Driving on the highway during a road trip from florida to wisconsin, our engine stalled while coming to a stop. We managed to get it to an audi dealer and it was determined both turbochargers were broken. Both shafts had snapped and the car was un-drivable leaving us stranded in georgia. This is a design issue for the 4.0t engines and vw/audi has refused to implement a fix beside the oil screen band-aid. The oil screen, since it is not serviceable, will slowly accumulate debris and restrict oil flow to the turbos and cause them to be starved of oil. Simply removing this oil screen would be a suitable fix but audi has refused to acknowledge their design is faulty. This failure could be extremely dangerous if they were to cause the vehicle to stall at speed or worse, have the engine ignite do to the mental on metal grinding of the turbo turbine. Please help us.

Turbo wheel sheared off the shaft and stalled the car while driving at < 5mph in parking lot. Unable to then start car and move it - needed to be pushed to one side to await the tow truck. There were no symptoms or warnings or cel prior to the failure. Others have reported same failure at higher speeds or even on highways. This failure mode is dangerous and could result in loss of vehicle control. Audi should be performing a recall on this for all the vehicles they install this engine model into. I was only recently made aware of the ability to report this issue here, hence the delay in my doing so.

My family and I were driving back home from a 5 hr trip when my car stalled completely on a 4 lane freeway. We stopped at-least 4 times during the trip and the car started with no warning/symptoms or check engine light at all. No hesitation on the power while driving. About 1 hour left until we get home, we hit traffic and luckily we decided to change 1 lane to the right from the farthest left(fast lane) before hitting a full stop. That moment, car stalled and it won't let me restart the car. I have no idea what is going on as I cannot even turn the car off/on and the electronics won't work on me as well. I am now completely blocking the 2nd lane from the left of a 4 lane freeway with a 70 MPH speed limit. Luckily I am not alone in the car and my dad is closely following behind us to help me push the car 2 more lanes to the right to get to the shoulders. Was also fortunate that there was a california highway patrol responding to a 911 call whom helped us by blocking the lanes but had to leave right after after asking us if we are going to be alright without him. I could not imagine what would have happened if I was by myself without nobody I know around me. I wonder if people would have stopped and help me out or I could have been seriously hurt as my car was totally stopped in the middle of a 4 lane freeway and cannot even restart it to limp it to the side shoulders. I called my mercury insurance roadside assistance but 30 mins later, the promised tow truck company still hasn't called. I decided to give it another try, car cranks but won't turn. Successfully restarted it by slightly pressing on the gas but will stall again after the RPM falls below 800 RPM. Still no tow truck, I told my family that I will give it a go as I will try to keep the RPM more than 800 RPM but follow me closely if the car completely dies on me again. Car is now at an audi dealership.
