Hi I’ve got Audi a3 2017 keep up to date with services and recently just had one about 5 months ago, I’ve got a problem with my car it was completely fine then next day it makes a weird noise starting up and doesn’t idle cuts off straight away and has put the car into limp mode. So I left come back to it the next day and it is completely fine working driving no issue. Then come back the next day it’s doing the exact same thing as before it’s got a full tank correct fuel there weird ticking noise not too loud coming from the tank area if anyone knows
