general problems of the 2007 Audi A3

My car stald on me at a shopping center located on 32nd street north of mcdowell rd in phoenix,az. It anti locked on me and was not able to start vehicle. Due to this my car was towed from establishment to a tow garage and is still thier. Im unable to take it out due to I dont have the amount to pay it due to I am a single parent and I dont have a job at moment and I recieve unemployment and the car I still owe to car company called second chance auto sales located on 34thst and van buren in phoenix arizona and from my undrrstanding this vehicle has 3 recall issues that I wasnt aware of. My vehicle started acting wierd prior to incident but no mechanic wanted to look at it and I requested help from the company own mechanic and he too never helped me out. I have all info and phone numbers where to reach company's regsrds to this situation.

Car stalled when driving on highway! would not restart. Broken cam chain!!!!! very expensive repair at this point!!!!!.

Defective cam timing chain tensioner resulting in broken chain, missing time and bent valves! very pricey repair.

Hesitation changing gears with dsg transmission when moving from a standstill to low speed. Strange and erratic behavior on highway when shifting gears. Jerkyness in traffic and low speed gear changes. General drivability and safety issues with automatic transmission.

I was driving and the car wouldnt shift into 3rd gear so I was holding up traffic and struggled to get the car back home. I was told by dealer today I had two bad coils and the megatronic which controld the transmision was going out. I heard 2006 models had a recall on the megatronic but not 2007. I cant believe I need to spend $2500 on anew megatronic for a car that has less than 70k miles and I spent 4290 today for diagnostic, plugs, and coils. The previous 2002 Audi a4 I had had the same problem with the coils but they eventually issued the campaign and reimbursed me for the coils.
