Used Audi A5 for Sale in Cicero, NY

Hi all I own an Audi A5 2013, 1.8 TFSI coupe, I bought this car as a second hand (used) from trade center UK in Wednesbury I thought "what a great car..." Test drive it liked it bought it few months later it went on limbo mode just like that all of the sudden no warnings nothing, took it to an RAC approved garage ( when I bought the car I was recommended to buy the premium RAC warranty which u have to pay 41.50 UK pounds per month for 3 years ) and they told me that they had to replace a part that has to do with the a/c of the car( air conditioning ) which cost them £1000 then few months later one of my injectors went bad so I had to take it to an RAC approved garage again for the to fix it, when that was done and I got my car back all of the sudden the EPC light came on with the traction control on the dashboard I thought FFS this is some sort of a joke... Took it to a garage again my mechanic had to replace a part that he thought would fix the car which it didn't so when he reported the problem to me he also said that he thinks it could be the control module unit of the car which is the brain of the car apparently it was flooded with water, somehow the when it rains the water makes it way to the ECU but when he hired an electrician the electrician said that there was nothing wrong with the ECU so I thought great at least I don't have to pay money from my own pocket to get it replaced because apparently the ECU is not covered under the premium RAC warranty, the electrician told my mechanic that the part he ordered and got it replaced it was faulty so my mechanic contacted the VW (Volkswagen ) ppl ( because that's where he ordered it from ) and asked for another one, so he installed it and still the problem wasn't fixed so he called me and explained to me what happened and now he had to call out an Audi expert, that was few days ago, when I called my mechanic today to ask him for an update on my car he said that the Audi expert said that there is a fault in the ECU and that he is trying to find a cost effective way to fix it instead of replacing the whole thing, I feel like my mechanic had my car more than what I did I been in and out from garages for a good 2 months and still going. I would not recommend this car to anyone and it's a huge disappointment also worth me ruining that the fuel consumption is really bad I have to top up my car fuel £65 every 2 weeks and I mostly travel back and forth from work to home for 5 days sometimes 4 days a week, 10 minutes to drive to work and 10 minutes to drive back home.
