  I picked the car up and noticed the fuel information on the gauage seemed to be dropping 10 miles for every mile I drove. The repair garage said the problem with the repair is unconnected.  Now I have so many lights

on in my instrument panel warning me things are not working such as Start/Stop, Cruise Control, Stablisation, AUdi Pre Sense, Reverse indicators.

I have no idea why all of it seems to have gone suddenly wrong?

Any idea
